3,4-Dihydroxybenzoic acid is a metabolite of polyphenols such as phloretin and quercetin. It is also a phenolic acid antioxidant present in fruits, vegetables and nuts. Further, it is found to be an efficacious chemopreventive agent in several carcinogenesis models. In addition to this, it acts as an anti-inflammatory agent.
