Gallic Acid is a phenolic acid with antioxidant activity. Gallic acid was found to protect human cells against oxidative damage and showed cytotoxicity against cancer cells. Gallic Acid and its esters
also show antiviral and antifungal activities.
Gallic acid monohydrate may be used as a standard in the photometric determination of total phenolics content by Folin-Ciocalteu method.
anti-hyperlipoproteinemic, selective, reversible, competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase
Gallic acid monohydrate is a phenolic acid. A study of its crystalline structure reveals that it is planar with two intramolecular hydrogen bonds and five intermolecular hydrogen bonds. Gallic acid is of significant importance because of its antioxidant and anti-cancer activities. Infrared and Raman spectral studies of gallic acid have been reported.
Crystallise gallic from water. The tri-O-acetyl derivative has m 172o (from MeOH), and the anilide has m 207o(from EtOH). [Beilstein 10 H 470, 10 IV 1993.]
