Abstract
The novel spiro-triterpenoid spirocaracolitone, was isolated from a ne wly described genus and species, Ruptiliocarpon caracolito Hammel and Zamora (Lepidobotryaceae), a tree from humid lowland tropical rainfore st in Costa Rica. Spectroscopic methods allowed for the elucidation of fragments of the molecule but only X-ray diffraction yielded the defi nitive structure. Spirocaracolitone has a unique, previously unreporte d CD spiro friedelin skeleton.
