响应面法优化超声波辅助提取五味子木脂素研究

Optimization of the ultrasonic assisted extaction technique of lignans from Schisandra chinensis (Turcz.)baill with Response Surface Methodology

本研究采用响应面设计和分析方法,优化超声波辅助提取五味子木脂素的工艺。修正超声波提取五味子木脂素的最佳条件为乙醇浓度95%、液固比16:1、超声时间25.5min,五味子木脂素浓度5.16%。

This study adopts response surface methodology and optimization of the ultrasonic assisted extaction technique of lignans from Schisandra chinensis （Turcz.）baill.It is showed that the optimum conditions is 95 % alcohol at ultrasonic power for 25 minutes with solid to liquid ratio 1∶16 .
