title: [Studies on the chemical constituents of rhizoma of Coniogramme japonica].
abstract: OBJECTIVE
  To study the chemical constituents of Rhizoma of Coniogramme japonica.
  
  
  METHODS
  The Rhizome of C. japonica were extracted with ethanol and the chemical constituents were separated by chromatography technique, and their structures were determined by spectral analysis.
  
  
  RESULTS
  Six compounds were isolated and identified as butyl 2-formyl-5-butoxymethyl-1 H-pyrrole-1-butanoate (1), pterolactam (2), 5-hydroxymethylfurfural (3), methyl linoleate (4), trilinolein (5), dehydrovomifoliol (6).
  
  
  CONCLUSIONS
  All compounds are isolated from the genus for the first time, and the compound 1 is a new compound.
