附子中总生物碱的提取工艺及含量测定

摘要

采用索式回流提取法用乙醇提取附子总生物碱,采用酸碱滴定法测定附子中总生物碱的含量.结果表明,总生物碱的最佳提取工艺:水的倍数为10,时间为1.5h,提取次数为2次.%The total alkaloid was extracted by alcohol via heating backflow extraction method. The content of total alkaloid in aconite was determined. The results indicated the optimal extraction conditions were as follows:extraction times of water 10,time 1.5 h,times 2.
