Antioxidant Activities of Total Alkaloids from the Laminae of Elaeagnus mollis Diels

SHAO Fen-juan,YAN Gui-qin,ZHANG Zhi-feng,WANG Jing(School of Life Science,Shanxi Normal University,Linfen,Shanxi 041004,China)  
The total alkaloids were extracted by immersing in alcohol from the laminae of Elaeagnus mollis,and were purified by column chromatography on silica gel.The antioxidant activities of total alkaloids were tested with respect to some parameters,such as the antioxidative stability to axunge,the scavenging of hydroxyl radicals and superoxide anion.The result showed that the antioxidant activity of the total alkaloids to axunge was significantly higher than that of vitamin C;the EC50 of the scavenging of hydroxyl radicals and superoxide anion were 0.236 g/L and 0.101 g/L,when the concentration of total alkaloids was 1 g/L,the scavenging rate of hydroxyl radicals and superoxide anion could reach to 96.04% and 90.05%,which were significantly higher than that of vitamin C.
