title: [Study on terpene of Dryopteris fragrans L].
abstract: OBJECTIVE
  To study the terpene of Dryopteris fragrans.
  
  
  METHODS
  Isolation and purification were carried out on repeated silica gel, Sephadex LH-20 column chromatography and prepare HPLC. The structures of the compounds were determined by physicochemical properties and spectral analysis.
  
  
  RESULTS
  Four compounds were isolated and identified as 10-hydroxyl-15-oxo-alpha-cadinol (I), albicany acetate (II), alpha-cadinene (III), albicanol (IV).
  
  
  CONCLUSIONS
  Compounds I is isolated from this plant for the first time.
