摘　　要：通过静态吸附和解吸实验,筛选适合分离纯化花生壳多酚的大孔吸附树脂并确定纯化工艺参数。结果表明,NKA-9型大孔吸附树脂是性能良好的花生壳多酚吸附剂,其最佳吸附条件为:样液pH 6.0,吸附温度35℃,样液初始浓度1.0 mg/mL;最佳解吸条件为:洗脱剂乙醇体积分数95%,洗脱液料比30:1(95%乙醇溶液:大孔吸附树脂,mL/g),洗脱剂pH 6.0。Adsorption and desorption experiments were investigated to screen the suitable macroporous absorbent resin for peanut shell polyphenols. The results indicated that macroporous resin NKA-9 possessed the best adsorption and desorption property. The optimum adsorption conditions of peanut shell polyphenols onto NKA-9 resin were determined as follows： initial concentration of sample solution 1,0 mg/mL, sample pH 6.0, and adsorption at 35 ℃. The optimum desorption conditions were ethanol concentration of 95% （v/v） at pH 6.0 with an amount of 30 mL/g （wet resin）.
