The hydrolysates of icariin is prepared by a method comprising the steps of: (a) obtaining an extract from a plant containing icariin using water or an organic solvent; and (b) hydrolyzing the plant extract with an acid, a base, an enzyme or a microorganism producing the enzyme. The cosmetic composition according to the present invention is employed for anti-oxidant, anti-aging, whitening or anti-wrinkling effects.07-02-2009
20100291243EXTRACTOR HAVING POTTERY WITH A DARK BROWN GLAZE AND THE METHOD FOR EXTRACTING USING THEREOF - Disclosed are an extractor having a “pottery with dark brown glaze” called “Onggi” in Korean, and a method of extracting using the same. The extractor includes a body, a body cover, a heating part, a pottery and a gas valve. The pottery is located within the body. The extractor extracts by injecting nitrogen gas, etc. into the body through a gas valve, thereby rendering the inside of the body to be high pressure state during extraction. Thus, the inside of the body is maintained under high pressure during extraction. Accordingly, an extract is located only within the pottery, and thus changes that can be caused while an extract contacts with the body can be prevented.11-18-2010

20080280838Composition Containing Ginsenoside F1 and Egcg for Preventing Skin Damage - The present invention relates to a skin-care composition containing ginsenoside F1 and EGCG. More particularly, the present invention relates to an inhibitor of UV-induced apoptosis in epidermal cells showing an excellent skin-care effect by the synergistic interaction of the said ginsenoside F1 and EGCG even at low concentrations, and to a method for inhibiting apoptosis in epidermal cells.11-13-2008
20080280989Hydroxybenzamide Derivatives, the Method For Preparing Thereof and the Cosmetic Composition Containing the Same - Disclosed is a hydroxybenzamide derivative represented by the following Formula. A method for preparing the same and a cosmetic composition comprising the same are also disclosed. More particularly, the hydroxybenzamide derivative is obtained by reacting a hydroxybenzoic acid having a protecting group introduced thereto with a hydroxyphenyl amine to form a benzamide derivative and by hydrolyzing the benzamide derivative in an aqueous base solution to form a hydroxybenzamide derivative. The cosmetic composition comprising the hydroxybenzamide derivative as an active ingredient has excellent anti-oxidative, anti-aging and skin wrinkle-alleviating effects. wherein R1 represents a C1˜C10 alkyl group, and n is an integer ranging from 1 to 3.11-13-2008
20090131686Sesamol Derivatives or Their Salts, The Process for Preparing the Same, and the Skin External Composition Containing the Same - The present invention relates to a sesamol derivative or its salt, and a skin external composition containing the same. More particularly, the invention relates to a sesamol derivative or its salt, which consists of sesamol and 3-aminopropane phosphoric acid, linked with each other by a phosphoric acid diester bond, and can be degraded into sesamol and 3-aminopropane phosphoric acid by enzymes present on the skin so as to simultaneously show the physiological activities of sesamol and 3-aminopropane phosphoric acid, as well as a preparation method thereof and a skin external composition containing the same.05-21-2009
20090176810COMPOSITION FOR SKIN EXTERNAL APPLICATION CONTAINING GALLOCATECHIN GALLATE FOR MOISTURIZING EFFECT ON THE SKIN - The present invention relates to a composition for external skin application having a skin-moisturizing effect, which comprises gallocatechin gallate as an active ingredient. More particularly, the composition for external skin application comprises gallocatechin gallate as an active ingredient to activate peroxisome proliferator activated receptor isoform alpha (PPAR-α), to stimulate expression of filaggrin and involucrin that are skin-moisturizing factors, and thus to provide excellent anti-drying and skin-moisturizing effects.
