Polyphenols deriving from chalcones: Investigations of redox activities

An investigation is performed on the redox properties of a series of hydroxychalcones, a group of polyphenols abundantly present in plants, by cyclic voltamemetry. Oxidation potentials of the phenolates correspond to species that are very easy to oxidize, lead to the rapid formation of nonradical species, underlining the potential antioxidant properties of these molecules
