title: [Two new compounds from Dryopteris fragrans].
abstract: OBJECTIVE
  To study the chemical constituents of Dryopteris fragrans.
  
  
  METHODS
  Two new compounds were isolated and purified from this plant by column chromatography and their structures were elucidated through spectroscopic analysis.
  
  
  RESULTS
  Two new compounds were identified as trans-S-trans-p-hydroxy cinamic acid-9-beta-D-xylpyranosyl (1 --> 2) -beta-D-glucopyranosyl ester, methyl-2-eth-yl-6-((3, 4, 5-trihydroxy-6-(hydroxymethyl) tetrahydro-2H-pyran-2-yl) oxy) benzoate.
  
  
  CONCLUSIONS
  Compounds 1 and 2 are new and named fragranoside J and fragranoside K.
