摘要
以长白山柳蒿芽为试材,在单因素试验基础上,采用4因素5水平响应面分析法,研究了超声波-微波提取因素对柳蒿芽黄酮提取率的影响,同时建立最佳提取工艺。结果表明:液料比26∶1mL/g、乙醇体积分数42%、超声波功率538W,酶添加量1.4%,在此条件下柳蒿芽黄酮的提取率为5.42%,与常规水浴法提取柳蒿芽黄酮相比具有更高的提取效率。
Taking Artemisia integrifolia L.as materials,on the basis of single factor experiment,the effect of ultrasonic and microwave factors on flavonoids fromArtemisia integrifolia L.were studied by the response surface methodology with four factors and five levels to determined the optimum technology.The results showed that liquid-material ratio26∶1mL/g,alcohol concentration 42%,ultrasonic power 538 W,and enzyme dosage 1.4%.In these conditions,the extraction rate of Artemisia integrifolia L.flavonoids was 5.42%.The extraction rate of Artemisia integrifolia L.flavonoids by ultrasound-microwave enzyme synergistic method was better than conventional water bath method.
