摘要
目的建立茵陈中总香豆素的溶剂浮选分离富集方法。方法考察了浮选溶剂、样品溶液浓度、氮气流速、试液pH值、浮选时间和电解质NaCl对浮选效果的影响,优选出最佳浮选条件。结果对最佳条件下的浮选效果进行了评价,并与溶剂萃取法进行了对照。结论所建方法简便快速,明显优于溶剂萃取法。
Objective An effective method for separating coumarin from Artemisia capillaris by solvent sublation was established. Methods The effects of sublation solvent, the concentration of sample so lution, N2 gas flow rate, pH value of solution, sublation time, and electrolyte NaCl etc. on the sublationefficiency were investigated and the optimal conditions of the solvent sublation were obtained. Results In the optimal conditions, the results of the solvent sublation were evaluated and compared with the solvent extraction. Conclusion The experimental results show that this method is simple and rapid, and the efficiency of coumarin by solvent sublation is far better than that by the solvent extraction.
