Description:
TECHNICAL FIELD 
       [0001]    The present invention relates to a composition for suppressing chronic obstructive pulmonary disease (COPD) comprising a  Pistacia weinmannifolia  extract, a fraction thereof, or a compound isolated therefrom and, more particularly, to a pharmaceutical composition for preventing or treating COPD comprising a  Pistacia weinmannifolia  extract, a fraction thereof, or a compound isolated therefrom; a food composition for preventing or improving COPD, and the compound isolated therefrom. 
       BACKGROUND ART 
       [0002]    Chronic obstructive pulmonary disease (COPD, hereinafter), one of the representative lung diseases along with asthma, differs from asthma in that it accompanies an irreversible airway obstruction. COPD is an important disease which is currently ranked as the fourth leading cause of death in the world and shows a unique increase in its occurrence among the top ten diseases. COPD is a disease that occurs due to pathological changes in the bronchioles and lung parenchyma, which are caused by infections in the airway and lung parenchyma, and it is characterized by having obstructive bronchiolitis and emphysema (destruction of lung parenchyma). The types of COPD include chronic obstructive bronchitis, chronic bronchiolitis, and emphysema. The primary risk factor of COPD is thought to be cigarette smoking. Smoke acts as a strong toxic material in the lung tissue and causes promotion of the generation of oxidized materials, proinflammatory factors, and chemotactic factors, thereby promoting excessive transport of inflammatory cells such as neutrophils. The inflammatory cells transported to the inside of the lung tissue also secrete many inflammatory mediators, thus worsening the inflammation in the lung tissue. Examples of the well-known inflammatory mediators may include TNF-α, MIP-1, CXCL-1, etc., and they are used as important markers in inflammatory responses due to cigarette smoke. 
         [0003]    The therapeutic materials used for treating COPD have been developed to improve the inflammation in the lung tissue, and they are mainly steroids, anti-inflammatory agents, etc. However, these therapeutic materials can cause various side-effects such as immunosuppression and resistance, and thus they are not suitable for the COPD patients who require long-term treatment. 
         [0004]    Until now, in the case of COPD such as asthma, therapeutic agents having the effects of anti-inflammation or bronchodilation have mostly been used for the treatment of inflammation. However, a significant number of these conventional therapeutic agents require caution due to many side-effects. Examples of the representative therapeutic agents may include glucocorticoid, leukotriene modifiers, theophylline, etc. In the case of glucocorticoids, they have a strong effect but also have a problem in that they suppress all immune responses and anti-inflammatory responses including even the necessary immune responses instead of acting selectively, and thus there is an issue of drug side-effects and they are thus used for inhalation treatment. In the case of leukotriene modifiers, they have few side-effects but, due to the limited effects, they cannot control asthma when used alone, and thus they are mostly used as a subordinate agent. In the case of theophyllines, they have problems in that they do not have excellent effect and there is also a risk of side-effects. In the case of corticosteroids, they have an excellent therapeutic effect, but, under the long-term treatment, they are known to induce adrenal suppression, decrease of bone density, growth disorder, complications in the eyes and skin, increase of collagen synthesis, etc. in proportion to the dosage and duration of administration. In the case of long-acting β2 agonists such as salmeterol and formeterol, they exhibit a preventative effect against convulsions but they have been warned against because they may cause death of patients under certain conditions. Due to the various side-effects described above, the conventional therapeutic agents for treating inflammation require careful considerations in their use, and thus there is a need for the development of a therapeutic agent having an excellent effect with few side-effects. For this purpose, an accurate understanding of the mechanism of COPD is necessary. 
         [0005]    Until now, the exact mechanism of COPD has been almost unknown, and there has been no therapeutic agent that can fundamentally treat the occurrence and progress of COPD, although various treatments have been attempted. Accordingly, studies on the pathogenesis of COPD and development of a fundamental therapeutic agent thereof based on the same are urgently required. 
         [0006]    Nevertheless, a recent report related to the study of COPD revealed that chemotactic factors such as MIP-2 and CXCL-1, which promote the transport of inflammatory cells, have an important role in the occurrence and development of COPD (Lomas-Neira et al., 2005; Moriyama et al., 2010). In the progress of COPD, chemokines such as MIP-2 and CXCL-1 exhibit chemotactic effects via conjugation with the receptors of airway epithelial cells, pneumocytes, and inflammatory cells and induce an excessive infiltration of inflammatory cells into the inflammatory area in the lung tissue. Additionally, chemokines activate inflammatory cells, thereby producing proinflammatory factors such as TNF-α, IL-1β, IL-6, and IL-8. Specifically, in the case of TNF-α, it activates an inflammatory signaling system such as NF-κB and MAPK, thereby worsening the inflammatory responses. Additionally, chemokines not only produce proinflammatory factors but also produce various growth factors and reactive oxygen species, which cause sustained inflammation responses, damage in the lung parenchyma tissue, and fibrogenesis in the lung tissue (Lo et al., 2013). Due to a series of these reactions, deterioration in the pulmonary function, which is the most distinctive characteristic of COPD patients, is caused. Accordingly, the inhibition of chemokine production is thought to be a very important method for treating COPD. In fact, many researchers have made efforts to develop therapeutic materials for treating COPD with their studies being focused on the inhibition of chemokines (Buenestado et al., 2013). 
         [0007]    Meanwhile,  Pistacia weinmannifolia  J. Poiss, Ex Franch is a plant widely cultivated near the Yunnan Province of China, and it has been used for treating shigellosis, gastroenteritis, flu, and headache since ancient times. According to a previous report, two compounds isolated from the plant were shown to have the ability to remove free oxygen radicals (Zhao X. et al.,  Biochim Biophys Acta,  1725, 103-110, 2005). However, except for the above report, the effect of  Pistacia weinmannifolia  extract, a fraction thereof, or a compound isolated therefrom with respect to the treatment or prevention of COPD has not been known.

         [0027]    The pharmaceutical composition of the present invention may further include a pharmaceutically acceptable carrier. 
         [0028]    COPD differs from asthma in that it accompanies an irreversible airway obstruction. COPD is a disease that occurs due to pathological changes in the bronchioles and lung parenchyma which are caused by infections in the airway and lung parenchyma, and it is characterized by having obstructive bronchiolitis and emphysema (destruction of lung parenchyma). The types of COPD include chronic obstructive bronchitis, chronic bronchiolitis, and emphysema. Preferably, the subject disease of the composition of the present invention may be COPD. However, the subject disease of the present invention is not limited to those diseases which accompany an applicable irreversible airway obstruction and occur due to pathological changes in the bronchioles and lung parenchyma which are caused by infections in the airway and lung parenchyma. 
         [0029]    For the purpose of the present invention, the  Pistacia weinmannifolia  extract, a fraction thereof, or a compound isolated therefrom according to the present invention may be used for the prevention or treatment of COPD. 
         [0030]    As used herein, the term “ Pistacia weinmannifolia  extract” refers to all of an extract obtained by extracting the roots, leaves, stems, etc., of  Pistacia weinmannifolia  using a suitable solvent; a diluted or concentrated solution of the extract; a dried product obtained by drying the extract; and a coarse purified product or purified product thereof. The  Pistacia weinmannifolia  extract may be extracted from various organs of natural, hybrid, and modified plants of  Pistacia weinmannifolia , and in particular, an extract obtained from the stems of  Pistacia weinmannifolia , etc., but is not limited thereto. 
         [0031]    The  Pistacia weinmannifolia  extract of the present invention may be prepared by a conventional extraction method in the art such as sonication extraction, filtration, reflux extraction, etc.  Pistacia weinmannifolia  for use may be purchased from the commercial market or obtained by collecting those grown or cultivated in nature. 
         [0032]    The  Pistacia weinmannifolia  extract of the present invention may be isolated according to the conventional method for preparing an extract from a natural product known in the art, i.e., using a conventional solvent under the conventional temperature and pressure conditions. 
         [0033]    For the preparation of the  Pistacia weinmannifolia  extract of the present invention, solvents such as water, a C 1 -C 4  alcohol (low-grade anhydrous or hydrous alcohol), or a mixed solvent thereof may be used, but are not limited thereto. For example, the  Pistacia weinmannifolia  extract may be prepared using methanol, and in particular, using 70% to 95% methanol as an extraction solvent. Additionally, for solvent extraction, the extraction may be performed by heat extraction, cold extraction, reflux extraction, or sonication extraction. These extractions may be performed at room temperature or at low temperature or under heat treatment. Subsequently, the  Pistacia weinmannifolia  extract may be obtained by filtration and/or concentration under reduced pressure of the extract, and the extract process may be repeated two or three times, and may include an additional step of filtration, concentration, lyophilization, etc. 
         [0034]    In a preferred embodiment of the present invention, the stems of collected  Pistacia weinmannifolia  were dried and pulverized. The pulverized powdered sample was treated with 20 volumes of methanol based on the dry weight of the sample, and a 70% to 95% methanol extract was obtained therefrom. Subsequently, the resultant was subjected to filtration and concentration under reduced pressure and a  Pistacia weinmannifolia  methanol extract was obtained therefrom. 
         [0035]    As used herein, the term “fraction” refers to a resultant obtained from a mixture containing various constituting components by a fractionation method to isolate a particular component or group. In the present invention, fraction refers to a resultant obtained from a  Pistacia weinmannifolia  extract by a fractionation method to isolate a particular component or group. 
         [0036]    In order to obtain the  Pistacia weinmannifolia  fraction according to the present invention, a conventional solvent for fractionation known in the art, e.g., water; a polar solvent of a low-grade anhydrous or hydrous C 1 -C 4  alcohol such as ethanol and methanol; a non-polar solvent such as hexane, butanol, ethyl acetate, chloroform, and dichloromethane; or a mixed solvent thereof may be used, but the solvent is not limited thereto. 
         [0037]    The  Pistacia weinmannifolia  fraction of the present invention may further include those obtained by applying additional purification to the fractionation process. For example, a fraction obtained by passing the  Pistacia weinmannifolia  fraction of the present invention through an ultrafiltration membrane having a predetermined molecular weight cut-off value and a fraction obtained by various purification methods additionally performed by separation via various chromatographies (those prepared for the separation according to size, electric charge, hydrophobicity, or hydrophilicity) are included in the  Pistacia weinmannifolia  fraction of the present invention. 
         [0038]    In a preferred embodiment of the present invention, the methanol extract of  Pistacia weinmannifolia  obtained above was suspended by adding distilled water thereto and adding an equal amount of hexane to separate it into a hexane layer and a water layer. After repeating the above process three times, the resultant was filtered and concentrated under reduced pressure to obtain a hexane fraction. Then, the hexane fraction was removed and the remaining water layer was treated with an equal amount of chloroform to obtain a chloroform fraction in the same manner, and the remaining water layer was treated with an equal amount of ethyl acetate to obtain an ethyl acetate fraction in the same manner. The remaining water layer was again treated with an equal amount of butanol to obtain a butanol fraction. 
         [0039]    In an exemplary embodiment of the present invention, a methanol extract of  Pistacia weinmannifolia  was loaded and a fraction thereof was obtained at an elution rate of 9 mL/min using a methanol/water [0:100-&gt;100:0 (v/v)] solvent. Likewise, active fractions 1 to 7 were obtained. 
         [0040]    In an exemplary embodiment of the present invention, cell viability rate was examined by treating cells with six different kinds of active fractions of  Pistacia weinmannifolia  at different concentrations. As a result, no toxicity was observed in cells when treated at a concentration of 1 μM or below ( FIG. 5  and Table 3). 
         [0041]    Additionally, in an exemplary embodiment of the present invention, cells were treated with six different kinds of active fractions of  Pistacia weinmannifolia  at different concentrations to examine the inhibitory effect against the production of MUC5AC protein, thereby confirming the excellent inhibitory effect of the active fractions compared to the extract ( FIG. 7  and Table 4). 
         [0042]    Additionally, the  Pistacia weinmannifolia  extract or a fraction thereof may include the compound represented by the following Formula 1 or Formula 2. 
         [0000]    
       
                 
         
             
             
         
       
     
         [0043]    In an exemplary embodiment of the present invention, three kinds of novel active compounds capable of inhibiting inflammatory reactions of COPD were isolated from the  Pistacia weinmannifolia  extract or a fraction thereof. Specifically, the active fraction 5 of the  Pistacia weinmannifolia  extract was eluted again at an elution rate of 14 mL/min using a methanol/water [10:90-&gt;100:0 (v/v)] solvent to obtain small fractions. Among the small fractions, a novel compound PW12 represented by Formula 1 and a novel compound PW13 represented by Formula 2 were isolated. 
         [0044]    Specifically, regarding the two kinds of novel active compounds, the molecular formula of the compound of Formula 1 (PW12) is C 30 H 22 O 8  and 2′,4′3″,2′″,4′″-pentahydroxy-4-O-3″-bichalcone by IUPAC nomenclature, and the present inventors named it as pistachalcone. The molecular formula of the compound of Formula 2 (PW13) is C 45 H 34 O 12  and di-(2,4-dihydroxybenzoyl)-(3,4-dihydroxyphenyl)-(4-hydroxyphenyl)-cyclobutane-3-O-4′-bichalcone by IUPAC nomenclature, and the present inventors named it as pistachalcone B. 
         [0045]    In a preferred embodiment of the present invention, cell viability rate was examined by treating cells with the  Pistacia weinmannifolia  extract or the two different compounds extracted from the fraction of  Pistacia weinmannifolia  at different concentrations. As a result, no toxicity was observed in cells when treated at a concentration of 1 μM or below ( FIG. 6  and Table 3). 
         [0046]    Additionally, in an exemplary embodiment of the present invention, cells were treated with the  Pistacia weinmannifolia  extract or three different compounds extracted from the fraction of  Pistacia weinmannifolia  at different concentrations to examine their inhibitory effects against the production of MUC5AC protein, thereby confirming their excellent inhibitory effects compared to the extract ( FIG. 7  and Table 4). 
         [0047]    Cytokines such as TNF-α and CXC chemokines such as MIP-2 are known to be involved in the trafficking activity of neutrophils from pulmonary circulation to pulmonary alveoli. These are cytokines or chemokines which are all associated with inflammation, and in the case of occurrence of COPD, the number of neutrophils increases and the cytokines or chemokines are released. Accordingly, inflammations occur in the airway, muscle walls become thick, and mucus secretion increases, thereby causing an airway obstruction. Once the bronchi become obstructed, the alveoli become dilated and damaged, thereby deteriorating the ability of exchanging between oxygen and carbon dioxide and increasing the risk of respiratory failure. In particular, the expression of these cytokines or chemokines is known to increase in patients with COPD, thus confirming their correlation with the COPD. 
         [0048]    Accordingly, COPD responses can be suppressed by inhibiting the secretion of proteins selected from CXCL-1, TNF-α, and MIP-2. 
         [0049]    Meanwhile, CD 4+  cells are known as cells promoting immune functions and the excess increase of the CD 4+  cells may result in autoimmunity. COPD patients are known to significantly increase the number of CD 4+  cells compared to that of normal people ( Proceedings of the American Thoracic Society , Vol. 4, No. 7 (2007), pp. 512-521). 
         [0050]    Meanwhile, in the case of COPD, the number of neutrophils Gr-1 +  cells also increases ( Eur Respir J  2011; 38: 285-294.; Nikota et al.  Respiratory Research  2011, 12: 39). 
         [0051]    Accordingly, COPD responses can be suppressed by reducing the number of CD 4+  cells and neutrophils Gr-1 +  cells. 
         [0052]    In summary, the  Pistacia weinmannifolia  extract, a fraction thereof, or a compound isolated therefrom of the present invention may have the following activity: 
         [0053]    (a) reducing the number of inflammatory cells around the bronchi or the blood vessels and the number of neutrophils; 
         [0054]    (b) reducing the number of CD 4+  cells or neutrophils Gr-1 +  cells; 
         [0055]    (c) inhibiting the production of CXCL-1; 
         [0056]    (d) inhibiting the production of TNF-α; or 
         [0057]    (e) inhibiting the production of MCP-2. 
         [0058]    In an exemplary embodiment of the present invention, the inhibitory effects of the  Pistacia weinmannifolia  extract and a fraction thereof obtained as described above against COPD were examined. As a result, the methanol extract of the  Pistacia weinmannifolia  according to the present invention exhibited a significant inhibition in the number of neutrophils in an animal model inhaled with a standard cigarette extract (see Table 5) and also reduced the number of CD 4+  cells and neutrophils Gr-1 +  cells (see Table 6), CXCL-1 (see Table 7), TNF-α (see Table 8), and MIP-2 (see Table 9). 
         [0059]    From the results above, it was confirmed that the  Pistacia weinmannifolia  extract and a fraction thereof of the present invention can be effectively used for the prevention and treatment of COPD. 
         [0060]    Accordingly, the present invention provides a composition for preventing or treating COPD, containing the  Pistacia weinmannifolia  extract, a fraction thereof, or a compound isolated therefrom as an active ingredient, and a pharmaceutically acceptable carrier. 
         [0061]    The COPD may be selected from the group consisting of chronic obstructive bronchitis, chronic bronchiolitis, emphysema, multiple sclerosis, and acute and chronic inflammation, and preferably a chronic obstructive disease, but the applicable multiple sclerosis, and acute and chronic lung diseases are not limited by the same. 
         [0062]    As used herein, the term “chronic obstructive pulmonary disease (COPD)” is a respiratory disease, in which an abnormal inflammatory reaction occurs in the lung by the inhalation of harmful particles or gas(es) and a progressive airway limitation occurs, thereby deteriorating pulmonary functions and inducing respiratory distress. Major symptoms of COPD include difficulty breathing, etc., along with chronic cough or chronic phlegm (sputum), and the representative therapeutic agents may include bronchodilators such as beta agonists, anticholinergics, methylxanthines, etc., and inhaled corticosteroids, etc. In the present invention, COPD may refer to chronic bronchitis or emphysema, but is not limited thereto. 
         [0063]    As used herein, the term “chronic bronchitis” refers to a disease in which sputum production lasts for two consecutive years with at least three months of sputum production each year and a long-lasting cough is accompanied. Smoking, air pollution, and bronchial damage by stimulus due to occupational exposure appear to be the possible causes of the disease, and major symptoms include chronic cough, sputum production, difficulty breathing during exercises, etc. Additionally, an acute deterioration, which is a characteristic of COPD, may occur, during which difficulty breathing rapidly worsens within a few hours to a few days, the amount of sputum may increase or the features of the sputum may change from being mucous to being pyogenic while its color turns to dark yellow or bluish and its viscosity increases thus making it difficult to spit out the sputum. 
         [0064]    As used herein, the term “emphysema” refers to an abnormal and permanent dilated state of peripheral airway and alveoli caused by the destruction of the distal airspace of terminal bronchioles. Emphysema occurs by the inhalation of harmful particles and gases and the most meaningful clinical risk factor is known to be smoking. Major symptoms of emphysema include chronic cough, sputum, difficulty breathing, etc. 
         [0065]    As used herein, the term “prevention” refers to” to all activities capable of inhibiting or delaying the occurrence of multiple sclerosis, and acute and chronic lung diseases including COPD by administering a composition containing according to the present invention. 
         [0066]    As used herein, the term “treatment” refers to” all activities capable of alleviating or improving the symptoms of multiple sclerosis, and acute and chronic lung diseases including COPD by administering a composition containing according to the present invention. 
         [0067]    The pharmaceutical composition of the present invention may be used as a single formulation or a complex formulation by further including a drug(s), which is(are) known to have approved effects for the treatment of multiple sclerosis, and acute and chronic lung diseases. 
         [0068]    As used herein, the term “pharmaceutically acceptable” refers to the properties of neither significantly stimulating a bioorganism nor inhibiting the biological activities and characteristics of the active material(s) for administration. The pharmaceutical composition of the present invention including a pharmaceutically acceptable carrier may be prepared in various types of oral or parenteral formulations. For the preparation of formulations, commonly used fillers, extenders, binders, humectants, disintegrating agents, diluents such as surfactants or excipients may be used. 
         [0069]    Solid formulations for oral administration may include tablets, pills, powders, granules, capsules, etc. The solid formulations may be prepared by adding at least one excipient, e.g., starch, calcium carbonate, sucrose or lactose, gelatin, etc. Additionally, lubricants such as magnesium stearate, talc, etc., may be used in addition to the simple excipients. Examples of liquid formulations for oral administration may include suspensions, formulations for internal use, emulsions, syrups, etc., and various kinds of excipients, e.g., humectants, sweeteners, fragrances, preservatives, etc., may be used in addition to simple diluents such as water and liquid paraffin. Formulations for parenteral administration may include sterile aqueous solutions, non-aqueous solvents, suspensions, emulsions, lyophilized preparations, and suppositories.

       DETAILED DESCRIPTION OF THE INVENTION 
       [0097]    Hereinafter, the present invention will be described in more detail with reference to the following Examples. However, these Examples are for illustrative purposes only, and the invention is not intended to be limited by these Examples. 
       Example 1 
     Preparation of a  Pistacia weinmannifolia  Extract, Fraction, and Compound Thereof 
       [0098]    1-1. Preparation of a  Pistacia weinmannifolia  Extract 
         [0099]    A methanol extract of  Pistacia weinmannifolia  J. Poiss. Ex Franch was purchased from the Overseas Plant Extract Bank of the Overseas Biomaterial Hub Center of the Korean Research Institute of Bioscience and Biotechnology (KRIBB). 
         [0100]    Regarding the extraction process,  Pistacia weinmannifolia  stems (20 kg) were collected and the water contained therein was removed by a dryer (50° C. to 55° C.) under natural drying (drying in the shade) and ground. The ground powdered sample was treated with methanol (30 L) based on the dry weight of the ground powdered sample and was subjected to extraction at room temperature. Then, the resultant was filtered and concentrated under reduced pressure to obtain a  Pistacia weinmannifolia  methanol extract (542.2 g). The  Pistacia weinmannifolia  methanol extract obtained subsequently in the following experiment was named as a total extract. 
         [0101]    1-2. Preparation of a Fraction of  Pistacia weinmannifolia    
         [0102]    The total  Pistacia weinmannifolia  extract (542.2 g) obtained in Example 1-1 was suspended by adding water (5 L) and treated with an equal amount of hexane to separate the mixture into a water layer and a hexane layer. The entire process was repeated three times in the same manner, and the resultants were filtered and concentrated under reduced pressure to separate a hexane fraction (48.5 g). After separating the hexane layer in the same manner, the remaining water layer was separated in the same manner by adding an equal amount of chloroform to obtain a chloroform fraction (16.3 g). In the same manner, the chloroform layer was separated and the remaining water layer was separated in the same manner by adding an equal amount of ethyl acetate to obtain an ethyl acetate fraction (53.7 g). In the same manner, the ethyl acetate was separated and the remaining water layer was separated in the same manner by adding an equal amount of butanol to obtain a butanol fraction (114 g). The remaining water layer was concentrated to obtain a water fraction (186.5 g). 
         [0103]    1-3. Preparation of an Active Fraction of  Pistacia weinmannifolia    
         [0104]    For MPLC analysis, a column (20 mm×250 mm; Resin; Zeoprep C18, 10 μm) was installed to an MPLC device (Interchim) and methanol extract (2 g) was loaded repeatedly. In particular, a methanol/water [0:100-&gt;100:0 (v/v)] solvent was used at an elution rate of 9 mL/min and active fractions (Fr. 1 to Fr. 7) were obtained by detecting at a wavelength of UV 200 nm to 400 nm. The MPLC analysis results are shown in  FIG. 1  and Table 1.

         [0105]    1-4. Analysis of an Extract and a Fraction of  Pistacia weinmannifolia    
         [0106]    To examine the active fractions of the ethyl acetate fraction of  Pistacia weinmannifolia  obtained in Example 1-2, the fractions were analyzed by ultra performance liquid chromatography (UPLC). 
         [0107]    First, for the UPLC analysis, the ethyl acetate fraction (53.7 g) was filtered once with a 0.25 mm membrane filter for UPLC. After installing a column (Waters BEH C18 column, 2.1×100 mm, 1.7 mm) to the UPLC device (Waters UPLC-Q-TOF), each of the filtered fractions was loaded in an amount of 0.3 μL. 
         [0108]    In particular, the solvent used for the UPLC analysis was acetonitrile+0.1% formic acid/water+0.1% formic acid [10:90-&gt;100:0 (v/v)], and the elution rate was set at 0.4 mL/minute. With respect to the active fractions and separated materials, the degree of separation was confirmed from the UPLC in the form of chromatography at a wavelength of UV 200 nm to 400 nm via mass spectrometry (MS) using a detector.

       Example 2 
     Cytotoxicity Test 
       [0115]    To confirm the cytotoxicity of a  Pistacia weinmannifolia  extract, a fraction thereof, and a compound isolated therefrom, which were prepared and extracted in Example 1, experiments were performed by applying the method described in the existing references (Ishiyama et al., Talanta, 44, pp. 1299-1305, 1997; Tominaga et al.,  Anal. Commun.,  36, pp. 47-50, 1999). 
         [0116]    2-1. Preparation of Cells and Cultivation 
         [0117]    H292 (CRL-1848) was purchased from the American Type Culture Collection (ATCC). The H292 cells were cultured in RPMI medium (SH30027.01, RPMI 1640, Gibco) containing 10% fetal bovine serum and antibiotics, and cultured in the condition of humidified 5% CO 2  atmosphere at 37° C. TNF-α was purchase from a company (300-01A, Peprotech, USA) and used. 
         [0118]    2-2. Cell Viability Assay 
         [0119]    The cells in a medium (GM) were placed in a 96-well plate at a density of (1×10 3  cells/well). After 24 hours, the cells were cultured along with a sample for one day. The cell viability rate was read via trivalues according to the manufacturer&#39;s manual using the Cell Counting Kit-8 (CK04-01, Dojindo Molecular Technologies, ML). The absorbance was measured using the VERSAmax microplate reader (SMP500-14915, Molecular Devices, USA) and the measured absorbance was converted into a cell number via a standard curve. 
         [0120]    2-3. Evaluation of Cytotoxicity of a  Pistacia weinmannifolia  Extract, a Fraction, and a Compound Isolated Therefrom 
         [0121]    H292 cells, human mucosa cells of lung cancer, were suspended in RPMI medium (Gibco) containing 10% fetal bovine serum in a concentration of 5×10 4  cells/mL, inoculated to a 96 well-plate in an amount of 100 μL per each well, and allowed to be attached thereto for 12 hours. Six active fractions of  Pistacia  and 3 single compounds (PW11, PW12, and PW13) were treated according to concentrations, and cultured for 24 hours. As explained in the cell counting CCK-8 kit (Dojindo Molecular Technologies, ML), the CCK-8 solution (10 μL) was mixed with the medium (90 μL). The mixture (100 μL) was added to each well, reacted for the minimum 30 minutes to the maximum 4 hours, and the absorbance was measured at 570 nm. The cell viability was calculated according to Equation 1 above with reference to the negative control, which was treated with DMSO in a concentration of 0.2%, set at 100%. The results are shown in Table 3 below.

     Effect of Inhibiting the Production of MUC5AC Protein 
       [0123]    To analyze the effects of the  Pistacia weinmannifolia  extract, a fraction thereof, and a compound isolated therefrom, prepared and extracted in Example 1, on the prevention and treatment of inflammatory diseases such as COPD, the inhibitory effect of the  Pistacia weinmannifolia  extract, a fraction thereof, and a compound isolated therefrom against the secretion of a related protein, MUC5AC. In this regard, to confirm the inhibitory effect of the samples in Examples on the production of MUC5AC protein, experiments were performed using the method described in the reference (Sikder, M A. et al.,  Phytotherapy research : PTR. 28, 62-8, 2014). 
         [0124]    3-1. Effect of Inhibiting the Production of MUC5AC Protein by a  Pistacia Weinmannifolia  Extract, a Fraction, and a Compound Isolated Therefrom 
         [0125]    The supernatant, which was recovered for the immunoassay of the produced MUC5AC, was aliquoted into a 96 well-plate in an amount of 50 μL and dried in a homeostat set at 50° C. The resultant was washed with PBS containing 1% BSA, reacted with MUC5AC antibody (ab3649, abcam) at room temperature for one hour, and aliquoted with the secondary antibody and reacted for one hour. The resultant was rewashed, reacted with 3,3′,5,5′-tetramethylbenzidine peroxide solution (54827-17-7, Sigma-Aldrich) for 20 minutes, and the reaction was stopped with a sulfuric acid solution and the coloration was measured at 450 nm using a microplate reader (VERSAmax microplate reader, SMP500-14915, Molecular Devices, USA). The results are represented by the graph in  FIG. 1  and are also shown in Table 4 below.

     Evaluation of the Effect of a Animal Model with COPD Induced by a Standard Cigarette Extract 
       [0126]    4-1. Experimental Animals and Induction of Bronchial Chronic Obstructive Pulmonary Disease 
         [0127]    In this experiment, 8-week-old male BALB/c mice with an average body weight of about 20 g were used as experimental animals. After an adaptation period for a week, the animals, in which no abnormalities were observed in basic physical examination, were subjected to the experiment. 
         [0128]    Sixty cigarettes of a standard cigarette, Coresta Monitoring Cigarette 7 (CM7; Heinr Borgwaldt, Germany), isopropanol, ethanol (Merck, Germany), and n-heptadecane (Sigma-Aldrich, USA) were used. As an experimental equipment, an automatic smoking machine (ISO 3308 standard, an automatic smoking device, Model: RM20, Heinr Borgwaldt) was used. 
         [0129]    Specifically, the collection of standard cigarette CM7 smoke condensates was performed in a smoking room (temperature: 22±2° C.; relative humidity: 60±5%) according to the ISO 3402 standard, and the cigarettes were smoked using an RM20 (Heinr Borgwaldt, Germany) automatic smoking machine (ISO 3308 standard) according to the ISO 3308 standard under the following conditions: smoke volume: 35.0±0.3 mL; smoking cycle: 60±0.5 seconds; smoking time: 2.00±0.02 seconds; and tip paper length+3 mm (overwrap+3 mm). Additionally, cigarette smoke condensates were collected on a 92 mm Cambridge filter, ISO 3308 standard) (ISO 3308, 2000). 
         [0130]    The Cambridge filter having the cigarette smoke condensates collected thereon was separated from a cigarette holder and placed in each of 100 mL Erlenmeyer flasks, and 50 mL of isopropanol as the extraction solvent was added thereto and well shaken. Then, the contents in the flask were extracted after allowing them at room temperature for at least 8 hours. Upon extraction, the extract was filtered and concentrated under reduced pressure, and the concentrates in the three Erlenmeyer flasks were collected in a scintillation vial and completely concentrated using a nitrogen gas. A COPD mouse model was prepared by anesthetizing the animal with 7% chloral hydrate followed by allowing them to inhale the mixture of (LPS+CS) [LPS (100 μg/mL) and a standard cigarette extract (cigarette smoking; CS; 4 mg/mL) is mixed in a 1:1 ratio] in an amount of 100 μL through the nose once a week for 3 weeks. Specifically, after weakly anesthetizing a mouse, when there was no movement, the front teeth were immobilized using a rubber band and the mixture of (LPS+CS; 50 μL each to a total amount of 100 μL) was allowed to inhale via through the nose. 
         [0131]    The experimental group was divided into (i) a normal group without any treatment (NC); (ii) a control group treated with (LPS+CS), (COPD); and (iii) an experimental group orally administered with  P. weinmannifolia  (30 mg/kg) one hour before the treatment with (LPS+CS) ( P. weinmannifolia ). Upon completion of the experiment, blood, lung lavage fluid, and lung tissue were isolated from the mice of each group. 
         [0132]    4-2. Measurement of Total Granular Materials 
         [0133]    The Cambridge filter having the cigarette smoke condensates collected thereon was separated from a cigarette holder and placed in each of 100 mL Erlenmeyer flasks, and 50 mL of isopropanol as the extraction solvent was added thereto and well shaken. Then, the contents in the flask were extracted after allowing them at room temperature for at least 8 hours. Upon extraction, the extract was filtered and concentrated under reduced pressure, and the concentrates in the three Erlenmeyer flasks were collected in a scintillation vial and completely concentrated using a nitrogen gas. The TPM (total particulate matter) content in the standard cigarette was calculated using Equation 2 below.

     Effect of Inhibiting the Production of Inflammatory Cells in the Bronchoalveolar Lavage Fluid 
       [0135]    To measure the secretion of bronchoalveolar lavage fluid and the total cell number by a  Pistacia weinmannifolia  extract, the mouse bronchi were treated with ACK (8.3 g NH 4 Cl, 1 g KHCO 3  in 1 L demineralized water+0.1 mM EDTA) solution at 37° C. for 5 minutes to lyse red blood cells, again washed with FBS-free/DMEM medium, and stained with 0.04% trypan blue, and the total number of cells was counted. 
         [0136]    Specifically, after the blood collection, the mice were dissected. For the isolation of cells from the bronchoalveolar lavage fluid (BALF), a syringe containing 1 mL of FBS-free DMEM medium was injected into the trachea and fixed with a string, and then cells were separated by performing circulation three times and were treated with ACK solution at 37° C. for 5 minutes to lyse red blood cells. Then, the cells were washed with FBS-free DMEM medium, stained again with 0.04% trypan blue, and the total number of cells was counted. In particular, the total extract by methanol obtained in Preparation Example 1 was used. 
         [0137]    Table 5 below shows the results of the effect of the methanol extract of  Pistacia weinmannifolia  (total) on the production of neutrophils, among the total inflammatory cells in the bronchoalveolar lavage fluid in the COPD animal model induced with a standard cigarette extract.

         [0141]    As can be confirmed in Table 5 above, the animal model treated with the standard cigarette extract after the pretreatment with the  Pistacia weinmannifolia  methanol extract of the present invention showed a decrease in the total number of inflammatory cells within the bronchoalveolar lavage fluid and in the number of neutrophils among the inflammatory cells, whereas the animal model treated with the standard cigarette extract showed a rapid increase in the number of neutrophils. In particular, it was confirmed that the pretreatment with a methanol extract significantly reduced the total number of inflammatory cells (70.6%, P&lt;0.05) and the amount of neutrophil production (59.8%, P&lt;0.05).

     Effect of Inhibiting the Number of CD 4+  Cells and Neutrophils Gr-1 +  Cells in the Bronchoalveolar Lavage Fluid 
       [0142]    The BAL cells isolated in Example 5 were adjusted to 5×10 5  cells and subjected to immunofluorescence staining at 4° C. PE-anti-CD4 (553047, BD Pharmingen) and PE-anti-Gr-1 (553128, BD Pharmingen) were added to the cells, respectively, and reacted on ice for 30 minutes. After the reaction, the cells were washed at least 3 times with phosphate-buffered saline, and the frequency of CD 4+  cells and neutrophils Gr-1 +  was analyzed as a percentage using the Cell Quest program (643274, BD Pharmingen) of a flow cytometer. Then, the absolute number of cells in each tissue was calculated based on total cells by applying the total number of cells. 
         [0143]    Table 6 below shows the measurement results of the effects of a methanol extract of  Pistacia weinmannifolia  on the number of the CD 4+  cells and neutrophils Gr-1 +  within the bronchoalveolar lavage fluid in the COPD-induced animal model.

In contrast, the group administered with a  Pistacia weinmannifolia  extract (30 mg/kg) showed an inhibition in the number of CD 4+  cells compared to the COPD-induced group by 70.3% (P&lt;0.05), and also an inhibition in the number of neutrophils Gr-1 +  by 86.7% (P&lt;0.05). 
       Example 7 
     Effect of Inhibiting CXCL-1, TNF-α, and MCP-2 in the Bronchoalveolar Lavage Fluid 
       [0148]    The levels of CXCL-1, TNF-α, and MCP-2 in the bronchoalveolar lavage (BALF) isolated from the mice were measured by an enzyme-linked immunosorbent assay (ELISA). An antibody specific for each of CXCL-1, TNF-α, and MCP-2 was diluted in coating buffer (291195, R&amp;D System), coated on microwells, and incubated at 4° C. overnight. Each well was washed 3 times with washing buffer, and then 100 μL of serum (10-fold diluted) was aliquoted to each well. Each well was placed at room temperature for 1 hour, washed twice with washing buffer, and each well was treated with 100 μL of avidin-conjugated HRP (DY998, R&amp;D System) placed at room temperature for 1 hour, and washed. The TMB substrate in an amount of 100 μL was added to each well, placed in a dark room for 30 minutes, and treated with 50 μL of a stop solution. Then, the absorbance was measured at 450 nm using an ELISA reader (Emax, Molecular Devices). 
         [0149]    Table 7 below shows the measurement results of the effect of a methanol extract of  Pistacia weinmannifolia  on the production of CXCL-1 within the bronchoalveolar lavage fluid in the COPD-induced animal model.
