A series of 3′,4′-dihydroxy natural aurones differing in ring A substitution pattern have been studied with regards to their radical scavenging potential in the gas and in the liquid phase (benzene, water) using density functional theory (DFT) and the Becke's 3 Lee Yang Parr functional (B3LYP). Based on O–H bond dissociation enthalpy (BDE) and adiabatic ionization potential (IP) values, all tested...
