Abstract

Arctolide (I), together with seven other sesquiterpene lactones II, IV-IX, was isolated from aerial parts of Arctotis grandis THUNB. species. Structures, including absolute configuration, have been assigned to the isolated compounds. Compounds VI and VIII were also isolated from Vernonia angusticeps EKM.
