BACKGROUND ART
A medicinal herb processing technique that is a traditional Chinese medicine manufacturing technique is called “Po-je”, “Hap-hwa”, “Hap-yak”, “Su-chi”, “Po-ja”, “Bub-je” and “Su-sa” in Korean. This technique can be defined as a medicine manufacturing technique of changing the inherent properties of medicinal herbs by processing the medicinal herbs on the basis of the Chinese medicine theory.
The objects of processing medicinal herbs are to clarify medicines, facilitate the storage of medicines, reduce or remove the toxicity or side effects of medicines, change the properties of medicines to make the medicines more effective, enhance the therapeutic effects of medicines, and the offensive odor and taste of medicines to facilitate the intake of the medicines.
Meanwhile, in the manufacture of cosmetic products, raw materials having various effects, including skin whitening, wrinkle reduction and skin protection, are screened and added. Among these effects, the antioxidant effect removes reactive oxygen species, which are the cause of skin aging, to retard or prevent skin aging, changes a dull and inelastic skin to a fresh and clear skin, and makes the skin to look healthy in appearance. However, only a limited number of materials are known to have the antioxidant effect, and a small number of materials which are currently being used are chemically synthesized.
Recently, various cosmetic products which employ natural materials in order to reduce skin irritation caused by various chemical substances have been developed. In addition, natural materials have reduced side effects on the skin and receive a great deal of attention from consumers. Thus, many efforts to develop natural materials useful as cosmetic raw materials are being made.

BEST MODE FOR CARRYING OUT THE INVENTION
The present invention relates to an antioxidant cosmetic composition containing, as an active ingredient, an extract of at least one of processed peony, Polygonati rhizoma and lily.
The present invention also relates to an antioxidant cosmetic composition containing a mixture of an extract of at least one of processed peony, Polygonati rhizoma and lily and an extract of at least one of unprocessed peony, Polygonati rhizoma and lily. Herein, the extract of the unprocessed plant, which is mixed with the extract of the processed plant, is prepared from a plant different from a plant used to prepare the extract of the processed plant. For example, a cosmetic composition according to a preferred embodiment of the present invention may contain, as active ingredients, an extract of unprocessed peony and extracts of processed Polygonati rhizoma and lily, but the scope of the present invention is not limited thereto.
As used herein, the term “extract of the unprocessed plant” refers to an extract obtained by extracting peony, Polygonati rhizoma or lily with water or an organic solvent, which are conventionally used, without processing the plant.
Hereinafter, the present invention will be described in detail.
Peony which is used in the present invention is a perennial plant belonging to the family Ranunculaceae. It has a single flower blooming at the end of the stem. The flower is large and beautiful and is about 10 cm in diameter in cultivated forms. The flower has various colors, including red and white, and is cultivated in many horticultural varieties. The flower has about 10 petals, particularly 8-13 petals in the case of basic types. The flower petals are about 5 cm in diameter. The stamens are very numerous and yellow, and the pistils are 3-5 in number, with the stigmas turned back. The plant flowers in May to June, and in Chinese medicine, the root is used as a medicine for labor pain, abdominal pain, menstrual pain, amenorrhoea, spitting blood, anemia, bruises and like. In the present invention, in consideration of problems such as difficulty in storage (decomposition) or the quantitative decrease of effective extracts, the peony root is used in a dried form, but the scope of the present invention is not limited thereto.
Polygonati rhizoma which is used in the present invention is the dried root of Polygonatum odoratum, perennial plant belonging to the family Veneridae. In Chinese medicine, the plant is called “Hwang-jung”, “Wi-yu” or “Ok-jook” in Korean. The stem of the plant emerges from the ground and grows to a height of about 30-80 cm. The leaves are alternate on the stem and have an acute tip and a slender edge. The plant is sweet and plain in taste and cold and nontoxic in nature. It acts mainly in the spleen, lungs, stomach and intestines, and the typical components thereof include convallamarin, convallarin, kaempferolglucoside, quercitol, vitamin A, starch and mucus.
Lily which is used in the present invention is a perennial plant belonging to the family Veneridae and grows to a height of 1 m, and the bulb looks like a slightly flattened ball. The leaves are alternate around the stem without a petiole. The flowers bloom sideward or downward in a cluster of 2-3 flowers at the end of the stem in May to June. The flowers usually have fragrance, but some varieties may also have fragrance. In the present invention, in consideration of problems such as difficulty in storage (decomposition) or the quantitative decrease of effective extracts, the lily stem (bulb) is used in a dried form, but the scope of the present invention is not limited thereto.
The cosmetic composition according to the present invention is characterized in that it contains extracts prepared by processing each of peony, Polygonati rhizoma and lily and extracting each of the processed plants with an organic solvent.
Extracts of processed peony, Polygonati rhizoma and lily can be prepared through a method comprising the steps of:
a) adding honey to peony, Polygonati rhizoma or lily and allowing the added honey to be absorbed into the plant for 30 minutes to 1 hour;
b) roasting the plant of step a) at 100-180° C. for 10 minutes to 1 hour; and
c) extracting the roasted peony, Polygonati rhizoma or lily of step b) with water or an organic solvent.
The honey in step a) is added in an amount of 20-30 wt % based on the weight of peony, Polygonati rhizoma or lily used.
The extraction in step c) can be carried out according to any conventional method known in the art. For example, an extract of each of the processed peony, Polygonati rhizoma or lily can be obtained by adding water or an organic solvent to each of the processed peony, Polygonati rhizoma or lily, extracting the plant under reflux in the solvent, dipping the extract in the solvent, filtering the extract through filter cloth, centrifuging the filtered extract to separate it into the residue and the filtrate, and concentrating the separated filtrate under reduced pressure. The organic solvent which is used in the present invention can be selected from the group consisting of ethanol, methanol, butanol, ether, ethyl acetate, chloroform, and mixtures of these solvents with water. Preferably, 80% ethanol is used. Herein, the extraction temperature is preferably 10-80° C., and the extraction time is preferably 6-24 hours. If the extraction temperature and time are out of the above-specified ranges, the extraction efficiency can be reduced or the changes in the components of the extract can occur.
After the extract has been obtained using the solvent as described above, the extract may be macerated at room temperature according to a conventional method known in the art, and the macerated extract may be heated and filtered, thus obtaining a liquid-phase material. Alternatively, the extract may additionally be evaporated to remove the solvent or be spray-dried or freeze-dried.
The cosmetic composition according to the present invention contains one or a mixture of two or more selected from the extracts of the processed peony, Polygonati rhizoma and lily in an amount of 0.0001-30 wt % based on the total weight of the composition. If the content of the extract in the cosmetic composition is less than 0.0001 wt %, the antioxidant effect of the extract cannot be obtained, and if the content exceeds 30 wt %, the increase in the content will not lead to a significant increase in the effect of the extract and it will be difficult to maintain stability or prepare a formulation.
When the mixture of the extracts of the processed peony, Polygonati rhizoma and lily is used, the mixture is preferably contained in an amount of 0.0001-30 wt % based on the total weight of the composition, and each of the components of the mixture may be used in an amount suitably selected from the range of 0.0001 to 30 wt % based on total weight of the composition. Preferably, the extracts of the processed peony, Polygonati rhizoma and lily are used at a weight ratio of 1:1:1.
Also, the cosmetic composition according to the present invention may contain, in addition to the extract of at least one of the processed peony, Polygonati rhizoma and lily, an extract of at least one of unprocessed peony, Polygonati rhizoma and lily.
The extract of unprocessed peony, Polygonati rhizoma or lily is prepared by extracting peony, Polygonati rhizoma or lily with water or an organic solvent without processing the plant, and the preparation process thereof is the same as the above-described extraction process of step c). Herein, the extract of the unprocessed plant, which is mixed with the extract of the processed plant, is prepared from a plant different from a plant used to prepare the extract of the processed plant.
Furthermore, the cosmetic composition according to the present invention contains an extract of at least one of processed peony, Polygonati rhizoma and lily and an extract of at least one of unprocessed peony, Polygonati rhizoma and lily in an amount of 0.0001-30 wt % based on the total weight of the composition. If the content of the extracts in the composition is less than 0.0001 wt %, the antioxidant effect of the extract cannot be obtained, and if the content exceeds 30 wt %, the increase in the content will not lead to a significant increase in the effects of the extracts and it will be difficult to maintain stability or prepare a formulation.
When the mixture of the extract of the processed peony, Polygonati rhizoma or lily with the extract of the unprocessed peony, Polygonati rhizoma or lily is used, the mixture is preferably contained in an amount of 0.0001-30 wt % based on the total weight of the composition, and each of the components of the mixture may be used in an amount suitably selected from the range of 0.0001 to 30 wt % based on the total weight of the composition. Preferably, the extracts of the mixture are used in equal amounts.
The cosmetic composition of the present invention can be formulated as a skin lotion, an astringent lotion, a milk lotion, a nourishing cream, a massage cream, an essence, a pack, a foundation, a lipstick or a powder foundation, but the scope of the present invention is not limited thereto.
In addition, components other than the extract in the cosmetic composition can be suitably selected by a skilled in the art depending on the formulation or intended use of the cosmetic composition.

TEST EXAMPLE 1
Test of Antioxidant Effect (DPPH Test)
To examine the antioxidant effects of the extracts and mixtures thereof prepared in Comparative Examples 1 to 4 and Examples 1 to 10, the antioxidant activities of these extracts and mixtures were evaluated by comparatively measuring the DPPH (1,1-diphenyl-2-picrylhydrazyl) DPPH oxidation inhibitory effects thereof based on the changes in absorbance caused by the reduction of the free radical DPPH (the antioxidant is oxidized). For the extracts obtained in Comparative Examples 1 to 4 and the extracts and mixtures thereof obtained in Examples 1 to 10, the decrease in absorbance caused by the inhibition of oxidation of DPPH compared to the control was measured, and the concentration at which the absorbance was 50% of the control was defined as the effective antioxidant concentration.
10 μl of each of the materials obtained in Comparative Examples 1 to 4 or Examples 1 to 10 and a positive control sample was added to 190 μl of a solution of 100 μM DPPH in ethanol to prepare a reaction solution. The reaction solution was allowed to react at 37° C. for 30 minutes, and then measured for absorbance at 540 nm. As the positive control, the widely used synthetic antioxidant Trolox was used. The results of DPPH analysis of each of the materials are shown in Table 1 below. In Table 1, IC50 means the sample concentration at which the absorbance is reduced by 50%.
