description

Abstract The aerial parts of two subspecies of Centaurea aspera L. (Asteraceae) yielded the germacranolides 1a – h , 2 , 3 , 4 and 5 , the elemane derivatives 6d and 6f , the lignan matairesinol, the degraded terpene loliolide, and the onopordopicrin–valine dimeric adduct 7 . From these, compounds 1e , 3 and 6d are natural products. The chemical composition of the two subspecies is very similar, a circumstance which does not support a taxonomic subdivision of the species.
