Self-assembly in saponin mixtures: Escin/tea, tea/glycyrrhizic acid, and escin/glycyrrhizic acid mixtures

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2021
Abstract Saponins are plant based biosurfactants that are obtained from a wide variety of plant species. They are surface active glycosides with a hydrophobic group, which is commonly a triterpenoid or steroidal group, and saccharide hydrophilic units.

Reduction of glycyrrhizic acid

Russian Chemical Bulletin, 1997
The reduction of glycyrrhizic acid by NaBH4 and LiAlH4 was studied. The conditions for the selective reduction of the COOH groups of the carbohydrate chain and the C(11)=0 group of aglycon were found.

Aggregate formation of glycyrrhizic acid

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2016
Abstract Glycyrrhizic acid is derived from the licorice root. The compound is amphiphilic with a large hydrophobic aglycone group, and two glucuronic acids and a carboxyl group constituting the hydrophilic part. Therefore, glycyrrhizic acid can form aggregates or lower the surface tension of aqueous solutions owing to its specific amphiphilic ...

Some properties of glycyrrhizic acid

Chemistry of Natural Compounds, 1994
The chemical and spectral properties of crystalline specimens of glycyrrhizic acid and its monoammonium salt have been studied. On the basis of1H and13C NMR results, diagnostic parameters of the 18β/18α-epimers have been revealed, and features of the structure of the carbohydrate moiety of these compounds are discussed.

Effect of Glycyrrhizic Acid on Lappaconitine Phototransformation

The Journal of Physical Chemistry B, 2007
1H NMR and CIDNP methods were used to demonstrate that triterpene glycoside (glycyrrhizic acid, GA) can substantially change the efficiency and direction of phototransformation of alkaloid lappaconitine (LA) due to both its solubilization in GA micelles and protonation of LA amine nitrogen in water-alcohol solutions.

New Amino-Acid Conjugates of Glycyrrhizic Acid

Chemistry of Natural Compounds, 2014
New conjugates of glycyrrhizic acid (GA) containing two amino-acid methyl esters (4-aminobutanoic, 6-aminohexanoic, 11-aminoundecanoic) were synthesized by the activated-ester method using N-hydroxysuccinimide (HOSu)-N,N′-dicyclohexylcarbodiimide (DCC).

Membrane-modifying activity of glycyrrhizic acid

Russian Chemical Bulletin, 2015
Owing to amphiphilicity, glycyrrhizic acid is capable of forming complexes with a variety of hydrophobic therapeutic compounds. This is accompanied by a significant decrease in the therapeutic dose of the drug. In addition, glycyrrhizic acid has a strong influence on the permeability and elasticity of cell membranes.
