摘　　要：通过静态吸附实验研究了AB-8和H103两种大孔吸附树脂对丰城鸡血藤总黄酮的吸附特性,筛选出适合丰城鸡血藤总黄酮分离纯化的树脂,并对其进行了动态吸附特性研究。结果表明,AB-8树脂对丰城鸡血藤总黄酮具有良好的吸附和解吸性能,经AB-8树脂吸附富集后,样品总黄酮含量由7.44%提高至40.61%,刺芒柄花素含量提高了15.7倍。因而,AB-8是良好的吸附分离丰城鸡血藤黄酮类化合物的吸附剂。The adsorption characteristics of total flavones from M. nitida var. hirsutissima on AB-8 and H103 were investigated by static adsorption experiments. It was found that AB-8 resin had excellent adsorption and desorption capacity to the total flavones. The dynamic adsorption characteristics of the total flovones on AB-8 resin were studied. The content of total flavones of the tested sample increased from 7.44% to 40.61%, the content of formononetin increased by 15.7-fold after the adsorption concentrating on the AB-8 resin. Thus, AB-8 resin was a excellent resin for separating the flavonoids from M. nitida var. hirsutissirna.
