Abstract:A new compound was isolated from the ether extract of the root of Pimpinella thellungiana Wolff. The structure was identified on the basis of spectral data (UV, IR, 1H-HMR, 13C-NMR, 1H-1 HCOSY, 1 H-13 CCOSY and MS) as 2- (1-methoxy-2-hydroxy) propyl-4-methoxyphenol and named as thellungianin E.
