Description

Cosmetic composition for improving skin wrinkles and elasticity comprising the extract as a active ingredient {Cosmetic Composition Comprising Calyx Kaki as Active Ingredient for Improving Skin Wrinkle and Elasticity}

 The present invention relates to a composition comprising a teat extract, and more particularly, the present invention relates to a composition for inhibiting elastase and a composition for improving skin wrinkles and elasticity comprising the extract as an active ingredient.

Skin is an organ that covers the body's surface. The skin is largely divided into epidermis and dermis. The epidermis is the outermost of the skin and acts as a protective barrier for internal organs. The epidermis is composed of a stratum corneum, a clear layer, a granule layer, a play layer and a base layer. The dermis serves to nourish the epidermis and form the skin's framework within the skin tissue. The dermis is composed of a papillary layer and a deep reticular layer, which is a place where skin cell proliferation is induced by fibroblast activity. The reticular layer plays a role in maintaining the elasticity of the entire skin, and collagen (collagen) and elastin (elastic fiber) are meshed (Braverman, J. Invest. Dermatol. , 78, 434-443 (1982). )).

Elastic fibers are elastic fibers included in connective tissue and are much more stretchable than collagen fibers included in connective tissue. Elastic fibers provide elasticity to the skin so that the deformed skin can be restored to its original shape by the force applied to the skin.

Elastin is the main component of the elastic fiber is composed of elastin (90%) of the amorphous insoluble protein 90% of the elastic fiber. Elastase is an enzyme that degrades elastin, and the breakdown of elastin by elastase decreases the elasticity of the skin and accelerates the production of wrinkles (Dermatology pp 18, Korean Dermatology Textbook). Committee compilation, Ryeomungak)

Therefore, a method of inhibiting the degradation of elastin by inhibiting the activity of elastase as a method for improving skin wrinkles and elasticity has been reported (Kim In-young et al . , Kor. J. Pharmacogn 33 (4): 364-371 (2002)).

It is effective in relieving vomiting and coughing, and has been used as a medicinal herb in herbal medicine. The main components of the teat include succinic acid, quercetin, kaempferol, neoodiospyrin, oleanolin, ursolic, betulin and doucosterol. (daucosterol) and others are known (International Collation of Traditional and Folk Medicine, pp 125-126, World Scientific (1997)).

The teat extract used in the present invention may be obtained through various methods known in the art, and preferably comprises (a) water, (b) anhydrous or hydrous lower alcohol having 1 to 4 carbon atoms (eg, methanol, Ethanol, propanol, butanol and the like), (c) acetone, (d) ethyl acetate, (e) chloroform or (f) 1,3-butylene glycol. The extraction solvent is more preferably alcohol, most preferably ethanol and methanol. The nipple as the material for extraction can be dried or used as it is, and preferably used by drying. As a drying method, natural drying or a hot air drying method can be used.

Referring to the following specific preparation of the present invention, a method for preparing a teat extract is described as follows: The teat is washed with purified water, dried and then ground. The milled teat fine powder is placed in methanol or ethanol and leached for several days at room temperature. The leachate was recovered by filtering with Whatman filter paper, and re-leached with methanol or ethanol. The releach process is repeated several times and the recovered leachate is concentrated in a vacuum concentrator.

On the other hand, it will be apparent to those skilled in the art that the extract of the present invention can be obtained not only the above-described extraction solvent but also extract extracts having substantially the same effect using other extraction solvents.

Obtained by various additional purification methods, such as, for example, separation using ultrafiltration membranes having a constant molecular weight cut-off value, separation by various chromatography (manufactured for separation according to size, charge, hydrophobicity or affinity). The fraction is also included in the extract of the teat of the present invention.

The teat extract of the present invention may be prepared in powder form by an additional process such as distillation under reduced pressure, freeze drying or spray drying.

According to a preferred embodiment of the present invention, the extract for use in the present invention, after the extraction using the above-mentioned extraction solvent, for further fractionation of the active ingredient, water and organic solvents (eg, hexane, ethyl acetate) And chloroform). Thus, the extract of the present invention is more preferably a water layer fraction and a chloroform layer fraction, and most preferably a chloroform layer fraction.

The present inventors determined the elastase inhibitory effect of the fraction of each solvent by fractionation of the persimmon extract with various solvents, and as a result, it was confirmed that the water layer and the chloroform layer fractions had an excellent elastase inhibitory effect, in particular, chloroform It was confirmed that the layer fraction had the best effect.

From the above fact, it can be seen that the substance having high solubility in chloroform is particularly excellent in elastase inhibitory effect in the extract of the present invention. In addition, fractionation of the extract by the solvent allows removal of unnecessary substances and the use of only essential ingredients.

Referring to the following specific preparation of the present invention, the solvent-specific fractions of the extract of the teat will be described as follows: The teat extract obtained using the extraction solvent was dispersed in purified water and shaken by adding hexane. After the hexane layer and the water layer were sufficiently separated, an upper hexane layer was taken. Hexane was added to the lower layer (water layer) to extract several more times. After all the recovered upper layers were combined, the solvent was removed using a vacuum distillation apparatus. The lower layer (water layer) is reextracted and concentrated in the same manner as above using chloroform and ethyl acetate instead of hexane. Finally, the water layer is distilled under reduced pressure to obtain a water layer fraction.

The teat extract of the present invention has an excellent effect of inhibiting elastase activity. The reticular layer, which plays a role of maintaining the elasticity of the entire skin, is composed of collagen (collagen fiber) and elastin (elastic fiber) in a net shape. The elasticity of the skin is greatly influenced by elastic fibers, which are mainly composed of elastin, and when the elastin of the elastic fibers is decomposed by elastin degrading enzymes, the skin loses elasticity and accelerates wrinkle formation. The teat extract of the present invention inhibits the degradation of elastin by elastinase by inhibiting the elastase activity so that the elastic fiber can perform its function smoothly, and as a result, the elasticity of the skin is maintained and improved and further wrinkles The production of is suppressed and the effect of improving wrinkles is obtained.

On the other hand, the teat extract of the present invention promotes the proliferation of fibroblasts constituting the fibrous connective tissue of the dermis. The proliferative effect of the fibroblasts by the extract of the present invention enables the supply of healthy young cells to the fibrous connective tissues, resulting in the effect of strengthening the fibrous connective tissue of the skin together with the elastase activity of the extract .

According to a preferred embodiment of the present invention, the content of the teat extract is 0.0001 to 15% by weight, preferably 0.001 to 10% by weight and more preferably 0.01 to 5% by weight based on the total composition. If the amount of the extract is less than 0.0001% by weight, there is a problem that the effect does not appear, and when the amount exceeds 15% by weight, there is no significant difference in the effect.
