Antioxidant effect of red wine polyphenols on red blood cells.

The protective effect was less apparent when RBCs were incubated with wines containing lower levels of polyphenols. Furthermore, resveratrol and quercetin, well known red wine antioxidants, showed lower antioxidant properties compared with SD95, indicating that interaction between constituents may bring about effects that are not necessarily ...

The Pro-Oxidant Activity of Red Wine Polyphenols Induces ...

The protective effect of dealcoholized red wine on human health has been partially associated with its polyphenolic components, suggesting that the pool of polyphenols, including flavonoids and anthocyanins, can be responsible for the functional effects of this beverage. We hypothesize a new role of red wine polyphenols (RWp) in modulating the antioxidant potential of erythrocytes, protecting ...

The mechanisms by which red wine polyphenols exert their antihypertensive effect appear to be important in the prevention and treatment of cardiovascular disease. CONCLUSION It is evident that polyphenolic compounds possess antithrombic, antioxidant, anti-ischemic, vasorelaxant and anti-hypertensive properties.

Red Wine Antioxidants Bind to Human Lipoproteins and ...

Plant-derived polyphenols may exert beneficial effects on atherosclerosis and cardiovascular diseases, in part, because of their antioxidant properties. In this study we compared the effects of unbound (free) and lipoprotein-associated red wine components on in vitro antioxidant protection of human low-density lipoprotein (LDL). Preincubation of LDL (1 mg protein/mL) with 0−2.5% (v/v) red ...

Influence of Solvent Composition on Antioxidant Potential ...

Solvent composition has a large influence on measured antioxidant potential (AOP) of model polyphenols and red wines with 2,2-diphenyl-1-picrylhydrazyl (DPPH). We have shown that incorporation of aqueous buffer in the assay medium results in higher reactivity of catechin and caftaric acid, which are among major polyphenolic constituents of wines. Consequently, AOPs of red wines determined ...
