Abstract:
Six sesquiterpene lactones, two new (3 and 6) and four known (1, 2, 4 and 5) were isolated from the leaves of the Mexican Neurolaena macrocephala (Asteraceae). The furanoheliangolide 6, containing 4beta,5-dihydro-9alpha-hydroxy-atripliciolide as basic structure, was found for the first time in nature. The chemotaxonomic importance of this phytochemical work is discussed.
