Phytochemistry, 1964
Abstract The rates of hydrolysis of more than a hundred flavonoid glycosides have been measured, using N HCl, β-glucosidase, β-glucuronidase or anthocyanase. The results show that such measurements are useful (α) in distinguishing O- from C-glycosides, (b) in characterizing flavonoids having sugars attached to more than one hydroxyl group, and (c ...

Activation of eNOS by Polyphenol-rich Products and Polyphenolic Compounds
Current Pharmaceutical Design, 2014Numerous epidemiological studies indicate that consumption of polyphenol-rich food and beverages is associated with a protective effect on the cardiovascular system. The beneficial effect has been attributable to several mechanisms including the improvement of the vascular function.

Polyphenols and Polyphenol-Derived Compounds and Contact Dermatitis
2014Polyphenols and polyphenol-derived compounds from plants are common causes to skin reactions resulting in allergic contact dermatitis, photodermatitis and/or irritant dermatitis. Allergic contact dermatitis is the most common skin reaction caused by plant products.

Polyphenols Excreted in Urine as Biomarkers of Total Polyphenol Intake
Bioanalysis, 2012Nutritional biomarkers have several advantages in acquiring data for epidemiological and clinical studies over traditional dietary assessment tools, such as food frequency questionnaires. While food frequency questionnaires constitute a subjective methodology, biomarkers can provide a less biased and more accurate measure of specific nutritional intake.

Natural Polyphenols and Cardioprotection
Mini Reviews in Medicinal Chemistry, 2011With more than 8000 polyphenols found in food (mainly, wine, tea, coffee, cocoa, vegetables and cereals), many epidemiological studies suggest that the intake of polyphenol-rich foods has a beneficial effect on a large number of cardiovascular risk factors, such as high blood pressure, high blood cholesterol, obesity, diabetes and smoking.

Antibacterial Activity of Polyphenols
Current Pharmaceutical Biotechnology, 2014Polyphenols are a widely distributed group of natural products found in fruits, vegetables, nuts, seeds, stems and flowers. Such compounds, especially dietary flavonoids and tannins, have been shown to exert antioxidant, antiinflammatory, anti-cancer and antibacterial effects and may have beneficial effects on human health.

Polyphenols in Health and Disease
Cell Biochemistry and Biophysics, 2015Deadly diseases, such as cardiovascular diseases and cancer, remain the major health problems worldwide. Research in cardiovascular diseases and genome-wide association studies were successful in indentifying the gene loci associated with these threatening diseases. Yet, a substantial number of casual factors remain unexplained. Over the last decade, a

Polyphenolic Antioxidants and Health
2012Oxidative stress is believed to play a pivotal role in several physiologic (aerobic metabolism, immunologic responses, cellular signaling, regulation of gene expression, cell differentiation) [1] and pathologic (atherosclerosis, tumorigenesis, neurodegenerative diseases, etc.) processes. Antioxidants react with oxygen free radicals protecting the cells
