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). CONCLUSION: All these compounds are isolated from Peucedanum delavayi for the first time.
