抄録

To elucidate antioxidant mechanism of natural antioxidants, (+) -catechin was reacted with 2, 2'-azobis [2-methylpropanenitrile] under photoirradiation in a mixture of EtOAc/MeOH (99 : 1, vol/vol). The structure of one major reaction product isolated by chromatography was determined based on the UV, IR, MS and NMR spectrum. This product was idetified as the methyl ester derivative of the acrylic acid, produced from (+) -catechin during the lipid peroxidation. The B ring of (+) -catechin was shown to contribute to antioxidative activity and (+) -catechin was noted to trap the methoxide radical generated from methanol.
