摘　　要：目的 :观察橄榄叶提取物对正常及糖尿病小鼠血糖、血脂水平的影响。方法 :给小鼠腹腔内注射链脲佐菌素建立糖尿病小鼠模型 ,观察橄榄叶醇提取物高、中、低剂量组对正常小鼠血糖的影响 ,橄榄叶醇提取物和酯提取物的高、中、低剂量组对糖尿病小鼠血糖、血清总胆固醇、甘油三酯、高密度脂蛋白胆固醇、低密度脂蛋白胆固醇的影响。结果 :橄榄叶醇提取物的高、中剂量组对正常小鼠有明显降血糖作用。橄榄叶醇提取物及酯提取物的高、中、低剂量组均能降低糖尿病模型小鼠的血糖水平 ,且酯提取物的降血糖作用明显强于醇提取物。橄榄叶的酯提取物能对抗糖尿病模型小鼠血清中总胆固醇、甘油三酯和低密度脂蛋白胆固醇的升高。结论 :橄榄叶提取物具有降血糖和调节血脂的作用。Objective To investigate the effects of olive leaf extract on glycemia and lipidemia in normal and diabetic mice induced by steptozocin.Methods The living diabetic mice model was established by intra peritoneal injection of streptozocin.The effect of Et?OH fraction of olive leaf extract on blood glucose of normal mice was explored,so was the effect of Et?OH and Et?Oac fractions on blood glucose,serum total cholesterol,triglyceride and high and low-density-lipoprotein cholesterol of diabetic mice.Results Compared with the normal control group,the Et?OH fraction of high and middle doses could significantly decrease the blood glucose in normal mice.Both Et?OH and Et?Oac fractions could remarkably decrease the blood glucose in diabetic mice.In addition,hypoglycemic function of Et?Oac fraction was more obvious than that of Et?OH fraction.There was no manifest relationship between effects and doses.At the same time,it's also shown that Et?Oac fraction could decrease the level of serum total cholesterol,triglyceride and low density lipoprotein cholesterol in diabetic mice.Conclusion Olive leaf extract can regulate blood glucose and the blood lipids.
