Abstract

Two new sesquiterpene lactones 8alpha-(2',3'-dihydroxy-2'-methylbutanoyl)-15-desoxygoyazensolide and 16alpha-(1',2'-dihydroxy-1'-methylpropyl)-eremantholide have been identified as constituents of Eremanthus argenteus aerial parts. In addition, two known sesquiterpene lactones and three flavonoids were isolated. Their structures were established on the basis of spectroscopic and spectrometric data.
