摘　　要：目的研究对叶大戟种子油脂成分。方法采用索式提取法提取对叶大戟种子油,气相色谱-质谱联用(GC-MS)法鉴定化学成分,归一化法测定各成分相对含量。结果对叶大戟种子油中共鉴定出10种脂肪酸,其主要脂肪酸成分为棕搁酸5.608%,硬脂酸2.219%,油酸13.857%,亚油酸17.623%,a-亚麻酸50.854%。结论对叶大戟种子因富含人体必须脂肪酸而极具开发价值,尤其是a-亚麻酸和亚油酸占到了对叶大戟种子油的68.477%。Objective To study the fat constituents of the seed of Euphorbia Sororia.Methods The constituents were extracted by Soxhlet extraction method,then separated and identified by gas chromatograph mass spectrometer（GC-MS）.Relative content of each component was determined by area normalization.Results Ten kinds of fatty acid were identified,the primary fatty acid composition of Euphorbia Sororia seed oil were palmitic acid（5.608%）,stearic acid（2.219%）,oleic acid（13.857%）,linoleic acid（17.623%）,a-Linolenic acid（50.854%）.Conclusion Euphorbia Sororia seeds are in great value of development because of the abundant EFA（essential fatty acid）.a-Linolenic acid and Linoleic acid have a 82% of the relative content in EFA from Euphorbia Sororia seeds oil.
