title: [Studies on the chemical constituents of extract with water from Forsythia suspensa].
abstract: OBJECTIVE
  To study the chemical constituents of the extract with water from Forsythia suspensa.
  
  
  METHODS
  The compounds were isolated and repeatedly purified on TLC, silica gel column chromatograph, gel column chromatography, and preparative HPLC, and the structures were elucidated by physico-chemical properties and NMR.
  
  
  RESULTS
  Eight compounds were obtained and elucidated as stearic acid(I), ursolic acid(II),p-hydroxyphenyl acetic acid(III),3-(4-ehtoxoy-3-hydroxyphenyl)acrylic acid(IV),isolariciresinol(V), epipinoresinol-4-O-beta-D-glucoside(VI),(+)-epipinoresionl(VII),(+)-pinoresinol(VIII).
  
  
  CONCLUSIONS
  Compound III is isolated from this genus for the first time.
