| Abstract: | Objective:To study the adsorption and desorption behavior of macroporous adsorbption resin AB-8 for glycyrrhizic acid and its effect factors. Methods: The optimum purification conditions were investigated by high performance liquid chromatography and the orthogonal experiments. Results:The optimum conditions were as follows:the flow rate at 1 ml/min,pH at 6.4 ~7. 4 and the solution concentration at 10 mg/ml. Conclusion; AB-8 had a high adsorption capacity for glycyrrizic acid and elution was easy. |
