摘　　要：利用聚酰胺树脂分离纯化马铃薯皮中的总黄酮,通过静态吸附试验和动态吸附试验研究了各因素对黄酮类物质的吸附及解吸附影响。结果表明,静态洗脱过程中,调节pH值为6左右,温度为30℃左右,振荡4 h后静置24 h,并采用浓度为70%乙醇作为洗脱液,即能获得最佳工艺;采用20 g聚酰胺树脂装层析柱的动态洗脱过程中,径高比为2.0/10.0(cm/cm),以70%乙醇作为洗脱液,即能获得动态的最佳工艺。The effectiveness of separation and purification of total flavonoids from potato peel with polyamide resin was studied.Both static adsorption experiments and dynamic adsorption experiments were conducted to study the effects of various factors on the adsorption and desorption of flavonoids.The optimal desorption conditions for static adsorption were determined as being 70% ethanol as desorption solution,pH value at 6,temperature at 30℃,and oscillation for 4 hours following by store for 24 hours.For 20 g of polyamide resin,the optimal desorption conditions for dynamic adsorption were determined as being 70% ethanol as desorption solution,and 2.0/10.0（cm/cm） for diameter to height ratio of the chromatographic column.
