A large amount of external factors that can foster the emergence of free radicals in organisms has created a imminent need for understanding and technologies that enables the search of antioxidant componds and extraction of antioxidants from natural sources. These compounds have great potential for kidnapping free radicals which are highly harmful to organisms, being the principal responsible for the decrease in the shelf life of foods, and aging. These free radicals are also related to diseases such as AIDS, arthritis, diabetes, heart disease and others. Fruits and vegetables are true mines of compounds with antioxidant potential, its vitamins and phenolic compounds present an essential role in the nutrition of living beings acting as a defense against degradation of lipids and proteins, which indicates the importance of a diet rich in these nutrients, given that part of the antioxidant defenses of the body comes from the diet.
