Antioxidant properties of grape polyphenol concentrate from Kazakhstan region

It is believed that the antioxidant effects are widespread among plant polyphenols. Antioxidant effect is associated with main biological activities of polyphenols. Objective. To describe the antioxidant effect of grape polyphenol concentrate from Kazakhstan selection in vivo on models of pathologies with overproduction of free radicals

The Protective Properties of the Extract of Polyphenols from Grapes of Cabernet Sauvignon Varieties In The Model of Acute Radiation Sickness in Rats

To investigate possible protective effect of the polyphenol concentrate from Cabernet Sauvignon collection of grapes in rat model of acute radiation sickness (ARS)

Comparison of Phenolic Content in Cabernet Sauvignon and Saperavi Wines

Several studies reveal that the phenolic compounds present in the wine and their concentrations determine physiological activities of the red wine. In this study, the main polyphenol components, including hydroxycinnamic acids, flavones, flavan-3-ols and stilbenoids, were investigated via HLPC-UV in the “Cabernet Sauvignon” and “Saperavi” wines selected from different regions and different years. In assistance of a meta-analysis, we found that there are no fundamental differences in phenolic compounds between the wines Cabernet Sauvignon and Saperavi. However, the amounts of several important phenolic materials such as catechin, caffeic acid, p-coumaric acid, chlorogenic acid and myricetin significantly higher in Saperavi wine as compared to Cabernet Sauvignon. Moreover, on the basis of the correlation analysis, we assume that flavones synthesis and regulation of stilbenoids coordinated to a greater extent in “Saperavi” than in “Cabernet Sauvignon”
