摘　　要：本文研究了大孔树脂对薯蔓黄酮(FSPV)吸附分离特性。选择8种大孔吸附树脂,比较其对FSPV的吸附率和解吸率,筛选出最佳种类,并对其动力学曲线和动态吸附性能进行了考察。结果表明:AB-8树脂对FSPV有较好的吸附和解吸效果;其吸附FSPV适宜的条件为:上样液浓度06～1.0mg/ml,pH值在4.28左右,上样流速3ml/min;用95%乙醇洗脱时,解吸率达96.78%,4BV洗脱液基本上能将FSPV洗脱下来。AB-8树脂综合性能较好,适合于FSPV的分离纯化。To study the absorption and separation of the macroporous resin for flavonoids from sweet potato vines （FSPV）. Eight types of macroporous resin were selected to compare their performances in absorbing and desorbing FSPV. The optimal type for FSPV was decided, meanwhile, its kinetic curve and dynamic absorbing behavior were studied. Experimental results showed that AB-8 resin possesses higher absorption and desorption capacity. The appropriate adsorption conditions were： the range of the sample concentration was 0.6-1.0mg/ml, pH was 4.28 or so and velocity of flow was 3ml/min .When 95% ethanol was used as eluant, the desorption capacity was 97%, and 4 BV eluant could desorb FSPV basically. AB-8 macroporous resin showed better comprehensive adsorption property. It can be used to purify and separate FSPV.
