title: [Studies on chemical constituents of Peucedanum delavayi].
abstract: OBJECTIVE
  To study the chemical constituents of the radix and rhizome of Peucedanum delavayi.
  
  
  METHODS
  The chemical constituents had been separated by manifold chromato-graphy methods, and their structures were determined by spectral analysis.
  
  
  RESULTS
  Fifteen compounds were isolated and identified as Umbelliferone(I), Coumurayin(II), Mexoticin(III), Marmesin (IV), Ammijin(V), Delton (VI), Selinidin(VII), Anomalin(VII), Isopteryxin(IX), Ferulic acid(X), Falcarindiol(XI), Stearic acid(XII), beta-sitosterol(X III), Daucosterol(XIV) and d-Mannitol(XV).
  
  
  CONCLUSIONS
  All these compounds are isolated from Peucedanum delavayi for the first time.
