摘要
为了提高枸杞中黄酮类化合物的提取效果,通过超声波细胞粉碎仪的强化作用,对枸杞中的黄酮类化合物进行提取研究,通过单因素和正交试验确定最佳工艺参数。结果表明,最佳提取工艺参数为:乙醇体积分数80%,液料比50 mL/g,超声波工作/间歇时间3 s/1 s,超声波功率500 W,提取时间50 min。在此条件下提取率达到89.87%。
In order to improve the extraction effect of flavonoids from Lycium barbarum L., ultrasonic was used to extract flavonoids of Lycium barbarurn L. Through single fraction experiments and orthogonal experiments, the optimal technological parameters were determined. The result expresses the optimal technological parameters are the concentration of ethanol 80 %, liquid to solid ratio 50 mL/g, ratio of ultrasonic run and interim time 3 s/1 s, ultrasonic power 500 W, extracting 50 min, the extraction rate was 89.87 %
