五味子种子挥发油提取工艺优选

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%。

Optimum Extraction Technology for Volatile Oil from Seeds of Schisandra chinensis

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 distill...
