The determination of flavonoid contents in mulberry and their scavenging effects on superoxide radicals
TLDR
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.About:

Thermal Processing Enhances the Nutritional Value of Tomatoes by Increasing Total Antioxidant Activity
TL;DR: Thermal processing enhanced the nutritional value of tomatoes by increasing the bioaccessible lycopene content and total antioxidant activity and are against the notion that processed fruits and vegetables have lower nutritional value than fresh produce.

TL;DR: In this paper, the authors focus on the extraction of polyphenols from agricultural and industrial wastes, and summarize available data on the factors affecting their antioxidant activity and stability, and, in some cases, the reported major active compounds identified.

Antioxidant activity of apple peels
TL;DR: The high content of phenolic compounds, antioxidant activity, and antiproliferative activity of apple peels indicate that they may impart health benefits when consumed and should be regarded as a valuable source of antioxidants.

TL;DR: Bound phytochemicals could survive stomach and intestinal digestion to reach the colon, and may partly explain the mechanism of grain consumption in the prevention of colon cancer, other digestive cancers, breast cancer, and prostate cancer, which is supported by epidemiological studies.

Superoxide dismutase: Improved assays and an assay applicable to acrylamide gels☆
TL;DR: The staining procedure for localizing superoxide dismutase on polyacrylamide electrophoretograms has been applied to extracts obtained from a variety of sources and could thus be assayed either in crude extracts or in purified protein fractions.

The biology of oxygen radicals
TL;DR: The reactive superoxide radical, O2-, formerly of concern only to radiation chemists and radiobiologists, is now understood to be a normal product of the biological reduction of molecular oxygen.
Journal ArticleDOI
The antioxidants of higher plants
TL;DR: The evidence supports at least a partial antioxidant role in vivo for many classes of plant metabolite, and many other compounds as potential antioxidants can be inferred by their similarity to synthetic antioxidants of related structure.

Hydroxyl radical scavenging activity of flavonoids
TL;DR: The scavenging activity of flavonoids decreases in the order: myricetin > quercetin> rhamnetin > morin > diosmetin > naringenin > apigenin > catechin > 5,7- dihydroxy -3′,4′,5′-trimethoxyflavone > robinin > kaempferol > flavone as discussed by the authors.

On the mechanism of antithrombotic action of flavonoids.
TL;DR: Flavonols are anti-thrombotic because they are selectively bound to mural platelet thrombi and owing to their free radical scavenging properties resuscitate biosynthesis and action of endothelial prostacyclin and EDRF.
