[Dihydroflavonol glycosides and flavan-3-ols from Bauhinia aurea].
Zhongguo Zhong Yao Za Zhi. 2007 May; 32(9):815-8.ZZ

Abstract

OBJECTIVE

To study the chemical constituents of Bauhinia aurea.

METHOD

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.

RESULT

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).

CONCLUSION

Five compounds were isolated from this genus for the first time except for 2, 6 and 8.
