TERPENOIDS FROM THE LEAVES AND STEMS OF DYSOXYLUM TPONGENSE

Study on chemical constituents from the leaves and stems of Dysoxylum tpongense Pierre resulted in the isolation of six known compounds ( 1 – 6 ). The chemical structures of isolated compounds were identified as cabraleahydroxylactone ( 1 ), cabraleahydroxylactone-3-acetate ( 2 ), (+) spathulenol ( 3 ), b -sitosterol ( 4 ), stigmasterol ( 5 ), and stigmast-4-en-3-one ( 6 ) by comparison of the physicochemical, interpretation of NMR and mass spectral data with that reported in the literature.
