hohenackeri (Euphordiaceae), in addition to the known 3-epi-lupeol, two new triterpenes glochidone and glochidiol have been isolated and assigned structures I and VIIIa respectively. The stereochemistry of the hydroxyl groups in glochidiol has been determined by the partial synthesis of three of the fourpossiblestereoisomers of the dihydrodiol diacetate (Vd, VId and VIId) which all differ from dihydroglochidiol
