摘要：
Two new neurolenin-type sesquiterpene lactones were found in the leaves of Neurolaena macrocephala Sch. Bip. Ex Hemsl. (Asteraceae). These compounds were identified by their NMR spectra as the 8 beta-isobutyryloxy- and 8 beta-(2-methyl)butyryloxy analogs of neurolenin B. Additionally, the known neurolenins B, C and D and the furanoheliangolide 9 alpha-acetoxy-8 beta-isovaleryloxy-calyculatolide were found to be present in this species. (C) 1999 Elsevier Science Ltd.
