Abstract

A simple and fast method based on electrochemical measurements was proposed for estimation of total polyphenols using a carbon paste modified electrode. The method was based on catalytic response exhibited by a ruthenium complex [(bpy)2(NH3)RuIII(µ-O)RuIII(NH3)(bpy)2]4+ in presence of gallic acid (GA). Calibration plots using chronoamperometry (CA) showed a linear response for GA concentrations ranging from 6.6×10−6 to 1.9×10−4 mol L−1 with a detection limit of 4.9×10−7 mol L−1. Comparative studies using the official method revealed a good agreement between methods suggesting that the proposed method can be applied for polyphenol estimation without any sample treatment.
