Abstract

In this study, in our continuing effort to develop active cosmetic ingredients from natural resource, we continuously screened about Saururus chinensis from South Korea. The alcoholic extract of Saururus chinensis whole and its fractions (separated with Column Chromatography) were evaluated for their effects against Whitening, Anti-wrinkle and Anti-inflammatory. Effect of Tyrosianse, MITF, MMP-1, Tropoelastin and TNF-α exhibited Isoquercetin fraction isolated isolated from Saururus chinensis whole plants. The results of this study suggest that Isoquercetin fraction from Saururus chinensis may be beneficial as whitening, Anti-wrinkle and Anti-inflammatory compound in functional cosmetics resource.
