Abstract: Objective:To study hypoglycemic effect and antioxidation of sweet potato glycoprotein(SPG) on alloxan-iduced diabetic mice.Methods:SPG was obtained from the cultivar Guangdong 98 via water extraction,alcohol precipitation and gel filtration.The effects of SPG on blood glucose contents were discussed activities of SOD and CAT and the contents of MDA in liver,brain and serum of the can diabetic mice were discussed.Results:SPG lowers the blood glucose contents of diabetic mice(p<0.01),increases the activities of SOD and CAT(p<0.05 or p<0.01) and decreases the contents of MDA(p<0.01) in liver,brain and serum.Conclusion:SPG can significantly lower the blood glucose and has in vivo antioxidation function to alloxan diabetic mice.
