Polyphenolic extract association with renin inhibitors in experimental arterial hypertension

Various epidemiological studies have shown an inverse association between the consumption of polyphenols or polyphenol-rich foods and the risk of cardiovascular diseases. The purpose of the study was to emphasize the effects of the association between the renin inhibitor and the polyphenolic extract on biochemical parameters and systolic and diastolic blood pressure. The polyphenols are extracted from isolated and purified vegetable material represented by the mature fruit of the Aronia melanocarpa. The experiment was performed on the arterial hypertension model. In the arterial hypertensive model the cardioprotective effects of the polyphenolic extract from Aronia melanocarpa are represented by the antioxidant, hypocolesterolemiant intervention. Polyphenolic extract from Aronia melanocarpa reduce systolic and diastolic arterial tension values in rats with druginduced hypertension, a phenomenon more pronounced when polyphenols are associated with Aliskiren (renin inhibitor). The combination between the Aliskiren and polyphenolic extract produce superior hypolipidemic and antioxidant effects than in the case of separate administration within experimental arterial hypertension induced in the murine model.
