摘    要:采用超声波萃取法,研究仙人掌黄酮类化合物的提取方法.通过实验确定了乙醇的体积分数、料液比及超声时间的最佳参数.结果表明,乙醇体积分数80%.革取时间20min,料液比为1:10的提取效果最佳;最优条件下提取的黄酮含量为323.81 mg./100g,加标回收率为97.7%.该法与常规溶剂提取法相比,具有提取温度低,产品得率高,氧化损耗小等特点.

关 键 词:黄酮类化合物  超声波  提取  仙人掌

Abstract:Extraction technology of flavonoids from cactus with ultrasonic wave was checked and modified in the study.As a result,the optimal condition were as follows:extraction solvent was 80% ethanol,extraction time was 20 min,ratio of solvent to material was 10:1,the best extrac- tion yield was 323.81 mg/100g.The result showed that this process have value of high yield,low extraction temperature and less time.
Keywords:Flavonoids  Ultrasonic wave  Extraction  Cactus
