- Abstract
Extracts of the stems of Jatropha divaricata have yielded the two new diterpenes ent-3 beta,14 alpha-hydroxypimara-7,9(11),15-triene-12-one (3) and the rearranged pimarane ent-15(13-->8)abeo-8 beta(ethyl)pimarane (4), which appears to be a new skeletal type. The rare cleistanthane diterpenes spruceanol (1) and cleistanthol (2) were also obtained.
