(-)-EGCG-3'-O-Me is a catechin derivative. (-)-EGCG-3'-O-Me inhibits lipid oxidation in rapeseed oil by reducing oxygen consumption and protecting linoleic acid and α-linolenic acid from degradation during heating. The antioxidant activity of (-)-EGCG-3'-O-Me in heated rapeseed oil is lower than that of its non-methylated precursor, (-)-epigallocatechin (EGCG) [1].
In Vitro, (-)-EGCG-3'-O-Me (0.5 mM; 36-40 h) has reduced antioxidant activity compared to non-methylated EGCG in protecting canola oil from lipid oxidation at 95°C[1].
