以花生根白藜芦醇提取液为原料,对选取的5种大孔树脂进行静态吸附试验,确定DA-201树脂为最优吸附树脂.通过DA-201树脂吸附白藜芦醇的动力学试验、DA-201树脂等温吸附试验、上样量试验与动态洗脱试验以及考察上样流速、洗脱流速和洗脱溶剂浓度的三元二次通用旋转组合设计柱层析试验等研究发现:DA-201树脂等温吸附白藜芦醇过程符合Langmuir和Freundilch方程.在上样质量浓度为0.7 mg/mL,上样液pH 3,上样体积为20 mL,洗脱体积为15 mL的条件下,进行DA-201大孔吸附树脂柱层析纯化试验,建立了大孔吸附树脂柱层析纯化白藜芦醇的数学模型.经回归与方差分析,对方程进行局部寻优得出:在上样流速1.00 mL/min...

Taking resveratrol extract from peanut roots periments, DA -201 resin was selected from five resins as th DA - 201 resin adsorption kinetics experiments, a DA - 201 as experimental material and through static adsorption exe optimal adsorption resin for peanut resveratrol. Through resin isothermal adsorption test, a loading volume test, a dynamic desorption test and column chromatography experiments on three factors （loading velocity, eluting velocity and concentration of eluting solvent）, it was concluded that the DA -201 resin adsorption pro...
