Natural Polyphenols Are Well-Known to Have the Chemical and Physical Qualities That Help
Protect Vital Biomolecules Including Lipids, Proteins, and Nucleic Acids Against Oxidation. Specific
Enzymatic Measurements and Non-Specific Indicators Were Used to Assess the Level of Oxidative Stress In
Experimentally Produced Arterial Hypertension By the Administration of L-Name. Results Demonstrated
The Antioxidant and Protective Effect of Sambucus Nigra Extract on Biochemical Markers and Histological
Changes In Experimental Arterial Hypertension. Glutathione-Peroxidase and Superoxide-Dismutase
Activities Are Markedly Reduced In the Hypertension Group Compared to the Polyphenol-Protected Group.
The Polyphenolic Extract of Sambucus Nigra May Be Useful As a Nutritional Supplement In Chronic
Cardiovascular and Metabolic Illnesses If Its Effects on the Functionality of Endothelial Cells, Such As
Membrane Sensitivity and Intracellular Signalling, Are Understood.
