Journal ArticleDOI
The Chemistry behind Antioxidant Capacity Assays
TL;DR: This analysis suggests that the total phenols assay by FCR be used to quantify an antioxidant's reducing capacity and the ORAC assay to quantify peroxyl radical scavenging capacity, to comprehensively study different aspects of antioxidants.
Journal ArticleDOI
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
Development and validation of an improved oxygen radical absorbance capacity assay using fluorescein as the fluorescent probe.
TL;DR: The improved ORAC(FL) assay provides a direct measure of hydrophilic chain-breaking antioxidant capacity against peroxyl radical and demonstrates that fluorescein (FL) is superior to B-phycoerythrin.
Journal ArticleDOI
Antioxidant and prooxidant behavior of flavonoids: structure-activity relationships.
TL;DR: The antioxidant and prooxidant behavior of flavonoids and the related activity-structure relationships were investigated in this study using the oxygen radical absorbance capacity assay.
Journal ArticleDOI
Total Antioxidant Capacity of Fruits
TL;DR: In this article, the total antioxidant activity of 12 fruits and 5 commercial fruit juices was measured using automated oxygen radical absorbance capacity (ORAC) assay, and strawberry had the highest ORAC activity (micromoles of Trolox equivalents per gram).
