摘要：

Three new eudesmane-type sesquiterpene lactones, ent-alpha-cyclodihydrocostupolide, and densilobolide-A and -B, were isolated from the Japanese liverwort Frullania densiloba. Their structures were determined by extensive NMR techniques, chemical degradation and X-ray crystallographic analysis. (C) 1997 Elsevier Science Ltd.
