Although the antioxidant properties of flavonoids are well documented, it is still unclear whether these effects are dependent on radical scavenging or iron chelating activities. Oxidative stress, a state of excessive reactive oxygen species (ROS) activity, is associated with vascular disease conditions such as hypertension. Both the anti‐ and pro‐oxidant effects of tea catechins have been implicated...
The present studies were carried out to determine the intracellular uptake of (‐)epicatechin by erythrocytes during aging in humans. (‐)Epicatechin uptake was estimated by performing ethyl acetate extraction while the total antioxidant potential of the (‐)epicatechin was estimated in terms of FRAP (ferric reducing ability of plasma) values. A significant (p < 0.001) decrease in (‐)epicatechin uptake...
