Acetylation of the unsaponifiable matter of the petroleum ether extract of the dried fruit yielded a crystalline acetate fraction which was separated by fractional crystallization into lupenyl acetate and a new triterpenyl acetate for which the authors have suggested the name lurenyl acetate. Saponification of lurenyl acetate yielded the crystalline alcohol lurenol. When lurenol was benzoylated, both lurenyl benzoate and lupenyl benzoate were separated from the benzoylation mixture. When lurenol was acetylated, both lurenyl acetate and lupenyl acetate were separated from the acetylation mixture. These isomerizations and the results of analytical data indicate that lurenol is a monohydric triterpenyl alcohol, isomeric with lupeol, and has the molecular formula C30H49OH.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
