A reinvestigation of the constituents of the Osageorange (maclura pomifera) yielded, in addition to the previously reported triterpenses (lupeol, butyrospermol, and lupan-3beta,20-diol), the pigments osajin and pomiferin, and a previously unreported constituent. The structure of this new compound was investigated. On the basis of spectroscopic and chemical data, it appeared to be an epimer of lupeol
