Description:
BACKGROUND OF THE INVENTION  
         [0001]    Zang Zhi is a kind of fungus. Its academic name is  Antrodia camphorata , also known as “Zang ku”, “red Zang Zhi”, “niou Zang Zhi” or “niou Zang ku.” In Taiwan, Zang Zhi only grows on the inner wall of the empty rotting trunk of  Cinnamomum kanehirai  in the shape of a platy or bell and has a strong cinnamon flavor. People say that Zang Zhi can tranquilize, prevent or treat a cold, promote vital energy circulation, remove blood stasis, promote blood circulation, relieve dyspepsia, detoxify and promote the subsidence of swelling, calm the nerves to reduce stress, alleviate pain, and is the best anticorrosive and detoxicant. It is considered the most expensive wild fungus in the market on Taiwan. The mechanism of anti-tumor cells of Zang Zhi is different from that of Ganoderma sp., which indirectly promotes immunity against tumors. Zang Zhi can directly inhibit or kill cancer cells, and has the capacity to strengthen the heart, adjust immunity, and antagonize the parasympathetic nervous system, and has serous activity. In particular, Zang Zhi can cure a stomachache, bowelache, nausea, diabetes, gout, arthritis, fever, allergy, exorbitant urine proteins, uremia, cirrhosis, hepatomia, flu, etc. Many research institutions have invested human resources and materials in the study of the active constituents of Zang Zhi. Among them, the National Science Council of the Executive Yuan has a special research project to make use of chemical methods, NMR spectrum analysis, and comparative spectrum with known materials to establish the constitutive characteristics of active constituents. Research results of the active constituents show that the water and methanol extracts of Zang Zhi are effective on the inhibition of the growth of  Streptococcus aureus  and  Trichophytone mentagrophytes . Zhankuic acid A, a methanol extract of Zang Zhi has conspicuous inhibition to the lymphoma cells of a p-388 mouse and agglutination of blood platelets. Zhankuic acid B, however, shows little anticholinergic and anti-serotonin effect.  
           [0002]    It is indicated in Gau Sheau Jy&#39;s masters thesis on the triterpenoid of Zang Zhi that Zang Zhi is a new species of Ganodenna discovered in 1990. The extract of the solid fruiting body is obtained by use of acetone, and then is separated and re-crystallized with chromatography LC and PLC. The purity of the extract is identified by TLC scanning and HPLC. The configuration test is done with mass spectrum, infrared spectrum, ultraviolet spectrum, H-NMR, and C-NMR. 3,11-dioxo-8,23-dien-26-oic acid can reduce GPT in the blood of a mouse with the acute hepatitis induced by CCl 4 .  
           [0003]    Most of Zang Zhi grows in the broad-leaf forest areas in Taiwan&#39;s East Coast Mountain Range. However, according to the bulletin of the Niou Zang Conservation Notice issued by the Taiwan Forestry Bureau, this mountain range has been listed as a natural resources conservation zone. Since Zang Zhi is a very popular product which most people are willing to purchase in Asia, Zang Zhi growing outside the said zone have been almost completely harvested. In fact, wild Zang Zhi are not available in the local markets.  
           [0004]    With an estimated sale of 500 kg Zang Zhi per month in Taiwan, the requirement to provide an incubation method for solid culture of Zang Zhi has become more important in recent years.  
         SUMMARY OF THE INVENTION  
         [0005]    The main objective of the subject invention is to provide an incubation method for solid culture of Zang Zhi. The cultured Zang Zhi will have the same pharmaceutical efficacy as the wild one does.  
           [0006]    The other objective of this invention is to provide a solid culture of Zang Zhi by use of the inoculums of Zang Zhi spawn preserved in the Food Industry Research and Development Institute (Taiwan), coded CCRC 35398, to incubate the solid culture in accordance with the incubation method.  
           [0007]    Another objective of the invention is to provide the processed products of the solid cultured Zang Zhi.  
           [0008]    Another objective of the invention is to provide a solid cultured Zang Zhi useful as active constituents.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0014]    This invention provides a method for the solid culture of Zang Zhi, in order to produce the Zang Zhi fruiting body with the constituents and vitality of wild Zang Zhis. The invention&#39;s method for the solid culture of Zang Zhi is to culture the spawn of Zang Zhi through “Bag Log” cultivation, and then to produce the fruiting body of Zang Zhi in the air.  
         [0015]    Before the phase of mycelium culture, it is usual to greatly multiply the spawn for “Bag Log” cultivation, including the following three steps: (1) taking a piece of medium agar containing hyphae preserved in liquid nitrogen, and transfer it into a fresh medium to culture under constant temperature until the exuberant growth of mycelium appears; (2) inoculating the spawn into the “Bag Log” containing cellulolytic substance (for example kernel or spelk); (3) removing the supra old hyphae until the hyphae overgrows in the “Bag Log”; and (4) then inoculating the multiplied spawn into “Bag Log”.  
         [0016]    Before the phase of mycelium culture, one also can greatly multiply spawn with the liquid culture fermentation, and then inoculate them into “Bag Log”. The formulation of liquid culture fermentation is 1-3% of fructose, 0.01-0.1% of magnesium sulfate, 0.1-1% of yeast extract, and 0.05-0.5% of potassium phosphate. The best formulation of liquid culture fermentation followed was 2% of fructose, 0.05% of magnesium sulfate, 0.5% of yeast extract, and 0.1% of potassium phosphate.  
         [0017]    After culturing the slide tube, one may inoculate the multiplied spawn into a 5 liter liquid culture for fermentation under 24-26° C., 240 rpm oscillation for 14 days, and then 90 rpm oscillation for 14 days, and then inoculate them into a 20 liter liquid fermentation, stirring culture for 14 days.  
         [0018]    Here, the so-called “Bag Log” is the plastic bag made from 10-70% of cellulolytic material of stem, stalk, fruit, or spelk of any mushroom or plant (especially, the stems, stalks, and fruits of grass plants or even cellulolytic spelk are better), 10-30% of starch resource (especially, potato is better), and 5-15% of millet (rice bran is better), 1-10% of saccharides (glucose is better), 0.5-2% of phosphate (potassium phosphate is better), and 0.1-1% of sulfate salt (magnesium sulfate is better). Relative humidity is maintained at 60-90%, better at 80%. The pH value of the culture medium is adjusted to be neutral.  
         [0019]    The phase of mycelium culture indicated in this text means a period of sixty days after the spawn is inoculated into “Bag Log”. Mycelium will grow at a temperature from 5° to 32° C.; in particular, 28° C. is the best temperature for the growth of mycelium. “Bag Log” cultivation is under way at a relative humidity of about 60-80%, and better at about 80%. As to the condition of air, 0.1-1% of carbon dioxide is better for the culture.  
         [0020]    After the phase of mycelium culture, the phase of the culture of the fruiting body is next. That is to say 61-90 days after the date of the inoculation of the spawn, the plastic bag of “Bag Log” is to be removed, to let the sawdust medium be completely exposed to the air. During the phase of the culture of the fruiting body, the difference between day and night temperature has to be under strict control. Day temperature is generally maintained between 20° and 30° C., especially, better at 25±1° C.; night temperature is better maintained at 11±1° C.; the difference between day and night temperature is better maintained at 15° C. The relative humidity at the phase of fruiting body culture is controlled between 90 and 95%. In addition, the fruiting body has to be cultured in the moving air, and the carbon dioxide is less than 1%. Generally, solid culture material will be collected after 90-120 days.  
         [0021]    The strain CCRC35398 spawn used in this invention can be obtained from the Food Industry Research and Development Institute, Taiwan. According to the solid culture method of this invention, a solid culture substance was obtained. The solid culture substance is conoid, about 10-30 cm in diameter, 15-30 cm in height, and 0.2-0.6 kg in weight.  
         [0022]    To use the solid culture method described above, one can get the solid Zang Zhi. The solid Zang Zhi can be produced by any of the processing methods known to those skilled in the art, for example, water or alcohol can be used to extract the active constituents, and then known concentration methods such as vacuum concentration or freeze concentration can be used to produce the concentrated product.  
         [0023]    One can use the dehydrated method to do the dehydration, or by a spray-dry or lyophilization method. However, the lyophilization method is the best one to dehydrate the solid substance, and during dehydration the solid substance will not change its characteristic by the effect of oxygen.  
         [0024]    The microscopic particles produced by the spray-dry or other dehydration method can be agglomerated to increase their diameters. These products are poremeric particles with good wettability.  
         [0025]    The comparative HPLC spectrum of the invention&#39;s solid culture Zang Zhi, known liquid cultured Zang Zhi, and wild Zang Zhi is shown in FIG. 1. By analysis of HPLC, the constituents of the fruiting body obtained through the invention&#39;s culture method are similar to those of the wild Zang Zhi and the invention&#39;s Zang Zhi has the activities and functions similar to the wild Zang Zhi&#39;s. These activities and functions include tranquilization, prevention from or treatment of a cold, promoting vital energy circulation, removing blood stasis, promoting blood circulation, relieving dyspepsia, detoxifying and promoting the subsidence of swelling, calming the nerves to reduce stress, alleviating pain, inhibiting bacteria and virus and cancer cells, strengthening the heart, adjusting immunity, and antagonizing the parasympathetic nervous system and serous activity. Zang Zhi can cure a stomachache and bowel ache, nausea, diabetes, gout, arthritis, infection, allergy, exorbitant urine proteins, uremia, cirrhosis, hepatomia, flu and so on. Zang Zhi can regenerate skin and act as human skin or callus material, or as adhesive for bedsore or traumatic skin.  
         [0026]    Furthermore, the invention&#39;s solid cultured substance possesses the abilities to antagonize the free radicals and peroxidation of lipids, and functions to protect the liver and inhibit cancer cells. The invention&#39;s solid cultured substance can be taken as health food to prolong life, and be further developed into new medicines.  
         [0027]    The following working examples will further explain this invention, but not limit this invention. Any application or modification of this invention made by persons skilled in these techniques will fall in the scope of this invention.  
       WORKING EXAMPLES  
       [0028]    The strain CCRC35398 spawn obtained from the Food Industry Research and Development Institute were grown by ferment liquid culture, and then inoculated into the “Bag Log”. The fermented liquid culture contains 2% of fructose, 0.05% of magnesium sulfate, 0.5% of yeast extract, and 0.1% of potassium phosphate. “Bag Log” cultivation is to culture mycelium. “Bag Log” is composed of 65% of the stems, stalks, fruits of grass plants or cellulolytic spelk, 20% of potato, 10% of rice bran, 3.5% of glucose, 1% of potassium phosphate, and 0.5% of magnesium sulfate. Adjust the relative humidity to 80% and pH to 7. Relative humidity was maintained at 60-90%, better at 80%, and the pH of the culture medium was adjusted to being neutral.  
         [0029]    The period of mycelium culture is 60 days after the spawn was inoculated into “Bag Log”. Mycelium will grow at a temperature between 5° and 32° C.; 28° C. is the optimal temperature for the growth of mycelium. “Bag Log” humidity is at 80%, and air condition is 0.2-1% of carbon dioxide.  
         [0030]    After the phase of the mycelium culture, the phase of the culture of the fruiting body is on, that is to say 61-90 days after the date of inoculation of the spawn, the plastic bag of “Bag Log” is to be removed, to let the sawdust medium be completely exposed in the air. During the phase of the culture of the fruiting body, the difference between day and night temperature has to be under strict control. Day temperature is generally maintained between 20° and 30° C.; night temperature is better maintained at 11±1° C.; the difference between day and night temperature is better maintained at 15°EC. The relative humidity of the phase of the fruiting body culture is controlled between 90 and 95%. In addition, the fruiting body has to be cultured in the moving air, and the carbon dioxide is less than 1%.  
         [0031]    In 90-120 days, when the conoid fruiting body grows up to 15 cm in diameter and 25 cm in height, the solid-cultured substance will be collected, and then the substance is about 0.4 kg in weight. The HPLC spectrum of major active elements—triterpenoid—is shown in FIG. 1( 1 ), and the measurements are shown in the following Table 1.

         [0036]    The following Analysis Examination and Pharmacology Examination demonstrate that according to the elements and functions of the concentrated product of the invention&#39;s cultured Zang Zhi fruiting body, its major elements include triterpenoid compounds, water-soluble polysaccharides and chitin.  
         [0037]    Water Soluble Polysaccharides  
         [0038]    Examination by the Food Analysis Center in Japan revealed that solid Zang Zhi fruiting body obtained by the invention&#39;s culture method contains a high volume of water soluble polysaccharides; each 100 g fruiting body having 1.2 to 6.5 g of water soluble polysaccharides.  
         [0039]    Content of Heavy Metals  
         [0040]    Atomic Spectrum Analysis made by the Mircoanalysis Laboratory of Atomic Science Department of National Ching Hwa University reveals the invention&#39;s solid-cultured Zang Zhi has a content of heavy metals as follows:  
                                           Na: 48.7 ppm   Mn: 10.9 ppm    Cd: ND       Mg: 767 ppm    Fe: 100 ppm       Cr: ND           Al: 41.6 ppm   Zn: 16.4 ppm           Ca: 605 ppm       As: ND             K: 0.560%    Hg: ND                     
 
         [0041]    Total Antioxidant Activity  
         [0042]    A comparison among one gram of the concentrated powder of the invention&#39;s solid Zang Zhi substance, the powder of wild Zang Zhi, and the concentrated powder of Ganderma sp. reveals their equivalent of the number of micrograms of Vitamin C as follows:  
                                       Content of one gram powder/           equivalent to the number of       Source   micrograms of Vitamin C                   Powder of wild Zang Zhi   633 ug ascorbic acid/g       Concentrated Powder of Ganderma sp.   854 ug ascorbic acid/g       Concentrated Powder of the invention&#39;s   1180 ug ascorbic acid/g        solid Zang Zhi substance                  
 
         [0043]    The result shows that the total antioxidant activity of the invention&#39;s solid Zang Zhi substance is far higher than that of the fruiting body of wild Zang Zhi and that of Ganderma sp.  
         [0044]    Toxicity Test  
         [0045]    According to the experiment of the acute oral toxicity test LD50, the tested mice were each fed with 2,000 mg/kg of the solid powder of the invention&#39;s Zang Zhi, while the other mice were fed with the specially distilled water as control. The results show that the tested mice neither act abnormally nor die. Hence, the volume of the acute oral toxicity test LD50 is higher than 2000 mg/kg.  
         [0046]    Ames Test  
         [0047]    Under the Ames test, the invention&#39;s Zang Zhi is examined by the plate mixed assay. Five tested bacterial isolates are  Salmonella tiyphimurium  TA97, TA98, TA100, TA102 and TA1535. Each isolate is under five concentrations analysis of 312.5, 625, 1250, 2500 and 5000 ug/plate, respectively. Coincidentally, a negative control group and a positive control group specific to bacterial isolate are included, and each group is triplicate. Test results show that negative control group falls in the acceptable range, and positive control group reflects an increase of mutant bacterial colonies. Whether or not the bacterial isolates are treated under big mouse liver enzyme metabolic system (S9), all tested concentrates do not show an obvious increase of colonies of Ames tested isolates, as shown in table 4.  
                                 TABLE 4                             Salmonella typhimurium  Ames Test                Test               Test Target   examples   Feed dosage × Period   Test result                 Salmonella     Five mutant   tested concentration   Whether under         typhimurium     isolates   (ug/plate)   big mouse liver           required   312.5, 625, 1250,   enzyme metabolic           Histidine of   2500 and 5000 plate   system (S9) or           TA97, TA98,   mixed assay for   not, all tested           TA100, TA102   triplicate.

         [0048]    Anti-Lipid Peroxidation Ability Test  
         [0049]    Anti-lipid peroxidation ability and anti free radical ability of the solid cultured Zang Zhi solid concentrate was tested by the lipid peroxidation in mouse brain homogenization solution. Mouse brain homogenization solution exposed to an oxidative stress was stimulated by Fe 2+  introduction and induced the kinetics of generation of lipid-derived free radical. FIG. 2 shows that while increasing the concentration of triple and 8 fold the invention&#39;s Zang Zhi solid substance concentrate, it has a trend to inhibit lipid peroxidation and reduce the generation of free radical.  
         [0050]    Protection of Liver Function Experiment  
         [0051]    An experimental model using carbon tetrachloride to cause slow damage to the liver of a mouse to discover the effect of different concentrates of Zang Zhi on the slow damage to a mouse liver was established. Twenty-four mice (ICR strain) are divided into 4 groups as shown in Table 5.  
                                 TABLE 5                           Zang Zhi Test Dosage and Animal Group Division            Group   Carbon Tetrachloride Dosage   Dosage   No. of Mice               A   0(control)   0(control)   6       B   40% CCl 4 /olive oil   0(control)   6           (0.3 mg/100 g BW)       C   As above   50 mg(triple)/Kg   6       D   As above   50 mg(8 fold)/Kg   6                  
 
         [0052]    The mice of Groups A and B to D were under a hypodermic injection of olive oil (0.1 ml/100 g BW), and 40% of CCl 4 /Olive oil (0.3 ml/100 g BW) twice a week. The mice of Groups A and D were fed with physiological saline through a stomach tube, while the mice of Groups C and D were fed with two different dosages of extract of the invention&#39;s cultured Zang Zhi for five weeks. Then, the eyepit blood of all mice was collected to examine the biochemical measurement related to liver function. After that, the tested mice were sacrificed and the largest liver leaf was taken out to proceed with the hitopathogenic observation, such as damage to the liver cells, change of lipid, necrosis, cellulose and degree of these changes, and so on. Biochemical tests include activities of GTP and GOT, which are conducted according to the standards of International Clinic Chemistry. The experimental results show that GTP and GOT in the blood of a mouse liver damaged by carbon tetrachloride obviously increased after five weeks. GTP of about 850 units is 20-22 fold above the normal, and GOT of about 1700 units is 40-42 fold above the normal (FIGS.  3 - 4 ). In addition, mice fed with triple and eight fold of concentrated extract of the invention&#39;s Zang Zhi have the capacity to inhibit the increase of GTP and GOT induced by CCl 4 . Particularly, when the GTP and GOT approach the peak, the triple concentrated extract can inhibit the increase of GTP by 37% and the increase of GOT by 65%.  
         [0053]    When comparing the liver tissue of a normal mouse with the liver tissue of the mouse fed on CCl 4  after six weeks, the liver tissue treated with CCl 4  conspicuously shows tumefacient and gray rough surface. However, the liver tissue of the mouse fed on different concentrated Zang Zhi extracts shows no tumefacient and gray rough surface. Besides, by staining, one can see the pile of lipid granules, the tumid liver cells around the middle vein, macrophage and other irritated white blood cells infiltrating the liver cell space, and partial necrosis cells showing nodular transformation. However, the liver tissue of the mouse fed on different concentrated Zang Zhi extracts has no pathogenic changes as described above.  
         [0054]    Table 6 shows the semi-quantification analysis of pathogenic mouse liver tissue. N represents the normal group, D represents CCl 4  damaged group, X3 represents the group fed on triple concentrated extract, X8 represents the group fed on eight fold concentrated extract. It is proved that the concentrated Zang Zhi extract can significantly improve the pathogenic changes.  
                                                                                                 TABLE 6                           Semi-Quantification Analysis of Mouse Pathogenic Liver Tissue                Cell necrosis                        Fat           Tuberous   Biliary               Inflammation   degener-   Local   Cosecutive   transfor-   Prolifer-   Calcifi-           of liver   ation   necrosis   necrosis   mation   ation   cation                        N   0   0   0-1   0   0   0   0       D   2-3   2-3   2   2   0-1   1   0-1       X3   1   1-2   0-1   1-2   0-1   0-1   0-1       X8   0-1   0-1   0-1   1   0   0-1   0-1

         [0057]    In addition, an experiment is conducted to find out the results of inhibiting bowel cancer growth by using 5 powder specimens (New1, New2, New3, New4 and New5), 11 liquid specimens (20L, New2, New3, 520, 521, 522, 523, 524, 525, 526 and 527) as well as their 1:10 specimen dilution by microculture tetrazolium assay. The results as shown in FIG. 5 reveal that in the final concentration {fraction (1/10)} of stock solution can at least inhibit 30% of cancer cell growth, and the specimen 20L can inhibit the growth of cancer cells up to 90%.  
         [0058]    Analysis of Chromosome Mutation in Vitro  
         [0059]    Further, an analysis of chromosome configuration mutation in vitro was conducted to treat Chinese hamster ovary cells with the invention&#39;s Zang Zhi. The cells at middle mitosis were analyzed to observe and measure the frequency of abnormal chromosomes. Analysis of the configuration mutation of chromosome can estimate the ability of the invention&#39;s Zang Zhi to damage the cellular chromosome. Three treatments are given as follows: the first treatment is to add the invention&#39;s Zang Zhi to treat the cells for three hours, without adding the active mouse liver enzymes system (S9); the second one is to add S9 to treat the cells for 3 hours; and the third one is to treat the cells without adding S9 for 20 hours. All tested Zang Zhi concentrations under these three treatments cause no increase of the frequency of chromosomal configuration mutation. The experimental results are shown in the following Table 8.

         [0060]    Analysis of Micronuclei in Animal Body  
         [0061]    The clastogenicity of the invention&#39;s Zang Zhi in the animal body was examined. Further, the risk estimation of human hereditary toxicity was made according to the formation of micronuclei in reticular mouse red blood cells. Twenty-five mice were divided into 5 groups in this experiment. Analysis of the micronuclei reveals that the reaction of invention&#39;s Zang Zhi to circumference blood micronuclei of mouse is negative.
