白骨壤果实7种溶剂提取液的自由基清除作用
Free radical scavenging activity of seven different extracts from the fruits of Avicennia Marina
摘要
Abstract
The dry fruit of Avicennia Marina was extracted with seven different solvent dipping at normal temperature to get methanol extract, water extract,95 % ethanol extract, acetone extract, n- butanol extract ethyl acetate extract and petroleum extract, then their scavenging activities of 2, 2- Diphenyl- 1 - picrylhydrazyl (DPPH) free radical,hydroxyl free radical ( · OH), superoxide free radical ( O2- · ) were measured by the methods of DPPH, Fenton,pyrograllol auto-oxidation respectively. The results showed higher extraction rate and total flavonoids yield in water extract,methanol extract and 95% ethanol extract, and all seven extracts exhibited certain radical scavenging activities on DPPH · , · OH and O2- · .The antioxidant and radical scavenging activities of water extract,95%ethanol extract and methanol extract was higher than acetone extract, n-butanol extract and ethyl acetate extract,while weak activity in petroleum extract.关键词
