| 摘 要： | 目的:研究半夏药材中总游离有机酸的最佳提取条件.方法:以电位滴定法为含量测定方法,采用重复-正交试验法,选择乙醇浓度(A)、提取时间(B)、溶剂量(C)、提取次数(D)4个因素,每个因素选取3个水平进行试验,最后确定提取工艺.结果:因素A、B、C、D均对总游离有机酸的含量有极显著的影响.结论:10倍量75%乙醇,加热回流提取2次,每次1 h为半夏中总游离有机酸的最佳提取条件.

| Abstract: | Objective: To optimize the extraction process of total free organic acids in Pinellia ternate Breit. Method: The optimum extraction was investigated by total free organic acids determined by direct potential titration. The concentration of ethanol, amount of ethanol, extraction time and extraction times were the four factors in the experiment. Results: The optimum extraction process was adding 10 times amount of 75% ethanol, refluxing for 2 times, 1h each time. Conclusion: This extraction process shows higher yield of total free organic acids in Pinellia ternate Breit and is available for industrial production. |
