Green tea and its polyphenolic catechins: medicinal uses in cancer and noncancer applications.

TL;DR: Aron et al. as discussed by the authors extracted phenolic polymer material from commercial red wine during fermentation and analyzed its chemical composition to characterize its chemical properties, including phenolic quantity and structure.

TL;DR: Peterson et al. as mentioned in this paper presented a Ph.D. dissertation on food science at the University of Minnesota, Bloomington, Minnesota, USA with a focus on food sciences.

TL;DR: The relative antioxidant activities, against radicals generated in the aqueous phase, of a range of plant-derived polyphenolic flavonoids, constituents of fruit, vegetables, tea and wine, have been assessed and compounds such as quercetin and cyanidin have antioxidant potentials four times that of Trolox, the vitamin E analogue.

TL;DR: In addition to the normal complement of plant cell enzymes, tea leaf contains an active polyphenol oxidase which catalyzes the aerobic oxidation of the catechins when the leaf cell structure is disrupted during black tea manufacture as mentioned in this paper.

TL;DR: The effects of tea and green tea catechins on biomarker of oxidative stress, especially oxidative DNA damage, appear very promising in animal models, but data on biomarkers of in vivo oxidative stress in humans are limited.

TL;DR: Recent advances in understanding the etiology and pathogenesis of PD are reviewed in the hope of developing a more effective therapy that will slow or halt the natural progression of PD.
