Phloroglucinol carboxylic acid, also called‘Phloroglucinic acid’ or simply‘PGCA’, is atrihydroxybenzoic acid, a type ofphenolic acid. It can be encountered in nature were it is produced byplants ormicroorganisms. Structurally, the molecule can be perceived asGallic acid in which the 2hydroxy groups at positions 3 and 5 respectively on thebenzene ring backbone have been moved “up” to positions 2 and 6, closely neighboring thecarboxylic acid functional group.Salts andesters of PGCA (e.g.potassium salt ormethyl ester) are known as Phloroglucinates.
It is produced byPseudomonas fluorescens.[1] It is acatechin degradation product excreted by the bacteriumAcinetobacter calcoaceticus, a species of bacteria part of the human body normal flora, grown on catechin as sole source of carbon.[2] It is also found in wine.[3]
