Plant-derived phenolics inhibit the accrual of structurally characterised protein and lipid oxidative modifications.
Epidemiological data suggest that plant-derived phenolics beneficial effects include an inhibition of LDL oxidation. After applying a screening method based on 2,4-dinitrophenyl hydrazine-protein carbonyl reaction to 21 different plant-derived phenolic acids, we selected the most antioxidant ones. T...

Epidemiological data suggest that plant-derived phenolics beneficial effects include an inhibition of LDL oxidation.
