## Abstract A kinetic study of the reduction of pyrocatechol and catechin by dpph^β’^ radical has been carried out in various ratios of CH~3~OH/H~2~O mixed solvent at pH 5.5β7.5, ΞΌ = 0.10 M [(__n__βBu)~4~N]ClO~4~, and __T__ = 25Β°C. The rate constants of oxidation in aqueous solvent, __k__, were obta
