In this study, licorice root extract was obtained using a multi-stage countercurrent extraction method at bench scale, and the content of glycyrrhizic acid was investigated. The effects of various parameters including temperature, extraction time, number of extraction stages, and solvent-to-solid ratio were evaluated. The optimal extraction conditions were determined using response surface methodology (RSM). Statistical analysis revealed that temperature, time, and number of extraction stages had significant effects on the extraction yield. Under the optimized conditions temperature of 46.17 °C, extraction time of 5.98 hours, solvent-to-solid ratio of 7.70 cc/g, and 4 stages the maximum glycyrrhizic acid extraction yield was 78.7%.
