Objective: To study the scavenging action of alcoholic extracts from Riadix Asparag on oxygen free radical.Method: The Asparagus ethanol-extraction liquid was estracted by ethanol refluxing extraction.Auto-oxidation in alkalcsent solution with pyrogallol can generate O2-and the system of 1
10-phenathroline-Fe(Ⅱ)/H2O2 canproduce·OH.Spectropholomemy was used to observe the effect of alcoholic extracts from Riadix Asparag upon O2-and·OH.Result:The alcoholic extracts from Riadix Asparag could decrease the levels of O2-and inhibit the generation of O2-in vitro;alcoholic extracts from Riadix Asparag could reduce the leve of ·OH(P<0.05).Inhibition ratio is 35.1%±0.16%.Conclusion:Guizhou alcoholic extracts from Riadix Asparag could scavenge and inhibit O2-markedly and scavenge·OH as well.
