According to a study published by "Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica", eight compounds were isolated from the ethyl acetate soluble fraction of the ethanolic extract of Bauhinia aurea. These structures were elucidated as isoengeletin (1), astilbin (2), neoastilbin (3), isoastilbin (4), neoisoastilbin (5), (+)-catechin (6), (-)-epicatechin (7) and (-)-epicatechin 3-O-gallate (8). The isolation process involved column chromatography over silica gel, reversed-phase RP-18, and Sephadex LH-20. Five compounds were isolated from this genus for the first time, with the exception of 2, 6 and 8. MS and NMR spectroscopic methods were utilized to determine the structures of the purified compounds.
