Catechins and Caffeine Inhibit Fat Accumulation in Mice through the Improvement of Hepatic Lipid Metabolism

Journal of Obesity, 2012
To elucidate the inhibiting mechanisms of fat accumulation by catechins, caffeine, and epigallocatechin gallate (EGCG), ICR mice were fed diets containing either 0.3% catechins or 0.1% EGCG and/or 0.05% caffeine for 4 weeks.

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 ...
