- Abstract
- The antioxidative activity of the extracts from amaranth flower and leaves was characterized using 1,1-diphenyl-2-picrylhydrazyl (DPPH) method and cyclic voltammetry. It was found that the extracts prepared with amaranth flower (AM-F) showed an improved antioxidative activity compared to the extracts prepared with amaranth leaves (AM-L) using the conventional DPPH method. Furthermore, the antioxidative activities of AM-F and AM-L were evaluated using cyclic voltammetry as an electrochemical method. AM-F exhibited an improved electrochemical oxidation for active oxygen and a fast removal of active oxygen compared to AM-L. In addition, the CV analysis to evaluate antioxidant activity was found to be more accurate, compared to DPPH method. (C) The Electrochemical Society of Japan, All rights reserved.
