Objective To separate and identify the chemical constituents of Blumea riparia DC.Methods The compounds were separated by repeated silica gel,Sephadex LH-20 and HPLC chromatographies.The structures of these isolated compounds were identified by their spectral data and chemical properties.Results Ten compounds were isolated from Blumea riparia DC.and their structures were identified as protocatechuic aldehyde(1),protocatechuic acid(2),p-hydroxybenzaldehyde(3),β-sitosterol(4),stigmasterol(5),kaempferol(6),3,5,3'-trihydroxy-7,4'-dimethoxyflavone(7),3,5,3',4'-tetrahydroxy-7-methoxyflavone(8),quercetin(9),5-hydroxyl-3,7,3',4'-tetramethoxyflavone(10).Conclusions Compounds 3-10 are isolated from Blumea riparia DC.for the first time.
