Protocatechuic acid (PCA) is 3,4-dihydroxybenzoic acid. is a simple phenolic acid that 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 herbs.
Protocatechuic acid has a variety of biological activities against different molecular targets, and it has antibacterial, antioxidant, anti-inflammatory, anti-hyperglycemic and neuroprotective effects. In addition, protocatechuic acid has potential chemical protective effects. It inhibits chemical carcinogens in vitro and produces pro-apoptotic and anti-proliferative effects in various ways. Therefore, it is currently used clinically for the treatment of burns, infantile pneumonia, bacillary dysentery, acute pyelonephritis, acute pancreatitis and some ulcer diseases.
