摘 要:目的:研究大果大戟Euphorbia wallichii地上部分挥发油的化学成分。方法:采用水蒸气蒸馏法,得到大果大戟挥发油,利用气相色谱-质谱联用技术进行化学成分分析。结果:共分离出25个峰,用面积归一化法测定其相对质量分数,并鉴定出大果大戟地上部分挥发油中20种主要化学成分,已鉴定出的组分占挥发油总量的94.28%。结论:大果大戟地上部分挥发油化学成分包含有机酸、烷烃、萜类及其衍生物,萜类主要为倍半萜,其衍生物则主要为酮类,主要化学成分是十六烷酸(60.36%),其次是降姥鲛-2-酮(7.674%)和十四烷酸(5.433%)。Objective: To study the chemical constituents of the volatile oil from the aerial parts of Euphorbia wallichii.Method: The volatile oil was extracted by steam distillation and was identified by GC-MS.The relative amount of each constituent was calculated by peak area normalization method.Result:Twenty-five components were isolated,20 compounds were identified from the aerial parts of E.wallichii and their amount accounted 94.28% of total volatile oil.Conclusion:Chemical constituents of the volatile oils from the aerial parts of E.wallichii include organic acids,alkane,terpenoids and its derivatives.The main constituents were hexadecanoic acid(60.36%),nor-prist-2-one(7.674%) and tetradecanoic acid(5.433%).
