摘要：

Three sesquiterpene evoninoate alkaloids, hippocrateine I [1], hippoc-rateine II [2], and emarginatine A have been isolated from the root and stem barks of Hippocratea excelsa. Compounds 1 and 2 are new naturally occurring substances. The structure of 1 was unequivocally established by X-ray crystallographic analysis, and the structure of the second new alkaloid was deduced by spectral analysis. © 1990, American Chemical Society.
