摘要: 通过静态吸附筛选纯化无柄金丝桃茎部总黄酮的最佳树脂,并利用静态吸附解吸动力学确定纯化无柄金丝桃茎部总黄酮的工艺参数。实验结果显示AB8大孔吸附树脂为纯化总黄酮的最佳树脂。最佳工艺参数为:上样液浓度为1.30 mg/mL,体积为60 mL,pH=4.0,流速为1.00 mL/min,树脂柱径高比为1:10,70%乙醇溶液(pH=7.0)为洗脱剂。经AB8树脂纯化,无柄金丝桃茎部总黄酮的纯度由30.26%提高到了55.70%,AB8大孔吸附树脂纯化无柄金丝桃茎部的总黄酮效果明显,其工艺参数简单可行。

Abstract: The optimal macroporous resin for the purification of flavonoids from the stem of Hypericum augustinii N.Robson was screened through static adsorption.The technological parameters of purification process were optimized using static adsorption and desorption kinetics.The results showed that AB8 was the best macroporous resin.The optimal technological parameters were:the concentration of sample solution was 1.30 mg/mL,the sample volume was 60 mL,pH = 4.0 and the flow velocity was 1.00 mL/min.The diameter height ratio of resin column was 1:10,and the elution agents was 70% ethanol (pH = 7.0).The purity of flavonoids from the stem of H.augustinii increased from 30.26% to 55.70% by AB8 macroporous resin.The developed purification process was simple and feasible.

Key words: the stem of Hypericum augustinii N.Robson, flavonoid, macroporous resin
