摘　　要：研究了薯蔓多糖(PSPV)对四氧嘧啶致糖尿病小鼠的降血糖作用。采用昆明种小白鼠分组,分别以PSPV、优降糖或生理盐水灌胃,每天记录饮水量及小鼠体重,实验末期测血糖2次;并研究了PSPV对正常小鼠血糖值的影响。实验结果表明:PSPV能明显缓解糖尿病小鼠消瘦和多饮症状,显著降低其血糖值,并存在量效关系,以高剂量PSPV效果最佳;PSPV对正常小鼠的血糖水平无明显影响。结论:PSPV具有显著的降血糖作用,是一种值得开发利用的植物多糖。To observe the hypoglycemic effect of polysaccharides from sweet potato vines （PSPV） on experimental diabetic mice, mice were divided into different groups. Each group was given PSPV, glybenclamide or normal Saline respectively. Water intake and body weight were recorded dally. The concentrations of serum glucose were measured at the end of experiment twice. The influences of PSPV on the serum glucose of the normal mice were studied too. Results： Symptoms of diabetic mice fed PSPV are alleviated obviously. PSPV can remarkably decrease the serum glucose and water intake of diatetic mice, but increase their body weight. Especially the effect of high dose PSPV is the most remarkable. On the other hand, PSPV has no significant influence on the serum glucose of normal mice. Conclusion： PSPV has significantly hypoglycemic effect on diabetic mice and is worthy to being utilized.
