Tea catechins, the most important compounds in tea polyphenols, can efficiently scavenge superoxide anion free-radical (O₂-·), hydroxyl radical. (·OH) The mechanism of scavenging active oxygen free radicals was investigated by ESR spin trapping technique and Chemiluminescence. Results showed that various tea catechins constitute an antioxidant cycle in accordance with the decreasing order of the first reductive potential, and produce the effect of cooperative strength each other. Esterificated… CONTINUE READING
