Method For Preparing Kaempferol-3-0-Rutinoside and Composition of Skin External Application Comprising Thereof

摘要

Disclosed is a method for the preparation of kaempferol-3-O-rutinoside and a composition of a skin external application comprising kaempferol-3-O-rutinoside as an active ingredient. The method for isolating kaempferol-3-O-rutinoside through hydrolysis uses an enzyme or microbe that removes the sugar selectively from kaempferol-3-O-rutinoside glycosides in a plant extract. Disclosed also is a composition of a skin external application comprising kaempferol-3-O-rutinoside that prevents skin wrinkle.
