title: Isolation and identification of flavonoids components fromPteris vittataL.
abstract: BACKGROUND
  Pteris vittataL. is rich in flavonoids which exhibit different bioactivities. In order to investigate the flavonoids components ofP. vittataL., extracts of the plant were isolated by column chromatography on silica gel and Sephadex LH-20.
  
  
  RESULTS
  Four flavonoids compounds were obtained, the structures were identified as kaempferol (1), quercetin (2), kaempferol-3-O-d-glucopyranoside (3) and rutin (4), respectively, on the basis of NMR spectroscopic analyses.
  
  
  CONCLUSIONS
  Compound3was reported for the first time fromP. vittataL.
