title: [Studies on the chemical constituents from Cissus pteroclada].
abstract: OBJECTIVE
  To study the chemical constituents of Yao Medicine Cissus pteroclada.
  
  
  METHODS
  The compounds were isolated and purified by column chromatography with silica gel, TLC and recrystallization. Their structures were elucidated on the basis of physicochemical properties and spectra analysis.
  
  
  RESULTS
  Six compounds were isolated and identified as beta-sitosterol (I), bergenin (II), 11-O-galloylbergenin (III), 11-O-(4-hydroxy benzoyl) bergenin (IV), gallic acid (V), daucosterol (VI).
  
  
  CONCLUSIONS
  Compounds III and NIV are obtained from the genus for the first time. All the compounds are isolated from this plant for the first time except the compound II.
