Assessment of the chemical profile, polyphenol content and antioxidant activity in extracts of Psidium Guajava L. fruits
(2012-12-13)
Fruits and vegetables that are rich in polyphenolic compounds, especially flavonoids, may be used to benefit human health by reducing the incidence of cancers and cardiovascular diseases. Previous studies have demonstrated ...
Cysteine enhances the content of betalains and polyphenols in fresh-cut red beet
(Elsevier B.V., 2019-07-15)
This study investigated the effectiveness of cysteine in conservation of bioactive compounds and the antioxidant capacity of minimally processed red beet. After red beet minimal processing increasing cysteine concentrations ...
The reduction of Cu(II)/neocuproine complexes by some polyphenols: Total polyphenols determination in wine samples
(ELSEVIER SCI LTD, 2011)
A new method is presented for spectrophotometric determination of total polyphenols content in wine. The procedure is a modified CUPRAC method based on the reduction of Cu(II), in hydroethanolic medium (pH 7.0) in the ...
Use of grape polyphenols against carcinogenesis: Putative molecular mechanisms of action using in vitro and in vivo test systems
(2013-03-01)
Polyphenols are present in foods and beverages and are related to sensorial qualities such as color, bitterness, and astringency, which are relevant in wine, tea, grape juice, and other products. These compounds occur ...
Plant Polyphenol Antioxidants and Oxidative Stress

Layer-by-Layer Thin Film of Iron Phthalocyanine as a Simple and Fast Sensor for Polyphenol Determination in Tea Samples
(2016-10-01)
Polyphenols have attracted attention due to their antioxidant capacity and beneficial effects to health. Therefore, fast, inexpensive, and efficient methods to discriminate and to quantify polyphenols are of interest for ...
Anti-atherogenic and anti-angiogenic activities of polyphenols from propolis
(ELSEVIER SCIENCE INCNEW YORK, 2012)
Propolis is a polyphenol-rich resinous substance extensively used to improve health and prevent diseases. The effects of polyphenols from different sources of propolis on atherosclerotic lesions and inflammatory and ...
Green tea polyphenols-whey proteins nanoparticles: Bulk, interfacial and foaming behavior
(Elsevier, 2015-08)
The objective of the work was to study foaming and interfacial properties of β-lactoblobulin and caseinomacropeptide as affected by the formation of nano-particles with increasing amounts of green tea polyphenols. In this ...
