four Schistostephium species, in addition to known compounds, 43 new ones were isolated, three isocomene, two bisabolene, two eudesmane, two allo-himachalene and two nerolidol derivatives, two sesquiterpenes with a new carbon skeleton derived from isocomene, nine eudesmanolides, 20 6,12- and 8,12-germacranolides respectively, and a prostaglandin-like acid. The structures were elucidated by spectroscopic
摘要 从四种血吸虫属物种中,除已知化合物外,还分离出 43 种新化合物,三种异科烯、两种红没药烯、两种桉树烯、两种异喜马查烯和两种橙花油衍生物、两种具有源自异丁烯的新碳骨架的倍半萜、九种eudesmanolides、分别为 20 6,12- 和 8,12-germacranolides,以及一种前列腺素样酸。通过光谱方法,尤其是高场 1 H NMR 和一些化学转化方法阐明了结构。一些 8,12-germacranolide 的立体化学是通过部分合成建立的,这需要修改之前对犬内酯、其 4,5- 和 1,10-环氧化物、vernudifloride、simsiolide、6-hydroxy-1,10 构型的分配-epoxyinunolide,也许还有 tanachin。简要讨论了化学分类情况。
