| Abstract: | A new triterpenoid named colysanoxide (II) having a novel carbon skeleton has been isolated from the leaves of Colysis elliptica and C. pothifolia, together with α-onoceradiene from the latter. The structure of II was established by spectroscopic, chemical and X-ray diffraction methods. |
