Gallic acid is a trihydroxybenzoic acid found in many plants as either the free acid or in the esterified form of gallotannins and ellagitannins. It demonstrates antioxidant activity by scavenging 2,2-diphenyl-1-picrylhydrazyl and hydroxyl free radicals with IC50 values of 9.4 and 191 μM, respectively, and inhibiting microsomal lipid peroxidation with an IC50 value of 1.51 μM. Gallic acid is often used as a standard for determining the phenol content of various analytes by the Folin-Ciocalteau assay where results are reported in gallic acid equivalents.
