    AbstractIn view of the high concentration of resveratrol found in a new autochthonous wine (Uvalino) and the notable antioxidant activity of this substance, we decided to assess whether this wine could inhibit the production of free radicals. Nowadays, free radicals are considered to be the most noxious factors for tissues, triggering the development of many diseases. The assessments were carried out using a direct and more precise technique, electronic paramagnetic resonance (EPR), which is able to detect the ability of an antioxidant agent to inhibit the formation of hydroxyl radicals (*OH), which are among the most noxious reactive oxygen species (ROS). The results show that Uvalino wine is able to eliminate ROS production almost completely. Consequently, it has beneficial effects on health in all the diseases in which ROS plays an important pathogenetic role.
