title: [Chemical constituents from aerial parts of Fallopia convolvulus].
abstract: OBJECTIVE
  To investigate the chemical constituents in the herbs of Fallopia convolvulus.
  
  
  METHODS
  Its 80% ethanol extract was separated by means of silica gel and Sephadex LH-20 column chromatography to give twelve compounds, whose structures were identified by physicochemical properties and spectroscopic evidence.
  
  
  RESULTS
  Twelve compounds were isolated and identified as: quercetin (1), luteolin (2), chrysoeriol (3), apigenin (4), kaempferol-3-O-beta-D-glucoside (5), quercetin-3-O-rhamnoside (6), N-trans-coumaroyl tyramine (7), loliolide (8), ethylparaben (9), beta-sitosterol (10), daucosterol (11), n-hexadecanoic acid (12).
  
  
  CONCLUSIONS
  All these compounds were isolated firstly from this plant, compounds 6-9 were obtained from this genus for the first time.
