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.
