Assessment of the chemical profile, polyphenol content and antioxidant activity in extracts of Psidium Guajava L. fruits
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 ...
Modulation of endogenous antioxidant system by wine polyphenols in human disease
Numerous studies indicate that moderate red wine consumption is associated with a protective effect against all-cause mortality. Since oxidative stress constitutes a unifying mechanism of injury of many types of ...
Potential Role of Polyphenols in the Prevention of Cardiovascular Diseases: Molecular Bases
(Bentham Science, 2016)
Cardiovascular diseases (CVD) are the leading cause of mortality worldwide. It is widely accepted that oxidative stress plays a key role in their development and progression; hence oxidative damage might be abrogated by ...
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
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
(Sociedad de Biología de Chile, 2000)
Polyphenols and mitochondria: An update on their increasingly emerging ROS-scavenging independent actions
Polyphenols, ubiquitously present in fruits and vegetables, have been traditionally viewed as antioxidant molecules. Such contention emerged, mainly from their well established in vitro ability to scavenge free radicals ...
Layer-by-Layer Thin Film of Iron Phthalocyanine as a Simple and Fast Sensor for Polyphenol Determination in Tea Samples
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 ...
