Reactive oxygen species (ROS) have been implicated in degenerative diseases such as cancer, inflammation, atherosclerosis and aging as also in food deterioration [1]. A balance between free radicals and antioxidants is necessary for proper physiological function. Many human diseases are caused or negatively affected by free radicals. The natural defence of the human organism against free radicals is not always sufficient mainly due to the significant exposition to free radicals from external sources in the modern world. The dietary intake of antioxidants plays an important role in the protection of the human organism against free radicals. Many clinical and epidemiological studies show a connection between the antioxidant activity of the substances present in the diet and the prevention from such diseases as cardiovascular diseases or carcinogenesis [1-4]. Fruits, vegetables, grains, teas and some kinds of spices are natural sources of antioxidants. Medicinal plants used in the traditional medicine and healing are one of these sources of antioxidants. In this work antioxidant capacity of Rosa damascene aqueous extract has been determined with simple and sensitive electrochemical methods.
