Abstract
Four compounds were isolated from the roots of Pimpinella thellungiana Wolff., their structures were identified as palmitic acid(I), 4-propenylphenol(II), pinoresinol(III), 2-methyl-2-hydroxy-5-methoxy berzo(d) hydrofuran-3-one(IV) by physicochemical constants and spectral analysis (UV, IR, MS, 1HNMR, 13CNMR, 13C-1HCOSY, DEPT), IV of them is a new compound, Pharmacological tests showed IV has a hypotensive effect.
