  • Publication number: 20080280335
    Abstract: Disclosed is a kaempferol preparing method comprising isolating kaempferol from kaempferol glucosides using an acid, a base, an enzyme or a microbe producing the enzyme. More specifically, the method comprises obtaining a plant extract containing kaempferol glycosides from a plant using water or an organic solvent; and hydrolyzing the plant extract using an acid, a base, an enzyme or a microbe producing the enzyme to isolate kaempferol. The kaempferol glycosides comprise camelliaside A or camelliaside B. The plant extract is derived from a seed or leaf of green tea. When using the method of the invention, it is possible to mass-produce kaempferol, which is one of main physiological activating ingredients, from a plant, particularly a seed or leaf of green tea.

  • Publication number: 20080280838
    Abstract: 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.

  • Publication number: 20060160752
    Abstract: There are provided a promoter containing ginsenoside compound K for the production of hyaluronic acid, and more particularly, a new efficacy of 20-O-?-D-glucopyranosyl-20(S)-protopanaxadiol (compound K), a chief metabolite of ginseng saponin, to increase the expression of hyaluronic acid synthase gene in human cell and thereby to promote the production of hyaluronic acid, and an anti-aging agent containing the promoter for the production of hyaluronic acid as an effective ingredient.

  • Publication number: 20030175315
    Abstract: Disclosed herein is nanoemulsion prepared by emulsifying main metabolites of ginseng saponin obtained by conversion of glucose, i.e. compound K (20-O-&bgr;-D-glucopyranosyl-20(S)-protopanaxadiol), ginsenoside F1 (20-O-&bgr;-D-glucopyranosyl-20(S)-protopanaxatriol) and compound Y (20-O-[&agr;-L-arabinopyranosyl(1→6)-&bgr;-D-glucopyranosyl]-20(S)-protopanaxadiol); and admixture thereof, in fine emulsion or liposome with dermotropic emulsifier by nano-emulsification; and having enhanced skin penetration, so to be effective in promoting proliferation of fibroblast and biosynthesis of collagen.
