Cytotoxic Triterpenoid Constituents from Two Plants of the Family Meliaceae

For their interesting structures and significant biological activities, triterpenoids from plants of the family Meliaceae have been the research focus for several years. In our initial screening of the Meliaceae species, the extracts of Aglaia abbreviata C. Y. Wu and Aphanamixis grandifolia Bl exhibited some inhibitory activity against a panel of tumor cell lines. Phytochemical investigations on the two plants afforded six new dammarane-type...
