COMPARATIVE STUDY OF RADICAL SCAVENGING ACTIVITY AND PHYTOCHEMICAL ANALYSIS OF FRESH AND DRY RHIZOMES OF CURCUMA ZEDOARIAAbstract
Oxygen is an element obligatory for life. Biological combustion produces harmful intermediates called free radicals. Free radicals are continuously produced by the body’s aerobic life and our metabolism. Antioxidants are the substances, which act against oxidative compounds. Under normal conditions the body’s antioxidants convert ROS to prevent the over production of free radicals. Recently, natural foods and food derived antioxidants such as vitamins and phenolic phytochemicals, have received growing attention, because they are known to function as chemo preventive agents against oxidative damage and are considered beneficial for human health. The present study was conducted to compare the antioxidant activity of fresh and dry rhizomes of Curcuma zedoaria. The methanol extract of both the rhizomes showed good radical scavenging activity.
