[Abstract]
Five compounds were isolated from the root of Pimpinella thellungiana Wolff. for the first time. On the basis of physico chemical constants and spectral analysis (UV, IR, MS, NMR, DEPT,1H1HCOSY,1H13CCOSY), their structures were identified as 5 methoxy 2 methyl benzofuran(Ⅰ), diacetin(Ⅱ), isovanillin(Ⅲ), palmitic acid (Ⅳ) and oleic acid (Ⅴ). I is a new compound with antihypertensive activity and named thellungianin H. The other four (Ⅱ~Ⅴ) were isolated from this plant for the first time.
