概要
A reinvestigation of the constituents of the Osage orange (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 and is referred to as 19alpha-H-lupeol.
