| 摘 要： | 通过总还原能力的测定得出五味子六种标准品中,五味子乙素抗氧化性能最好。利用超声波辅助提取法提取五味子乙素,通过研究得出各因素对五味子乙素提取率的影响程度从大到小的依次顺序为溶剂浓度料液比超声时间,在单因素的基础上,采用二次旋转组合设计及响应面优化,得出五味子乙素的最佳提取工艺为:超声40min,料液比1:10,乙醇浓度为90%,五味子乙素提取率为2.11mg.g-1。

| Abstract: | Result of the Frap text showed that Schisandrin B has the strongest antioxdant activity.The extraction of Schisandrin B from fructus schisandrae chinensis by Ultrasonic was studied.Results showed that the effects of various factors on the extraction ratio was as the following order：ethanol concentration the ratio of solid to liquid ultrasonic time.Base on the results of single-factor experiment,by using the method of orthogonal rotation combination test and response surface test,the optimal conditions were as follow：ultrasonic time 40 min;ethanol concentration 90% ;the ratio of solid to liquid 1：10.On these conditions the yield of Schisandrin B can reach 2.11 mg.g-1. |
