The invention mulberry (Morus Disclosed is the use of a new material in functional foods and cosmetics, which is obtained from alba L.) fruit, which is a by-product during the manufacture of audi juices and wines. In other words, to isolate and identify 11 polyphenolic compounds from OD, and to identify their antioxidant activity, the methanol extract of degreasing dioxin foil was degreased with normal-hexane, followed by solvent fractionation with dichloromethane, ethyl acetate and normal-butanol. Among them, ethyl acetate fractions with strong antioxidant activity were subjected to silica-gel, Sephadex LH-20, and ODS-A column chromatography sequentially to purify and purify various polyphenolic compounds, and identify their chemical structure using NMR. And the antioxidant activity was started with the content. |
