Summary:Title screen
A simple, accurate and rapid voltammetric method has been developed for the quantitative determination of coenzyme Q[10]. Studies with direct current voltammetry were carried out using a glassy carbon electrode (GCE) in a phosphate buffer solution (pH 6.86). A well-defined oxidation peak of CoQ[10] was obtained at -0.600 V vs Ag/AgCl. The magnitude of the oxidation peak current has been found to be related to the concentration of the coenzyme over the range of (2.0x10{-5} to 2.0x10{-4} M) (r=0,991). Antioxidant activity of CoQ[10] was investigated.
