3、resin is filtered as the optimal resin to extract purified glycyrrhizic acid from the six kinds of resins. The study of pH, supernatant flow rate, supernatant concentration, eluent concentration and eluent amount shows t

4、hese five factors effects on the adsorption and desorption of glycyrrhizic acid, and optimum conditions were investigated by orthogonal experiment. Experimental results showed that the optimum adsorption conditions as fo

5、llows: pH 6.0, supernatant flow rate for 2BV/h, the concentration of the supernatant for 10mg/ml; best desorption conditions were as follows: 10% ethanol, eluent amount for 234ml. Under optimal conditions droved by exper

6、iment, the purity of glycyrrhizic acid was 65.07%, recovery rate was 65.3%. In addition, we completed the structural conversion of glycyrrhizic acid under a condition of sodium hydroxide's reflux; results showed that
