Glycyrrhizic acid is an important monomeric active ingredient in licorice flavonoids, with various pharmacological effects such as antioxidant, anti ulcer, and anti HIV.
Glycyrrhizic acid is a white powder that is easily soluble in methanol and almost insoluble in ether, originating from licorice.
When used as a sweetener or enhancer, it is generally mixed with other sweeteners.
