摘　　要：以总黄酮吸附量、解吸量为考察指标进行综合评价，研究了XAD-16型，D101型，AB-8型，HP-20型，NKA-9型，HZ841型这六种大孔树脂和聚酰胺对甘草总黄酮的吸附和解吸的特性。测定了不同树脂对甘草黄酮的静态吸附曲线和解吸曲线，表明所选树脂对甘草黄酮均为快速吸附解吸平衡树脂，吸附2-6h后就可达到吸附平衡，解吸1-3h后就可达到解吸平衡。比较了六种大孔树脂和聚酰胺对甘草总黄酮静态吸附和解吸性能，表明大孔树脂XAD-16对甘草总黄酮具有较好的吸附和解吸陛能，吸附量达到23.97mg／g，解吸率50.69％。Adsorption and the desorption property of seven kinds of resins for Licorice flavone, i.e., XAD-16, D101, AB-8, HP-20, NKA-9, HZ841 and polyamide, were studied in this paper using total flavone content as index. Static adsorption and desorption curves of various resins were studied. It was showed that the selected macroporous resins were all fast-equilibrium resins. Adsorption equilibrium could be reached in 2-4 h, and desorption equilibrium could be reached in about 1-3 h. Macroporous resin XAD-16 was the best for licorice flavone separation for its high adsorption capacity and desorption rate, which were 23.97mg/g resin and 50.69%, respectively.
