title: [Isolation and indentification of chemical compounds from Drynaria fortunei].
abstract: OBJECTIVE
  To study the chemical components of Drynaria fortunei.
  
  
  METHODS
  The herbal material was extracted with 75% ethanol. The chemical components were isolated by silica gel and sephadex LH-20 column chromatography. The structures were identified on the basis of chemical and spectroscopic data.
  
  
  RESULTS
  Four compounds were isolated, three of which were identified as (-)-epiafzelechin-3-O-beta-D-allopyranoside, (-)-epiafzelechin and beta-sitosterol.
  
  
  CONCLUSIONS
  (-)-epiafzelechin-3-O-beta-D-allopyranoside, (-)-epiafzelechin were obtained from D. fortunei for the first time.
