The dimeric catechins dehydrotheasinensin A (2) and theacitrin C (3) were prepared from the oxidation of (-)-epigallocatechin-3-O-gallate (EGCG, 1), and their antioxidant activity was investigated using a chemiluminescence (CL) method in vitro. Both compounds showed significant inhibitory effects on reactive oxygen species (O2-, H2O2 and ?OH) and DNA oxidative damage, with 2 being more potent than 3 and EGCG itself.

Black tea is rich in polyphenols and has been shown to have various health benefits; however, its components have not yet been clarified in detail. Enzymatic oxidation of epigallocatechin-3-O-gallate, the most abundant polyphenol in tea, is thought to con
