Petrol extract of the fruits of Diospyros peregrina (Ebenaceae) has afforded a pentacyclic triterpene ketone with a homoannular diene system, besides betulin and lupeol.In order to establish the structure of the ketone, partial synthesis of both olean- and ursan-9(11),12-dien-3-ones have been achieved.The structure of the pentacyclic triterpene ketone has been established as marsformosanone (II) from spectral data, chemical reactions and synthesis.The occurrence of marsformosanone in Marsdenia formosana Masamune has been recently reported .
