Objective To study the chemical constituents in the seeds of Euphorbia lathyris.Methods Compounds were isolated by methods of column chromatography(silica gel,including reversed phase),Sephadex,and recrystallization.On the basis of spectroscopic methods including IR,MS,NMR,and X-ray,structures of compounds were confirmed.Results Twenty-two multi-type compounds were isolated from ethanol extract in the seeds of E.lathyris.Their structures were identified as 5,15-O-diacetyl-3-O-phenyl-6(17)-epoxylathyrol(1),5,15-O-diacetyl-3,7-O-dibenzoyl-7-hydroxylathyrol(2),5,15-O-diacetyl-3-O-benzoyl-lathyrol(3),20-O-hexadecanoyl-ingenol(4),3-O-hexadecanoyl-ingenol(5),15,17-O-diacetyl-3-O-cinnamoyl-17-hydroxyjolkinol(6),5,15,17-O-triacetyl-3-O-benzoyl-17-hydroxyisolathyrol(7),5,15-O-diacetyl-3-O-nicotinoyl-lathyrol(8),5,15-O-diacetyl-3-O-benzoyl-7-O-nicotinoyl-7-hydroxy-lathyrol(9),ingenol(10),lathyrol(11),esculetin(12),β-sitosterol(13),benzene-1,2,3-triol(14),palmiticacid(15),2,3-dihydroxypropyl icosanoate(16), 2,3-dihydroxypropyl oleate(17),2,3,4-trihydroxybutyl hexadec-3-enoate(18),aurantianide acetate(19),benzoic acid(20),p-hydroxybenzoic acid(21),oleic acid(22).Conclusion Among these,compounds 10,11,1419 are obtained from this plant for the first time and compounds 1-3 are the main diterpenes
