EFFECTS OF STRUCTURE ON RADICAL-SCAVENGING ABILTY OF PHENOLS

Abstract

In this study the 2,2-diphenyl-1-picrylhydrazyl radical (DPPH•) was used to explore the contribution of key structural elements of phenolic antioxidants. The presence of a conjugated olefinic double bond and the addition of more hydroxyl groups increased the antioxidant ability of the compounds examined. NMR was also used to follow the reaction between phenolic antioxidants and the DPPH radical and to look at the stoichiometry of the reaction.
