Study on Antioxidant of Fructurs Ulmns Pumila Extraction

[Objective]The purpose was to study the scavenging effects of Fructus Ulmns pumila water-extraction and ethanol-extraction on superoxide anion and hydroxyl free radical.[Method]Fructus ulmns pumila extractions were made to analyze the effect of extractions on scavening rate of superoxide anion and hydroxyl radical.[Result]The results showed that whether Fructus Ulmns pumila water-extraction or ethanol-extraction had scavenging effects on superoxide anion and hydroxyl radical.Fructus Ulmns pumila water-extraction had higher scavenging effects on superoxide anion than on hydroxyl radical,but Fructus Ulmns pumila ethanol-extraction had stronger scavenging effects on hydroxyl radical than on superoxide anion.[Conclusion]Fructus ulnms pumila water-extraction and ethanol-extraction have all the better ability of cleanning out hydroxyl radical and controlling superoxide anion.
