摘要: 设计正交实验,采用水浴和超声分别对蜂胶中黄酮类物质的提取方法进行了研究。结果表明:水浴法以25倍原料重的70%乙醇水溶液在75℃浸提1h为最佳,超声法以20倍原料重的75%乙醇水溶液超声20min浸提为最佳,超声法优于水浴法,黄酮提取率高达45.6%。

Abstract: Optimal conditions for the extraction of flavonoids from propolis with water bath and ultrasonic wave were studiedby using orthoganol design. The results showed that the optimal conditions for the extraction with water bath were 75℃,25:1of 70% alcohol solution to propolis weight ratio and extraction for 1h. The optimal conditions with ultrasonic technique were20:1 of 75% alcohol solution to propolis weight ratio and extraction for 20 minutes. So the ultrasonic technique used gave betterresults than water bath in this work. The content of flavonoids in the extraction liquid was as high as 45.5%.
