TLDR
In this article, the authors examined the in vitro radical scavenging and antioxidant capacity of tannic acid by using different in vitro analytical methodologies such as 1,1-diphenyl-2-picryl-hydrazyl free radical (DPPH ) scavenging, 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) activity, total antioxidant activity determination by ferric thiocyanate, total reducing ability determination using by Fe3+−Fe2+ transformationAbout:

Superoxide Ion: Generation and Chemical Implications
TL;DR: This review comprises the main characteristics of O2(•-) followed by generation methods, and its potential applications including the destruction of hazardous chemicals, synthesis of organic compounds, and many other applications are highlighted.
Journal ArticleDOI
Antioxidant activity of food constituents: an overview
TL;DR: The most commonly methods used in vitro determination of antioxidant capacity of food constituents are reviewed and presented, and the general chemistry underlying the assays in the present paper was clarified.
Journal ArticleDOI
Antioxidants and antioxidant methods: an updated overview
TL;DR: Antioxidants had a growing interest owing to their protective roles in food and pharmaceutical products against oxidative deterioration and in the body and against oxidative stress-mediated pathological processes as discussed by the authors, and many studies evaluating the antioxidant activity of various samples of research interest have been conducted.
Journal ArticleDOI
Polyphenols: Extraction Methods, Antioxidative Action, Bioavailability and Anticarcinogenic Effects
TL;DR: One of the promising solutions lies in nanoformulation of polyphenols that prevents their degradation and thus enables significantly higher concentrations to reach the target cells, resulting in lowering of the required therapeutic dose and in multitargeted action.

The determination of flavonoid contents in mulberry and their scavenging effects on superoxide radicals
TL;DR: In this article, it was shown that mulberry leaves contain at least four flavonoids, two of which are rutin and quercetin, and that the scavenging effects of most mulberry extracts were greater than those of rutins (52.0%) at a concentration of 5μg ml −1.
