The study presented in this paper concerns the extractability of rutin into an aqueous 1-butyl-3-methylimidazolium chloride (BMIM-Cl) solution. The effects of the concentrations of BMIM-Cl, amounts of Flos Sophorae Immaturus (FSI), extraction temperature and time on the rutin yield were examined. Under optimized extraction conditions, the rutin yield obtained by using aqueous BMIM-Cl corresponded to that obtained by using methanol. A newly established extraction method, followed by HPLC with ultraviolet detection, was applied to FSI samples with good recoveries and high repeatability.
本文所呈现的研究涉及芦丁在1-丁基-3-甲基咪唑氯盐（BMIM-Cl）水溶液中的可萃取性。考察了BMIM-Cl浓度、槐米用量、萃取温度和时间对芦丁产率的影响。在优化的萃取条件下，使用BMIM-Cl水溶液获得的芦丁产率与使用甲醇获得的产率相当。一种新建立的萃取方法，随后采用带紫外检测的高效液相色谱法，应用于槐米样品，回收率良好且重复性高。
