Voltammetric Determination of Coenzyme Q10 in a Biologically Active Dietary Supplements (BADSs)
Abstract
A new voltammetric method is developed for quantitative determination of coenzyme Q10 in aqueous media using dc cathodic voltammetry on a glassy carbon electrode in Biologically Active Dietary Supplements. A well-defined reduction peak of coenzyme was obtained at -0.6 V vs. Ag/AgCl. The impact of pH on the redox properties of coenzyme Q10 is considred. The linearity of the calibration curve within the concentration range from 10 to 100 mg/m, provides determination of coenzyme Q10 in BADSs. Metrological characteristics of the developed voltammetric method are calculated. A spectrophotometric determination of coenzyme Q10 in the real samples is used for comparison.
