Snippet: Glycyrrhizin (1 g) was mixed with 12 mL hot distilled water and 25% H 2 SO 4 (10 mL) was added dropwise while shaking. The contents were refluxed for 8 h and cooled. The precipitate was filtered under suction and washed till filtrate was neutral to pH paper. The precipitate was dried and crystallized and recrystallized to obtain glycyrrhetic acid (400 mg)......
