Anti-aging and redox state regulation effects of A-type proanthocyanidins-rich cranberry concentrate and its comparison with grape seed extract in mice
A-type proanthocyanidin-rich cranberry concentrate has promising anti-aging effect. Cranberry concentrate is capable of improving glutathione peroxidase activity. Grape seed extract is able to increase superoxide dismutase activity. Both products regulate malonaldehyde, monoamine oxidase and 8-isoprostane levels. Neither of products generates any positive effect on catalase activities.
