摘要
采用超声波技术,对蜂胶黄酮的提取工艺进行了研究.选择浸泡时间、乙醇浓度、超声处理时间和液料比4个影响因素,进行响应面试验设计.经响应面优化的试验结果表明最佳提取条件为:乙醇浓度为89%,浸泡时间为11h,超声处理时间为13min,料液比为12.
The extraction processing of the flavonoids from propolis by ultrasound_assisted extraction technology has been studied in the paper.Parameters including extraction time,ultrasound time,concentration of ethanol and ratio of ethanol to propolis were choosed to study the influence on the extraction rate of flavonids.The results showed the optimal extraction conditions were:ethanol concentration 89%,extraction time 11 h,ultrasound time 13 min and ratio of propolis to liquid 1∶12 by orthogonal test according to Responds Surface Methodology(RSM).
