Abstract: To study the chemical constituents in the root of Cratoxylum cochinchinense (Loureiro) Blume.The constituents were isolated from C.cochinchinense and purified by TLC,silia gel and gel column chromatography.The structures were identified by physiochemical and spectral data.eleven constituents were elucidated as βsitosterol (1),stignasterl (2),Stigmast4en3one (3),Friedelin (4),Clionasterol (5),ɑMangostin (6),3epibetulinic (7),daucosterol (8),Pruniflorone H (9),(13E,17E)Polypoda7,13,17,21tetraen3bol (10),Vismiaquinone (11).Compounds 5,8,9 and 11 were isolated from the plant for the first time.

Key words: Cratoxylum cochinchinense (Lour.) Blume, friedelin, clionasterol, pruniflorone H, vismiaquinone
