对甘草中甘草酸的提取进行了研究,考察了助剂对提取率的影响.结果表明,提取的最佳条件为:助剂与甘草的重量之比为0.25∶1,助剂(1)优于助剂(2).在该实验条件下,粗品的提取率可达97%左右.
The extraction of glycyrrhizic acid in licorice was studied, and the effects of additives on the extraction rate were investigated. The results showed that the optimal extraction conditions were as follows: the weight ratio of auxiliary to licorice was 0.25:1, and auxiliary (1) was better than auxiliary (2). Under the experimental conditions, the crude product extraction rate can reach about 97%.
