Antioxidants play important role in the prevention of free radical formation and helps in reducing various disorders such as cancer, aging, cardiovascular disease, cataracts, immune system decline, and brain dysfunction. There are several foods such as fruits, green leafy vegetables, tea, coffee, nuts and oilseeds which have been found to have good antioxidants potential. Antioxidants are abundant in natural dietary sources, and the consumption of antioxidants has a lot of potential health benefits. Antioxidants are essential and important for plants and animals’ sustenance. They are substances that protect cells from the damage caused by unstable molecules known as free radicals. The types of antioxidants such as ascorbic acid, glutathione, melatonin, tocopherols and tocotrienols were reported. The classification and characteristics of antioxidant; its measurements and level in food and free radicals were also documented. Antioxidants are an inhibitor of the process of oxidation, even at relatively small concentration and thus have diverse physiological role in the body. Antioxidant constituents of the plant materials like fruits act as radical scavengers and helps in converting the radicals to less reactive species. A variety of free radical scavenging antioxidants is found in dietary sources such as fruits, vegetables and tea, etc. This review presents some information about the antioxidant/antiradicals and their role in our body and also their presence in a few fruits selected for the study
