| Antioxidants are widely used as ingredients in dietary supplements in the hope of maintaining health and preventing diseases. Antioxidants also prevent food spoilage via food additive. But use of synthetic antioxidants is not safe due to their health risks and toxicity . The search for antioxidants from natural sources has received much attention to identify compounds that act as suitable antioxidants and replace the synthetic ones. In addition, these naturally-occurring antioxidants can be formulated to give neutraceuticals that can help to prevent oxidative damage from occurring in the body . There are several types of antioxidants which include vitamins,A.E.C, and B-complex the mineral selenium, Zinc and the synthetic compound BHT and BHA. Epidemiological evidence suggest that consumption of fruits and vegetables my reduce the risk of both cancer and cardiovascular disease and it has been hypothesized that this is due in part to the presence of antioxidants compounds in fruit and vegetables. Species like Coleus amboinicus, Spilanthus paniculata are perennial herbs commonly used in regular vegetable combination traditionally. This research exercise is an attempt to estimate types and quantity of kinds of antioxidants available in these species. |
