大孔树脂纯化马兰总三萜工艺研究
Journal of Anhui University of Chinese Medicine(2017)
Abstract
目的 研究大孔树脂纯化马兰总三萜的工艺.方法 以齐墩果酸为对照品,以吸附量和解吸率作为效果评定指标,筛选出对马兰中总三萜纯化效果最好的大孔树脂,并对上样量、上样液浓度、洗脱速率、洗脱乙醇浓度及用量参数进行考察,筛选出最佳工艺条件.结果 HPD-500的吸附量为0.495 5 mg/mL,解吸率为30.47%,效果最佳;最佳上样液浓度:0.02 g/mL;流速:2 mL/min;洗脱剂:70%乙醇;洗脱体积:2倍柱体积.纯化后马兰三萜含量可达到17.81%.结论 HPD-500大孔树脂在所得工艺条件下可以对马兰中总三萜进行较好的纯化.
