Supplementary Catechins Attenuate Cooking-Oil-Fumes-Induced Oxidative Stress in Rat Lung
, 2011 Cooking-oil-fumes containing toxic components may induce reactive oxygen species (ROS) to oxidize macromolecules and lead to acute lung injury. Our previous study showed that a decaffineated green tea extract containing ( +)-catechin, (-) -epicatechin, (+

Autoxidation of Catechin [PDF]
Nature, 1955 An exploratory study of those reactions of catechin which lead to polymer formation has enabled the conditions for autoxidation to be defined. The formation of polymers and hydrogen peroxide during the autoxidation at 35 and pH6-8 of catechin and of related 3': 4'-dihydroxyflavans has been studied by measurement of oxygen uptake, and by absorption ...
