Terpenoids from Dysoxylum densiflorum

Three degraded limonoids, dysodensiols A-C (1-3), and three sesquiterpenoids, dysodensiols D-F (4-6), along with 17 known compounds, were isolated from the twigs and leaves of Dysoxylum densiflorum. The structures of compounds 1-6 were established on the basis of extensive spectroscopic analyses.
