By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Antioxidants. According to news reporting out of Pisa, Italy , by NewsRx editors, research stated, "Antioxidant phytochemicals in fruits and vegetables of a vegetarian diet may account for the reduced risk of aging and stress oxidative associated diseases. In this study, a simple, rapid and accurate new bioassay for the determination of the antioxidant activity of purified or crude plant extracts and thier interactions is described, based on the fluorimetric determination of thiobarbituric acid reactive substances (TBARS) released by UV-B radiated red blood cell (RBC) ghosts."
Our news journalists obtained a quote from the research from the University of Pisa , "Pure resveratrol, white and red wine and pomegranate juice (PJ) were used as antioxidant source to test the biological method. TBARS production is a function of radiation time, the number of RBC ghosts in the radiated sample and the loaded antioxidant. The antioxidant activity of resveratrol was detected at a submicromolar concentration range [0.02 mu g/mL-0.1 mu mol/L]. The activity of red wine was almost 10 times higher than that of white wine, and PJ juice had the highest activity."
According to the news editors, the research concluded: "Submaximal protective effects of PJ and red wine were additive."
