芒果废弃物不同部位乙醇提取物DPPH·自由基清除能力的研究
Comparative Study on DPPH Free Radical Scavenging Activity of Ethanol Extracts from Different Parts of Mango Waste
摘要
Abstract
[ Objective ] The aim was for comprehensive development and utilization of mango waste. [ Method ] 1,1-Diphenyl-2-pierylhydrazyl ( DPPH· ) was used to test the antioxidative activity of mango ethanol extracts. And the antioxidative activity was compared among different extracts. The content of flavonoid of the ethanol extracts was determined with rutin being reference substance and AICI3 as color development reagent. [ Result] The ethanol extracts of mango waste had obvious scavenging activity on DPPH., and scavenging capability increased with the concentration of ethanol extract increasing. The capability of scavenging free radical DPPH · of different parts of mango waste could be summarized as follows: peel ＞ nucleolus ＞ clothing of nucleolus ＞ crust of core. The flavonoid content of ethanol crude extract of different parts was degressive from clothing of nucleolus, crust of core, peel to nucleolus. [ Conclusion] The capabilily of scavenging free radical DPPH'of mango waste was partly caused by flavonoids. Mango waste, including peel, nucleolus, clothing of nucleo1us and crust of core, had the promising value to be explored as the natural antioxidative agent.关键词
