title: [Studies on chemical constituents in roots of Peucedanum praeruptorum].
abstract: OBJECTIVE
  To study the chemical constituents in roots of Peucedanum praeruptorum.
  
  
  METHODS
  The constituents were isolated by column chromatography on silica gel and ODS, and identified by MS spectroscopic methods including NMR and.
  
  
  RESULTS
  Seven compounds, acetylatractylodinol (I), tanshinone II A (II), tanshinone I (III), cis-3', 4'-diisovalerylkhellactone(IV), cis-3',4'-disenecioylkhellactone(V), (+)praeruptorin B(VI), and beta-sitosterol(V), were isolated and identified.
  
  
  CONCLUSIONS
  Compounds I, II, III, IV were isolated from this plant for the first time.
