Peroxidase-based biosensor as a tool for a fast evaluation of antioxidant capacity of tea
(Elsevier Sci LtdOxfordInglaterra, 2005)
Relation between polyphenol profile and antioxidant capacity of different Argentinean wheat varieties. A boosted regression trees study
(Elsevier, 2017-03)
We report the polyphenol profile and antioxidant capacity (AC) of 12 Argentinean wheat varieties from different regions. The polyphenol profile was studied by HPLC–MS. The AC was measured by TEAC and FRAP. Twenty-five ...
Modified CUPRAC spectrophotometric quantification of total polyphenol content in beer samples using Cu(II)/neocuproine complexes
(ACADEMIC PRESS INC ELSEVIER SCIENCESAN DIEGO, 2012)
Cu(II)/neocuproine (2,9-dimethyl-1,10-phenanthroline) complexes were utilized for spectrophotometric determination of total polyphenol content in beers. This procedure is based on the reduction of Cu(II) by polyphenols in ...
Hepatocellular carcinoma and miRNAs: An in silico approach revealing potential therapeutic targets for polyphenols
(2022-05-01)
Background: Identifying innovative and effective therapeutic agents is imperative for treating hepatocellular carcinoma (HCC). Natural phytochemical compounds may be a feasible glimmer of hope as more than 8,000 phenolic ...
Polyphenolic cells and their interrelation with cotyledon cells in seven species of Theobroma (Sterculiaceae)
(Sociedade Botânica de São Paulo, 2008)
The amount of cotyledon polyphenolic cells varies extensively within the Theobroma species. The polyphenolic compounds of these cells play a protective role and furthermore have an important function in the development of ...
Effects of olive oil and its minor constituents on serum lipids, oxidative stress, and energy metabolism in cardiac muscle
(2006-02-01)
Recent lines of evidence suggest that the beneficial effects of olive oil are not only related to its high content of oleic acid, but also to the antioxidant potential of its polyphenols. The aim of this work was determine ...
Cholesterol induces surface localization of polyphenols in model membranes thus enhancing vesicle stability against lysozyme, but reduces protection of distant double bonds from reactive-oxygen species
(Elsevier Science, 2016-07)
The main scope of the present study was to analyze the membrane interaction of members of different classes of polyphenols, i.e. resveratrol, naringenin, epigallocatechin gallate and enterodiol, in model systems of different ...
Antioxidant activity of yerba mate extracts: interactions between the individual polyphenols
(Wiley Vch Verlag, 2013-05)
Yerba mate extracts contain strong antioxidants like chlorogenic (CL) and its derivatives, caffeic (C), quercetin (Q), rutin (R), and kaempferol (K) that may improve food products nutritional quality and rancidity. To ...
Oxidative stress and protective effects of polyphenols: Comparative studies in human and rodent kidney. A review
(2006)
Reactive oxygen species (ROS) play a key role in the pathophysiological processes of a wide range of renal diseases. Thus, antioxidants are expected to decrease the vulnerability of the kidney to oxidative challenges. ...
