摘　　要：利用NKA-9大孔吸附树脂对元宝枫绿原酸的吸附与洗脱性能进行了研究。测定其静态吸附率为72.30%,静态解吸率为79.74%。吸附时间为6 h,吸附基本达到最大,解吸时间为2 h,解吸基本达到最大。上样液质量浓度为0.26 mg/mL,pH 2.5,吸附效果最佳。乙醇解析液体积分数为30%时,解析率最大。经吸附、解吸和干燥后,产品纯度达到26.62%。The adsorption and desorption performance of macroporous resin NKA 9 to chlorogenic acid was studied. The static adsorption and desorption index of NKA-9 was 72.3 and 79.74%, respectively. The adsorption quantity reached at the maximum value when the 0% adsorption time was 6 hours, and the desorption quantity achieved the maximum value eluted about 2 hours. The optimum conditions for adsorption and desorption was 0. 26 mg/L（pH2.5） sample concentration and 30 % ethanol concentration, respectively. By the optimum conditions, the product purity was achieved at 26.62%.
