摘　　要：目的:通过单因素和正交试验法研究五味子种子挥发油最优提取工艺。方法:采用水蒸气蒸馏法,以挥发油得率为指标,以药材粉碎度、料液比、蒸馏时间、浸泡时间4个因素进行正交试验。结果:影响挥发油得率的主要因素为粉碎度,其次为蒸馏时间和料液比,最后为浸泡时间。最佳提取工艺为五味子种子粉碎度60～80目,料液比1∶5,提取8 h,浸泡2 h。结论:该方法提取率高,简单易行,最佳工艺条件下提取率可达到2.72%。Objective：To optimize the extraction condition of volatile oil from seeds of Schisandra chinensis by single factor test and orthogonal test.Method：The experiment was performed with steam distillation,take extraction rate of volatile oil as the index,orthogonal test with the grinding degree of seeds of Schisandra chinensis,solid-liquid ratio,time of distillation and soaking time as affecting factors.Result：The primary factor which influenced the extraction rate was grinding degree,then it was time of distillation,solid-liquid ratio and soaking time.The optimal condition of extraction was as follows：60-80 mesh powder of the grinding degree of seeds ofSchisandra chinensis,1∶5 of solid-liquid ratio,8 h of distillation time,2h of soaking time.Conclusion：The method is efficient,simple and practicable.the extraction rate of volatile oil was 2.72% under the optimal condition.
