ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents of Bauhinia aurea.</p><p><b>METHOD</b>The compounds were isolated by column chromatography over silica gel, reversed-phase RP-18, and Sephadex LH -20. MS and NMR spectroscopic methods were used to determine structures of purified compounds.</p><p><b>RESULT</b>Eight compounds were isolated from the ethyl acetate soluble fraction of the ethanolic extract and their structures were elucidated as isoengeletin (1), astilbin (2), neoastilbin (3), isoastilbin (4), neoisoastilbin (5), (+)-catechin (6), (-)-epicatechin (7) and (-)-epicatechin 3-O-gallate (8).</p><p><b>CONCLUSION</b>Five compounds were isolated from this genus for the first time except for 2, 6 and 8.</p>
