摘 要:研究了树脂柱色谱纯化甘油磷脂酰胆碱(L-α-GPC)的可行性,通过树脂筛选,确定D001大孔阳离子交换树脂为最佳纯化树脂,并对纯化工艺条件进行了优化。通过静态实验得到最优条件:上样质量浓度1.52 mg/mL,样品溶液pH为7,吸附时间300 min,解吸液为去离子水。在静态实验的基础上,进行了树脂柱色谱纯化L-α-GPC的动态实验,对吸附流速、解吸液和解吸流速进行优化。动态实验最优条件:吸附流速2 mL/min,解吸液为去离子水,解吸流速2 mL/min。依据动态实验最优条件,最终L-α-GPC的纯度为96%,回收率为54.1%,这表明树脂柱色谱纯化L-α-GPC的方法是经济、方便、可行的。The feasibility of using resin column chromatography to purify the L-α-glycerylphosphorylcholine(L-α-GPC) was studied.Through the screening of resins,the D001 macroporous cation resin was the best one,and it was used to optimize the purification conditions.Through the static test,the optimal conditions were as follows:the loading concentration 1.52 mg/mL,eluent deionized water,pH of sample solution 7,adsorption time 300 min.On the base of the static test,the dynamic test of the resin column chromatography purifying L-α-GPC was studied,and the conditions of the adsorption flow rate,desorption solution and desorption flow rate were optimized.The dynamic optimal conditions were as follows:adsorption flow rate 2 mL/min,eluent deionized water,elution flow rate 2 mL/min.According to the optimal dynamic test conditions,the purity and recovery of L-α-GPC was 96% and 54.1%,respectively,which indicated that using resin column chromatography to purify L-α-GPC was economic,convenient and practical.
