Title: [Studies on flavonoids from Blumea riparia].
Abstract: To separate and identify the chemical constituents of Blumea riparia.The compounds were separated and purified by repeated silica gel, Sephadex LH -20 column chromatographiy. The structures of these compounds isolated were identified by analysis of their spectral data, physical and chemical properties.Six flavonoids were isolated from B. riparia. and their structures were identified as eriodictyol-7, 4'-dimethyl ether (1), eriodictyol-7, 3'-dimethyl ether (2), eriodictyol-7-methyl ether (3), quercetin-7, 3', 4'-trimethyl ether (4), tamarixetin (5), rhamnocitrin (6).Compound 1-6 were obtained from B. riparia for the first time.
