title: Delevoyin C, a tetranortriterpenoid from Entandrophragma delevoyi.
abstract: The hexane extract of the bark of Entandrophragma delevoyi has yielded a novel tetranortriterpenoid, delevoyin C. This compound contains a cyclobutanyl ring incorporating C-19 and a cycloheptanyl ring C including C-30. Gedunin and 11beta-Acetoxygedunin were isolated from the hexane extract of the wood.
