A Study of the Ionic Liquid-Based Ultrasonic-Assisted Extraction of Isoliquiritigenin from Glycyrrhiza uralensis

Figure 3

(a) The impact of IL type. The following extraction parameters were utilized: 0.4 g of dried sample combined with an IL concentration of 0.3 mol/L was used with a solid-liquid ratio of 1 : 15, a 120 min ultrasonication duration, a temperature of 60°C, and a 100 W ultrasonic power. (b) The impact of IL concentrations. The following extraction parameters were utilized: 0.4 g of dried sample combined with [BMIM]Br aqueous solution was used with a solid-liquid ratio of 1 : 15, a 120 min ultrasonication duration, a temperature of 60°C, and a 100 W ultrasonic power. The different uppercase letters on the bars represent significant differences () between treatments.
