Journal ArticleDOI
Structure-antioxidant activity relationships of flavonoids and phenolic acids
TL;DR: The factors underlying the influence of the different classes of polyphenols in enhancing their resistance to oxidation are discussed and support the contention that the partition coefficients of the flavonoids as well as their rates of reaction with the relevant radicals define the antioxidant activities in the lipophilic phase.
Journal ArticleDOI
Antioxidant properties of phenolic compounds
TL;DR: It is now possible to establish the antioxidant activities of plant-derived flavonoids in the aqueous and lipophilic phases, and to assess the extent to which the total antioxidant potentials of wine and tea can be accounted for by the activities of individual polyphenols.
Journal ArticleDOI
A Novel Method for Measuring Antioxidant Capacity and its Application to Monitoring the Antioxidant Status in Premature Neonates
Nicholas J. Miller,Catherine Rice-Evans,Michael J. Davies,Vimala Gopinathan,Anthony D Milner +4 more
TL;DR: The method has been applied to investigate the total plasma antioxidant capacity of neonates and how this may be compromised in prematurity, and an antioxidant ranking was established based on their reactivity relative to a 1.0 mmol/l Trolox standard.
Journal ArticleDOI
The relative antioxidant activities of plant-derived polyphenolic flavonoids
TL;DR: The relative antioxidant activities, against radicals generated in the aqueous phase, of a range of plant-derived polyphenolic flavonoids, constituents of fruit, vegetables, tea and wine, have been assessed and compounds such as quercetin and cyanidin have antioxidant potentials four times that of Trolox, the vitamin E analogue.
Journal ArticleDOI
Flavonoids: antioxidants or signalling molecules?
TL;DR: A clear understanding of the mechanisms of action of flavonoids, either as antioxidants or modulators of cell signalling, and the influence of their metabolism on these properties are key to the evaluation of these potent biomolecules as anticancer agents, cardioprotectants, and inhibitors of neurodegeneration.
