摘要
设计正交试验,采用水浴和超声分别对竹叶中黄酮类物质(芦丁)的提取方法进行了研究。结果表明:水浴法以 15倍原料重的75%丙酮水溶液在80℃浸提1h为最佳,超声法以20倍原料重的75%丙酮水溶液超声30 min浸提为最佳,超声法优于水浴法。
Optimal conditions for the extraction of flavonoids from bamboo leaves with water bath and ultra sonic wave were studied by using orthoganol design. The results showed that the optimal conditions for the extraction with water bath was 80℃, 15: 1 of 7. 5% acetone solution to bamboo leaves weight ratio, extraction for 1h and that with ultrasonic technique was 20: 1 of 75% acetone solution to leaves weight ratio, extraction for 30 minutes. So the ultrasonic technique used was better than water bath in this work.
