摘要
采用溶剂浮选法分离富集葛根中的大豆甙元。考察了浮选溶剂、氮气流速、试液pH、浮选时间及电解质(KCl)等因素对浮选效率的影响,优选出最佳浮选条件;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,前者明显优于后者。
Daidzein in puerariae was separated and concentrated by solvent sublation in this paper. The effects of sublation solvent, such as gas flow rate, pH, sublation time and electrolyte KC1 etc. on sublation efficiency were investigated in detail, and the optimal conditions of solvent sublation were selected. In the optimal conditions, the results of solvent sublation were evaluated. Compared with the solvent extraction, solvent sublation showed the obvious advantages.
