摘　　要：通过吸附、解吸实验,筛选适合分离纯化石榴皮多酚的大孔吸附树脂并确立纯化工艺参数。结果表明:HZ-818树脂为石榴皮多酚分离纯化的理想树脂。当提取液上样浓度为2.5 mg/mL,pH为3,上样流速为5 BV/h,洗脱剂浓度为70%乙醇,解吸液流速为2 BV/h,纯化效果最好,其多酚的质量分数由34.0%提高到72.3%。Adsorption and desorption experiments were carried out to screen the suitable macroporous absorbent resin for pomegranate peel polyphenols.Results indicate that macroporous resin HZ-818 possesse the strongest absorbend ability and easier desorption property.The optimum absorption conditions of macroporous resin HZ-818 are concentration of feeding 2.5 mg/mL,pH 3.0,feeding rate 5 BV/h.And the optimum desorption conditions are eluteethanol concentration 70 %,elution rate 2 BV/h,with the polyphenols mass fraction increasing from 34.0 % to 72.3 %.
