摘　　要：通过静态吸附与解吸实验对4种大孔树脂进行筛选,结果表明:D4006型大孔树脂表现出最好的吸附性能与解吸效果,是较好的富集纯化黄连木粕多酚树脂。通过单因素实验,确定D4006树脂的较佳动态吸附条件为黄连木粕多酚液浓度3.50mg/mL,pH4.5,流速1.0mL/min,较佳洗脱条件为乙醇浓度80%,洗脱流速1.0mL/min,洗脱体积4BV。Static absorption and desorption experiments were carried out to screen the suitable resin from 4 types of macroporous absorbent resin for polyphenols from Chinese Pistache meal. Results indicate that macroporous resin D4006 possesse the strongest absorbend ability and easier desorption property, which is a better candidate for purificating polyphenols from Chinese Pistache meal.Through single factor experiments, the optimum absorption conditions of macroporous resin D4006 are concentration of feed 3.5 mg/mL, pH value 3.5, feeding rate 1.0 mL/min and the the optimum desorption conditions are elute-ethanol concentration 80%, elution rate 1.0 mL/min, elute volume 4 BV.
