| 摘 要： | 采用磷酸二异辛酯（P204）/正辛醇反胶束液从面包酵母粗提液中萃取还原型谷胱甘肽(GSH)，研究了各种因素对萃取率的影响以及水相pH值和P204浓度与GSH萃取率关系的数学模型。正交实验确定，GSH的最佳萃取条件是水相pH值2.0，K+浓度0.1 mol•L-1，萃取时间15 min，P204浓度0.16 mol•L-1，GSH单次的萃取率为33.1%，2次萃取率达到49.7%。

| Abstract: | he extraction of glutathione (GSH) from distillate of bread yeast with reversed micelles made up of phosphoric acid dioctyl ester (P204) and n-octanol was researched. The effect factors on Extraction rate of GSH were examined. The optimum conditions were confirmed in the orthogonal tests that extraction time is 15 min; pH value in aqueous phase is 2.0; concentration of P204 is 0.16 mol•L-1 and concentration of K+ is 0.1 mol•L-1. The extraction rate of GSH is 33.1% and the twi-extraction rate got 49.7% in the optimum conditions. |
