Protocatechuic acid (PCA) is 3,4-dihydroxybenzoic acid. It is a simple phenolic acid, which is a precursor for the synthesis of other complex molecules, such as anthocyanin 3-o- β- D-glucoside and vanillin. It is found in edible vegetables, fruits, nuts, brown rice, pecans, tea, hibiscus flowers and some Chinese herbal medicines.
Protocatechuic acid has a variety of biological activities against different molecular targets. It has antibacterial, antioxidant, anti-inflammatory, anti-hyperglycemic and neuroprotective effects. In addition, protocatechuic acid has potential chemical protective effects. It can inhibit chemical carcinogens in vitro and produce apoptosis-promoting and anti-proliferation effects in different aspects. Therefore, it is currently used in the clinical treatment of burns, pediatric pneumonia, bacillary dysentery, acute pyelonephritis, acute pancreatitis and some ulcer diseases.
Protocatechuic acid is used as a dye, intermediate of medicine and analytical reagent (iron determination). Protocatechuic acid can be used to study the effects of 4-coumaric acid and 3,4-dihydroxybenzoic acid on basic oxidative DNA damage in the colon mucosa of rats in vivo. It can be used for the derivatization of chitosan resin.
