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%。
Aim To study the composition of the oil in the leaves of Euphorbia. Methods The chemical constituents of Euphorbia Herba Euphorbiae were extracted by Soxhlet extraction and identified by gas chromatography-mass spectrometry (GC-MS). The relative content of each component was determined by normalization. Results A total of 10 kinds of fatty acids were identified in the oil of Euphorbia. The main fatty acids were palmitic acid 5.608%, stearic acid 2.219%, oleic acid 13.857%, linoleic acid 17.623% and a-linolenic acid 50.854%. Conclusion Euphorbia seed is rich in human essential fatty acids and great value, especially a-linolenic acid and linoleic acid accounted for Euphorbia seed oil 68.477%.
