Standardized Methods for the Determination of Antioxidant Capacity and Phenolics in Foods and Dietary Supplements
TL;DR: Methods available for the measurement of antioxidant capacity are reviewed, presenting the general chemistry underlying the assays, the types of molecules detected, and the most important advantages and shortcomings of each method.
Journal ArticleDOI
Phenolics and polyphenolics in foods, beverages and spices: Antioxidant activity and health effects – A review
TL;DR: A review of phenolic and polyphenolic compounds can be found in this article, which summarizes both the synthetic and natural phenolic antioxidants, emphasizing their mode of action, health effects, degradation products and toxicology.

The effect of vitamin E and beta carotene on the incidence of lung cancer and other cancers in male smokers
O.P. Heinonen,D. Albanes +1 more
TL;DR: No reduction in the incidence of lung cancer among male smokers is found after five to eight years of dietary supplementation with alpha-tocopherol or beta carotene, and this trial raises the possibility that these supplements may actually have harmful as well as beneficial effects.
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.

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.
