[Studies on chemical constituents of Peucedanum delavayi].

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.
