Antioxidant and antiacetylcholinesterase activities of chard (Beta vulgaris L. var. cicla)

Plants have been used for many years as a source of traditional medicine to treat various diseases and conditions. Many of these medicinal plants are also excellent sources for phytochemicals, many of which contain potent antioxidant and antiacetylcholinesterase activities. Chard (Beta vulgaris L var. cicla) is widely spread in Turkey and used as an antidiabetic in traditional medicine. In the present study, the antioxidant activity and acetylcholinesterase inhibitor capacity of chard were examined. In addition, proline level of chard was determined. The antioxidant activity of water extract of chard was evaluated using different antioxidant tests. The results were compared with natural and synthetic antioxidants. The results suggest that chard may provide a natural source of antioxidant and antiacetylcholinesterase activities and proline content. (C) 2010 Elsevier Ltd. All rights reserved.
