ABSTRACT
<p><b>OBJECTIVE</b>To separate and identify the chemical constituents of Blumea riparia.</p><p><b>METHOD</b>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.</p><p><b>RESULT</b>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).</p><p><b>CONCLUSION</b>Compound 1-6 were obtained from B. riparia for the first time.</p>
