Biochemistry coupled with electrochemical approach is employed in a fast, relatively simple, yet highly precise detection of a plant extract antioxidant properties. Antioxidant capacity of dark red corn grains was investigated electrochemically using cyclic voltammetry (CV) on glassy carbon electrode (GC). The linear polarization resistance (LPR) measurements were performed for examining the corrosion inhibitive behavior of polyphenolics on mild steel. The consistent positive correlation (r=0.99) was established between total phenolic and flavonoid contents obtained by CV measurements and spectrophotometric antioxidant assay (DPPH test). Both analyses confirm the high antioxidant activity of tested pigments. Determination of the corrosion inhibition efficiency revealed that the red corn pigments have anti-corrosion effect on mild steels.
