The strong solvation of water to the catechin radical cation may result in the largely negative shift of the one-electron oxidation potential of (+)-catechin, resulting in the acceleration of the initial electron-transfer oxidation of (+)-catechin by galvinoxyl radical.}, pages = {585--588}, title = {Water-Accelerated Radical-Scavenging Reaction of (+)-Catechin in an Aprotic Medium}, volume = {5}, year = {2004} }
