title: [Phenolic derivatives from Wisteria sinensis sweet caulis].
abstract: OBJECTIVE
  To study the phenolic derivatives from Wisteria sinensis.
  
  
  METHODS
  From the petroleum ether extraction of 95% alcohol permeating extraction, 12 compounds were isolated and purified with silica gel and Sephadex LH-20 column chromatography. Their structures were determined on the basis of physicochemical properties and spectroscopic analysis.
  
  
  RESULTS
  They were identified as formononetin (1), (3S)-vestitol (2), (6aS, 11aS)-medicarpin (3), (-+/-) isoduartin (4), (3S)-7,1'-dihydroxy-8,3'-dimethoxyisoflavan (5), isosakuranetin (6), p-hydroxy-benzaldehyde (7), 11b-hydroxy-11b, 1-dihydromedicarpin (8), 3-hydroxy-medicarpin (9), syringaresinol (10), 5-hydroxy-7-methoxychromone (11), vanillin (12).
  
  
  CONCLUSIONS
  All the compounds are isolated from this plant for the first time.
