Oligomeric and polymeric procyanidins have been reported to possess different antioxidant capacities. However, the intracellular antioxidant mechanisms of oligomeric and polymeric procyanidins are still poorly understood. In this study, we evaluated the cytoprotective effects of the oligomeric procyanidin fraction (OPF) and the polymeric procyanidin fraction (PPF) from grape seeds against the oxidative...
It is not known if there is a correlation between in vitro and in vivo antioxidant activity of wines. Thus, in the present study, rats were fed with a high-fat diet to induce inflammation and oxidative stress, and received supplementation (1.0mL/day) containing water or three red wine samples characterised by high (41.1mmol TE/L), medium (35.7mmol TE/L) and low (14.4mmol TE/L) in vitro antioxidant...
