Abstract:
PURPOSE: A method for preparing secoisolariciresinol is provided to obtain a cosmetic composition having good absorptivity to the user's skin and excellent activity of inhibiting the formation of reactive oxygen species. CONSTITUTION: The method for preparing secoisolariciresinol comprises hydrolyzing flaxseed extract or secoisolariciresinol diglucoside separated therefrom. The hydrolysis is an acidic hydrolysis, alkaline hydrolysis or enzymatic hydrolysis. More particularly, the enzyme used in the enzymatic hydrolysis is selected from the group consisting of exo-glycolases and composite enzymes containing exo-glycolases. Further, the cosmetic composition contains the secoisolariciresinol in an amount of 0.0001 to 10 wt% based on the total weight of the composition.
Abstract:
PURPOSE: Provided is a controlling agent of Bcl-2 expression which characteristically contains ginsenoside F1(20-O-beta-D-glucopyranosyl-20(S)-protopanaxatriol) represented by the formula(1), as an active ingredient. It prevents apoptosis caused by radiating low doses of ultraviolet rays, while promoting apoptosis when radiating high doses of ultraviolet rays, therefore it removes the risk of cancers. CONSTITUTION: A controlling agent of the expression of Bcl-2 is characterized by containing ginsenoside F1(20-O-beta-D-glucopyranosyl-20(S)-protopanaxatriol), which is represented by the formula(1), as an active ingredient. It inhibits the decrease of Bcl-2 expression caused by radiating ultraviolet rays. Therefore, it prevents apoptosis by the radiation of low doses of ultraviolet rays, but promotes apoptosis by the radiation of high doses of ultraviolet rays.
