Abstract The aerial parts of L. santosii afforded three new diterpenes, a phenylpropanol, three eudesmane derivatives, three germacranolides, seventeen guaianolides and four rearranged guaianolides of a, so far, unknown type. Furthermore, several known compounds were isolated. The structures of the new compounds, the separations of which caused difficulties, were elucidated by spectroscopic methods
摘要 L. santosii 的地上部分提供了三种新的二萜、一种苯丙醇、三种eudesmane 衍生物、三种锗链内酯、十七种愈创木内酯和四种迄今为止未知类型的重排愈创木酚内酯。此外,还分离了几种已知化合物。新化合物的结构,其分离造成困难,通过光谱方法和一些化学转化来阐明。简要讨论了化学分类情况。
