Abstract: Five compounds were isolated from the seeds of Dysoxylum cauliflorum and their structures were elucidated as β-sitosterol (1), ethyl gallate (2), daucosterol (3), 1-O-β-D-glucopyranosyl-(2S,3S,4R,8Z)-2-N-(2′-hydroxytetracosanoyl) octadecasphinga-8-ene (4), and 2,3,2″,3″-tetrahydroamentoflavone (5). All of these compounds were isolated from this plant for the first time. Compound 5 was evaluated for cytotoxicity against five human cancer cell lines but showed no inhibitory activities.

Key words: Dysoxylum cauliflorum, Meliaceae, 2,3,2″,3″-tetrahydroamentoflavone, cytotoxicity
