Ferric Reducing Antioxidant Power and Square Wave Voltammetry for Assay of Low Molecular Weight Antioxidants in Blood Plasma: Performance and Comparison of Methods.

Original language description

The purpose of the present study was to employ two methods-square wave voltammetry (SWV) performed on screen printed sensors and ferric reducing antioxidant power (FRAP)- as suitable tools for the assay of low-molecular-weight antioxidants (LMWAs). LMWAswere assayed by both methods and the resulting data were statistically compared. Plasma samples from five Cinereous vultures accidentally intoxicated with lead were used to represent real biological matrices with different levels of LMWAs. Blood was collected from the birds prior to and one month after treatment with Ca-EDTA. SWV resulted in two peaks. The first peak, with the potential value of 466 +- 15 mV was recognized as ascorbic and uric acids, while the second one (743 +- 30 mV) represented glutathione, tocopherol, ascorbic acid and in a minor effect by uric acid, too. Contribution of individual antioxidants was recognized by separate assays of LMWA standards. Correlation between peaks 1 and 2 as well as the sum of the two peaks
