Abstract

Cold press oil of Euphorbia lathyris L.seeds was gained by mechanical press.The oil physicochemical indexes were analyzed,the fatty acid composition of the oil was determined with GC-MS computer system,and the amino acid composition of the seeds was analyzed with automatic amino acid instrument.Results: 7 fatty acids in the Euphorbia lathyris L.oil are identified,among which 4 unsaturated fatty acids total accounts for 92.98%,and the main unsaturated fatty acid,oleic acid,accounts for 84.42%.So the cold press oil of Euphorbia lathyris L.seeds is nourishing and is an ideal raw material for biodiesel.More than 17 amino acids are determined in the seed protein,and the main amino acids are glutamic acid(3.576%) and aspartic acid(1.953%).The Euphorbia lathyris L.seed protein possesses a relatively complete amino acid composition,indicating it is a valuable protein resource for medicine use.
