Journal ArticleDOI
Antioxidant activity applying an improved ABTS radical cation decolorization assay.
Roberta Re,Nicoletta Pellegrini,Anna R. Proteggente,Ananth S. Pannala,Min Yang,Catherine Rice-Evans +5 more
TL;DR: A method for the screening of antioxidant activity is reported as a decolorization assay applicable to both lipophilic and hydrophilic antioxidants, including flavonoids, hydroxycinnamates, carotenoids, and plasma antioxidants.
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.

Bioactive compounds in foods: their role in the prevention of cardiovascular disease and cancer
Penny M. Kris-Etherton,Kari D Hecker,Andrea Bonanome,Stacie M. Coval,Amy E. Binkoski,Kirsten F Hilpert,Amy E. Griel,Terry D. Etherton +7 more
TL;DR: Many bioactive compounds are extranutritional constituents that typically occur in small quantities in foods and are grouped accordingly as phenolic compounds, including their subcategory, flavonoids as discussed by the authors.
