OBJECTIVE
To evaluate the performance of AB-8 macroporous adsorption resin for adsorption and desorption of flavones in liquorice.
METHODS
The concentration of flavones in liquorice was determined by ultraviolet spectrophotometry, and the adsorption behavior of AB-8 macroporous adsorption resin to flavones in liquorice was examined for the adsorption capacity and the volume of solution loaded.
RESULTS
Optimal adsorption of flavones was achieved with the sample pH of 5, total flavones concentration in the solution of 0.85 mg/ml, sample flow velocity of 3 BV/h, and washing with 60% ethanol at the flow velocity of 3 BV/h.
CONCLUSION
AB-8 macroporous adsorption resin can be well applicable for enrichment of flavones in liquorice.
目的
评价AB-8大孔吸附树脂对甘草中黄酮类化合物的吸附和解吸性能。
方法
采用紫外分光光度法测定甘草中黄酮类化合物的浓度，考察AB-8大孔吸附树脂对甘草中黄酮类化合物的吸附行为，包括吸附量和上样液体积。
结果
样品pH值为5、溶液中总黄酮浓度为0.85mg/ml、样品流速为3BV/h、用60%乙醇以3BV/h的流速洗脱时，黄酮类化合物的吸附效果最佳。
结论
AB-8大孔吸附树脂可很好地用于甘草中黄酮类化合物的富集。
