Journal ArticleDOI
Action of Phenolic Derivatives (Acetaminophen, Salicylate, and 5-Aminosalicylate) as Inhibitors of Membrane Lipid Peroxidation and as Peroxyl Radical Scavengers
TL;DR: 5-Aminosalicylate reacts promptly with DPPH, suggesting a potent radical scavenger activity and was found to be the most active in inhibiting Fe2+/ascorbate-induced lipid peroxidation, suggesting an antioxidant activity of chain-breaking type.
Journal ArticleDOI
Antioxidant activities of some extracts of Thymus zygis
TL;DR: There is a relationship between antioxidant potency and the total phenolic groups content in each extract, and Methanolic extracts are more potent as scavengers of peroxyl and superoxide radicals than the ethyl ether extracts.
Journal ArticleDOI
Reactivity of dietary phenolic acids with peroxyl radicals: antioxidant activity upon low density lipoprotein peroxidation
TL;DR: The interaction of four phenolic acids, representative of three chemical groups present in human diet, with peroxyl radicals was studied in vitro in a low density lipoprotein (LDL) oxidation model and the antioxidant activity of the various phenolic compounds is discussed in terms of structure-activity relationships.
Journal ArticleDOI
Two related phenolic antioxidants with opposite effects on vitamin E content in low density lipoproteins oxidized by ferrylmyoglobin: consumption vs regeneration.
TL;DR: Results suggest that caffeic acid acts synergistically with alpha-tocopherol, extending the antioxidant capacity of LDL by recycling alpha-ocopherol from thealpha-tocopheroxyl radical, and p-coumaric acid decreases the peroxidation chain rate.
Journal ArticleDOI
Inhibition of human LDL lipid peroxidation by phenol-rich beverages and their impact on plasma total antioxidant capacity in humans.
TL;DR: Red wine and green tea were the most efficient in protecting low density lipoprotein from oxidation driven by peroxyl and ferril radicals, respectively.
