Chemical Properties
white to slightly yellow powder
Uses
Ammonium Glycyrrhizinate is used in the synthesis of polyion complex nanocarriers which may act as a template for the design of other negatively charged water-soluble drugs. Particularly for anti-infl
ammatory drugs with which Ammonium Glycyrrhizinate is associated.
Uses
pharmaceutical excipient, GRAS, sweetener
Description
§ 184.1408(a)(1) Licorice (glycyrrhiza) root is the dried and ground
rhizome and root portions of Glycyrrhiza glabra or other species of
glycyrrhiza. Licorice extract is that portion of the licorice root that
is, after maceration, extracted by boiling water. The extract can be
further purified by filtration and by treatment with acids and ethyl
alcohol. Licorice extract is sold as a liquid paste ("block"), or spraydried
powder. (2) Ammoniated glycyrrhizin is prepared from the
water extract of licorice root by acid precipitation followed by neutralization
with dilute ammonia. Monoammonium glycyrrhizinate
(C42H61016NH45H2O ) is prepared from ammoniated glycyrrhizin by
solvent extraction and separation techniques.
Definition
ChEBI: Monoammonium glycyrrhizinate is an organic molecular entity.

Biochem/physiol Actions
Biologically active constituent in the sweet root of Glycyrrhiza species (licorice). Antiviral.
Anticancer Research
Glycyrrhizin (GL) is a saponin-like compound that provides the main sweet flavourfor G. glabra (licorice), and it is commonly used in clinical treatment for itsoutstanding pharmacological action such as antitumour, anti-inflammatory andanti-oxidativeactions (Rebhun et al. 2015; Wu et al. 2015). Cai et al. (2017) triedto evaluate the anticancer properties of GA and GL against TNBC in combinationwith etoposide.
Purification Methods
Crystallise the ammonium salt from glacial acetic acid, then dissolve it in ethanolic ammonia and evaporate. The pentahydrate forms needles from 75% aqueous EtOH, m 212-217o. The free acid crystallises from glacial acetic acid. [Karrer et al. Helv Chim Acta 4 100 1921, Lithgoe & Tripett J Chem Soc 1983, 1987 1950, Beilstein 18 IV 5156.]
