摘要
在不同溶剂、提取时间、温度、固液比和浸提次数等条件下,通过单因素实验确定正交实验的参数,对新疆紫花苜蓿中黄酮类色素提取最佳工艺条件进行了研究。结果表明,最佳的浸提条件为:浸提剂选用70%乙醇,料液比为1∶50,浸提温度为80℃,浸提时间为4h,浸提次数为2次。
The optimum extraction condition of flavonoids from Medicago sativa L. was studied by means of single factor experiment and orthogonal experimental design. The result showed that the optimum extraction condition was with 60% ethanol concentration, 1：50 material ratio solution, under 80℃, for 4h,twice.
