摘要
以秦皮甲素和秦皮乙素的含量为指标,研究了3种微波萃取秦皮的方法.3种方法分别为家用微波炉连续引入溶剂萃取法、微波谐振腔连续引入溶剂萃取法和实验室专用微波炉萃取法.结果表明,溶剂浓度、辐射时间、微波功率、样品粒度等均对萃取有影响.3种微波萃取法与索氏萃取法相比,提取效率高且可省时节能.
With the contents of aesculin and aesculetin as the technical specifications, three microwave-assisted extraction(MAE) procedures were studied. The first procedure is household microwave oven dynamic extraction. The second procedure is microwave resonant cavity dynamic extraction. The third procedure is special microwave oven extraction. The results obtained by the three microwave-assisted extraction procedures were compared with those obtained by using the traditional Soxhlet extraction. And at the same time the results obtained by the three procedures of MAE were also compared with each other. The results indicate that the MAE not only takes a shorter time, but also makes a higher yield of the extraction.
