摘要
以溪黄草多酚为原料,通过静态吸附和解吸实验对10种大孔树脂进行筛选,确定AL-1为最优吸附树脂。通过静态与动态相结合的方法,确立AL-1树脂对溪黄草多酚的最佳吸附/解吸工艺条件。结果表明,溪黄草多酚提取液的最佳吸附条件为:上样总酚质量浓度为520μg/mL,上样液pH为4,吸附流速为0.8mL/min;最佳洗脱条件为:乙醇体积分数80%,流速0.5mL/min。
The adsorption and desorption rates of polyphenols from Rabdosia serra (Maxim.) Hara were used as indexes to compare ten kinds of macroporous resins, and the AL-1 was proved to be the best resin and used to optimize adsorption and desorption conditions of polyphenols from Rabdosia serra (Maxim.) Hara. Results showed that the best adsorption conditions were: loading sample concentration of polyphenols 520 lag/mL, sample pH 4, loading flow rate 0.8 mL/min. The best desorption conditions were: concentration of ethanol 80%, desorption velocity 0.5 mL/min.
