摘要
目的:优选地榆中鞣质最佳提取工艺。方法:以提取物中总鞣质含量为指标,通过单因素试验研究提取溶剂、料液比、超声提取时间、超声提取次数等四个因素对总鞣质提取率的影响,利用正交试验确定地榆总鞣质最佳提取工艺。结果:地榆鞣质的最佳提取工艺为:12倍量的40%的乙醇,超声提取2次,每次75min。在最佳条件下,提取率为9.113%。结论:该工艺合理可行,重复性好,地榆鞣质的提取率高。
Objective To optimize the extraction process of total tannins in Sanguisorba officinalis L.Methods Using total tannins as the index,the effect factors to extraction rate including solvent,ratio of solid to liquid,ultrasonic extraction time and ultrasonic fre-quency were investigated by single factor test,and the optimal conditions of extraction were obtained by orthogonal test.Result The ex-traction rate of total tannins in Sanguisorba officinalis L.was 9.113% under the optimal extracting conditions ethanol 40%,ratio of material to liquid 1∶12,extraction time 75 min and extracting for 2 times.Conclusion This extraction process is reasonable,feasible, repeatability and high rate of extraction.
