Hexavalent chromium reduction by gallic acid
Chemosphere, 2021Cr(VI) is widely used in industry and often large quantities have been accidently or due to lack of precautions released at the environment. The presence of high concentrations of Cr(VI) in waste streams causes concern due to its toxicity and solubility. However the Cr(III) is a useful micronutrient in human diet.

Physical Chemistry Chemical Physics, 1999
Using the pulse radiolysis technique, studies on reactions of 3,4,5-trihydroxybenzoic acid [gallic acid (GA)] with radical species generated in water are reported. At pH 6.8 and 9.7, OH radicals react with GA to give an adduct initially with rate constants of the order of 1×1010 d mol-1 s-1.

Enzymatic gallic acid esterification
Biotechnology and Bioengineering, 1985AbstractGallic acid esters of n‐propyl and amyl alcohols have been produced by enzymatic synthesis in organic solvents using immobilized tannase. Studies indicate that maximum esterification of gallic acid occurs with amyl alcohol. The enzyme shows broad alcohol specificity.

Degradation of gallic acid by Aspergillus flavus
Zentralblatt für Mikrobiologie, 1987Aspergillus flavus utilized gallic acid as sole carbon source and increased in presence of glucose and sucrose. The enzymes were inducible in nature and during degradation of gallic acid. 4-carboxy, 2-hydroxy cis, cis-muconic acid and pyruvic acid were detected. The estradiol (meta) fission of gallic acid by A. flavus was postulated.

Anti-Inflammatory Activity of Gallic Acid
Planta Medica, 1992Gallic acid was found to possess antiinflammatory activity towards zymosan-induced acute food pad swelling in mice. In vitro studies on the mode of action of gallic acid revealed that this compound interferes with the functioning of polymorphonuclear leukocytes (PMNs).

Gallic acid (GA) is a naturally occurring compound with valuable antioxidant activity. Its oral bioavailability is limited by its high metabolism and rapid clearance. In this paper, GA was conjugated with two different materials, phosphatidylcholine (PC) and polyamidoamine (PAMAM) dendrimer.

Biological Activity of a Gallic Acid−Gelatin Conjugate
Biomacromolecules, 2010Goal of the present study was the characterization of the biological properties of a gelatin-gallic acid conjugate (Gel-GA) to evaluate its applicability in biomedicine and pharmacy. The macromolecular conjugate was synthesized by free radical grafting reaction between gelatin and gallic acid (GA) to form a covalent conjugate that was found to retain ...
