Antioxidation activity and total phenolic contents of various Toona sinensis extracts

摘要

The purpose of this study was to analyze the antioxidation activities and total phenolic contents of?Toona sinensis. An extractive method of the antioxidant activities of localT. sinensis?leaf extracts and various antioxidation models were analyzed. The effects of various solvent concentrations to extract the?T. sinensis?leaf on the antioxidation activity were compared. The results showed that the?T. sinensis?leaf extracts of various solvent concentrations had good antioxidant activities. The chelating abilities of ferrous ion in the?T. sinensis?leaf extracts obtained from various solvent concentrations were above 80%. It is concluded that?T. sinensis?leaf extracts could be used as biopreservatives of food products. The total antioxidant activities, chelating abilities of ferrous ions and reducing capacities of the?T. sinensis?leaf extracts might provide a substitute for a natural antioxidant.
