Abstract

The sesquiterpene lactones erigerolide and britanin have been isolated from the epigeal part of the plantInula aspera Poir. The spatial structure of the erigerolide molecule has been determined by the x-ray structural method. Erigerolide and inuchinenolide C isolated from difference plant materials are identical and are crystalline polymorphs.
