Abstract
OBJECTIVE: To study the chemical constituents of Bauhinia championii. METHOD: Compounds were isolated from the ethanolic extract of B. championii by silica gel column Chromatography, and their structures were elucidated by spectral analyses. RESULT: Five compounds were isolated and elucidated as 2,4,6-trimethoxyphenol 1-O-beta-D-(6'-O-galloyl)-glucopyranoside (1), (+/-)-lyoniresinol (2), daucosterol (3), beta-sitosterol (4) and gallic acid (5). CONCLUSION: Compounds 1-4 were isolated from B. championii for the first time.
