Free Radical Quenching Ability of Anthocyanins

Pelargonidin (Pel) with a mono-hydroxyl group on the B-ring of anthocyanin as a potent inhibitor of tyrosine nitrosylation in vitro scavenged a peroxynitrite (ONOCT). When Pel was reacted with ONOCT, two products were generated and identified as p-hydroxybenzoic acid and 4-hydroxy-3-nitrobenzoic acid by a high-performance liquid chromatography (HPLC). Pel could apparently inhibit the tyrosine nitrosylation by peroxynitrite, a harmful radical species formed via p-hydroxybenzoic acid and 4-hydroxy-3-nitrobenzoic acid [13]. [Pg.7]
