摘要:

研究大孔树脂纯化花生壳总黄酮的工艺条件,对大孔树脂的种类及其静态吸附、解吸附条件进行初步探讨。通过静态吸附和解吸附的比较,从7种不同型号的大孔吸附树脂中选出AB-8、DM301、NKA-9三种树脂进行静态吸附解吸动力学,发现NKA-9的吸附解吸效果较为稳定,其吸附解吸平衡时间分别为5h和2h。通过单因素试验,NKA-9的最佳吸附条件为35℃、样液pH7.5,样液中花生壳总黄酮初始浓度(0.112±0.02)mg/ml;最佳解吸条件为体积分数90%乙醇作为解吸液、解吸液用量15ml/g湿树脂、解吸液pH8.5。

Abstract:

AB-8, DM301 and NKA-9 resins were screened from 7 types of macroporous resin in terms of adsorption and desorption capacities to total flavonoids from peanut hull for further studies of static adsorption and desorption kinetics. NKA-9 resin was finally chosen for the purification due to better adsorption and desorption performance, whose equilibrium time of adsorption and desorption were 5 and 2 h, respectively. Single factor experiments showed that the optimum purification procedure of total flavonoids from peanut hull was based on adsorption at 35 ℃of sample solution with an initial concentration of 0.112 ± 0.02 mg/ml at pH 7.5, followed by desorption using 90% aqueous ethanol (V/V) at pH 8.5 with an amount of 15 ml/g (wet resin).

Key words: macroporous resin, peanut hull, total flavonoids, purification
