Electroanalytical evaluation of antioxidant activity in monofloral honeys

Abstract

Abstract The objective of this study was to develop an electroanalytical technique for the analysis of antioxidant compounds. Five different samples from five monofloral honeys were used. The electroanalysis experiments were conducted using two different techniques, namely cyclic voltammetry (CV) performed with a scan rate of 50 mV/s and differential pulse voltammetry (DPV) with a pulse amplitude of 50 mV and a scan rate of 10 mV/s. All samples were also analyzed by spectroscopy techniquesusing the 2,2-diphenyl-1-picrylhydrazyl (DPPH) microplate method. The electrochemical index determined using the DPV technique agreed with the spectrometric DPPH measurements. This resultdemonstrates that the electroanalysis method could potentially be utilized for antioxidant analysis of honey samples.
