Abstract
Extracts of the stems of Jatropha divaricata have yielded the two new diter penes 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), whi ch appears to be a new skeletal type. The rare cleistanthane diterpenes spr uceanol (1) and cleistanthol (2) were also obtained.
