摘　　要：利用大孔吸附树脂提取甘草中黄酮类化合物,通过正交实验设计得到HP-20型大孔吸附树脂的最佳吸附与解吸条件,甘草提取物中甘草黄酮的最大回收率为7.28%,甘草黄酮的含量为53.5%。通过聚酰胺柱色谱分离后,黄酮的含量可以达到90.26%。测定了HP-20型大孔吸附树脂的动态吸附曲线。Separating licorice flavonoids from glycyrrhiza by HP-20 macroporous resin is studied. Optimal adsorption and desorption condition of HP-20 can be determined through orthogonal design. The highest yield of licorice flavonoids from glycyrrhiza extract is 7.28 % with the content of licorice flavonoids reaching 53.5 %. Through the separation of polyamid chromatograph the content of licorice flavonoids can reach up to 90.26 %. This way the dynamic adsorption curve of HP-20 can be determined.
