[Study on purification of glycyrrhizic acid with macroporous adsorption resin].


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… (More)
