Terpenoids from the leaves and stems of dysoxylum tpongense

Abstract

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), β-sitosterol (4), stigmasterol (5), and stigmast-4-en-3-one (6) by comparison of the physicochemical parameters, the NMR and mass spectral data with those reported in the literature.
