A new phenolic sesquiterpene, dysoxyphenol (1), and the known sesquiterpene, 7R,10S-2-hydroxycalamenene (2), were isolated from the acetone extract of Dysoxylum densiflorum seeds. The structures of these compounds were determined based on physical, Nuclear Magnetic Resonance, and mass spectral data.

Five new ring A-seco triterpenoids, dysoxyhainic acids F-J (1-5), along with a known ring A-seco triterpenoid koetjapic acid (6) were isolated from the twigs and leaves of Dysoxylum hainanense. Their structures were established on the basis of extensive spectroscopic analysis. Antimicrobial activity

Two new dammaranes, dysomollisol (1) and dysomollisone (2), along with seven known compounds (3-9) were isolated and identified from the fruits of Dysoxylum mollissimum. The structures of these compounds were determined on the basis of spectroscopic analyses, including 1D and 2D NMR, UV, IR and mass
