摘要
以朱砂根根为材料,对朱砂根岩白菜素提取条件进行了较系统的优化筛选试验,结果表明:(1)索氏提取器法提取岩白菜素的优化条件为:提取溶剂为95%乙醇,提取温度为85℃,料液比为1∶11,提取时间为6h,提取次数2次,在此条件下岩白菜素的提取率为2.30%;(2)超声波提取法提取岩白菜素的优化条件为:提取溶剂为95%乙醇,提取功率为50W,提取时间为50min,提取次数为2次,料液比为1∶11,在此条件下岩白菜素的提取率为2.54%。两种提取方法相比,以超声波提取法的提取率为高。
With the root of Ardisia crenata for the testing material, the optimization extraction conditions of bergenin were examined and analyzed systematically in this paper. The results showed that： （1） with the Sohlex method for extraction bergenin, the optimal conditions were as： the concentration of alcohol was 95%, the extraction tempoerature was 85℃, the rate of liquid to powder was 1 ： 12, the extraction time was 6h, then the extraction rate of bergenin was 2.30%; （2） with the Ultrasonic for extraction method, the optimal conditions were as： the concentration of alcohol was 95%, the extraction power was 50W, the extraction time was 50 minutes, and the rate of liquid to powder was I ： 11, then the extraction rate was achieved 2.54%. Then the Ultrasonic extraction method for bergenin in A. crenata was better then Sohlex.
