中文摘要: 采用水蒸气蒸馏法提取沙芥果实精油，考察提取工艺中提取料液比、浸泡时间和提取时间对精油提取量的影响，在单因素试验的基础上通过正交试验对提取工艺进行优化并利用气相色谱-质谱（gas chromatography-mass spectrometry，GC-MS）法，分析沙芥果实精油的化学组成。结果表明水蒸气蒸馏法提取沙芥果实精油的适宜参数为：料液比1∶7（g/mL），浸泡时间3 h，提取时间3 h，精油提取量为0.90 mL。从提取的沙芥果实精油中鉴定出41种化合物，以烷烃、酸、酯、醇、醚、烯为主，其中相对含量最高的化合物是环十二烷，占10.073%；其次是月桂醇，占6.816%；居第三位的是环十四烷，占3.37%。

Abstract:The essential oil was extracted from Pugionium cornutum (L.)Gaertn.fruit by steam distillation.The effects of the material liquid ratio，soaking time，and extraction time on the yield of the essential oil were tested.Single-factor experimental data were obtained，and the extraction technology was optimized with an orthogonal experiment.The chemical composition of the essential oil was analyzed by gas chromatography-mass spectrometry(GC-MS).The results showed that the optimal extraction condition was as follows:material liquid ratio of 1∶7(g/mL)，soaking time of 3 h，and extraction time of 3 h，the yield of the essential oil was 0.90 mL.The chemical components were analyzed by GC-MS，and 41 compounds were identified from the essential oil，most of which were alkanes，acids，esters，alcohols，ethers，and alkenes.The compounds with the highest content were cyclododecane，accounting for 10.073%，lauryl alcohol，accounting for 6.816%，and cyclotetradecane，accounting for 3.37%.
