Upgrading of grape skins: Significance of plant cell-wall structural components and extraction techniques for phenol release
TL;DR: In this paper, an in-depth knowledge of how phenols are bound in grape skins will allow us to employ the most suitable techniques to release phenols in order to optimize the phenol-related properties of wine and maximize the recovery from grape byproducts.

Salinity effects on polyphenol content and antioxidant activities in leaves of the halophyte Cakile maritima.
TL;DR: It is suggested that halophytes may be interesting for production of antioxidant compounds, and that the accession-dependent capacity to induce antioxidative mechanisms in response to salt, may result in a corresponding variability for growth sustainability.

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).
