The composition for inhibiting sebum secretion and obesity comprises 0.0001-10 wt.% of kaempferol obtained by degrading kaempferol glycoside with an acid, a base, an enzyme or an enzyme-producing microorganism, wherein the kaempferol glycoside is isolated from a plant, especially green tea; the acid is hydrochloric acid, sulfuric acid or nitric acid; the base is sodium hydroxide or potassium hydroxide; the enzyme is glucosidase, arabinosidase, rhamnosidase, xylosidase, cellulose, hesperidinase, naringinase, glucuronidase, pectinase, galactosidase or amylogucosidase; and the enzyme-producing microorganism is Aspergillus sp., Bacillus sp., Penicillium sp., Rhizopus sp., Rhizomucor sp., Talaromyces sp., Bifidobacterium sp., Mortierella sp., Cryptococcus sp. or Microbacterium sp.
Abstract:
A cosmetic composition comprising a hydrolysate of icariin is provided to show anti-aging effect and melanogenesis inhibition effect through expression inhibition effect, and whitening effect through improving pigmentation generated by UV, thereby being usefully used as a cosmetic composition or a pharmaceutical composition for anti-aging, whitening and wrinkle improving. The cosmetic composition comprises a hydrolysate of icariin represented by the formula(1), wherein R1 is OH or rhamnopyranose and R2 is OH or glucopyranose, provided that both R1 and R2 are not simultaneously rhamnopyranose and glucopyranose. The hydrolysate of icariin is prepared by extracting a plant using water or an organic solvent to obtain a plant extract and then hydrolyzing the plant extract using an acid, a base, an enzyme or a microorganism producing the enzyme.
