title: [Studies on the chemical constituents in vine stem of Bauhinia championii (I)].
abstract: OBJECTIVE
  To study the chemical constituents of Bauhinia championii.
  
  
  METHODS
  Compounds were isolated from the ethanolic extract of B. championii by silica gel column Chromatography, and their structures were elucidated by spectral analyses.
  
  
  RESULTS
  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).
  
  
  CONCLUSIONS
  Compounds 1-4 were isolated from B. championii for the first time.
