维药小枝玫瑰提取物对四氧嘧啶糖尿病小鼠血糖及糖耐量的影响

目的观察小枝玫瑰Branchlets Rosa rugosa Thunb.提取物对四氧嘧啶糖尿病小鼠血糖及糖耐量的影响。方法采用四氧嘧啶造模法建立糖尿病小鼠模型,将造模成功的小鼠分为8组,分别为模型组,小枝玫瑰水提物高、中、低剂量（3.70、1.85、0.93 g/kg）组,小枝玫瑰醇提物高、中、低剂量（2.75、1.37、0.70 g/kg）组和盐酸二甲双胍（阳性药,200 mg/kg）组,另取正常小鼠为对照组,造模成功3 d后开始给药,每天ig给药1次,共30 d。造模后0、10、20、28 d血糖试纸法测定空腹血糖；造模后30 d,进行葡萄糖耐量试验。结果各组小枝玫瑰提取物均能降低糖尿病小鼠血糖、改善其糖耐量,且呈一定量效关系,其中以醇提物高剂量效果最好,但不及阳性药盐酸二甲双胍。结论小枝玫瑰提取物可以降低糖尿病小鼠血糖,对糖尿病小鼠糖耐量有改善作用。

Effects of Uygur Medicine Branchlets roses extracts on blood glucose and glucose tolerance in diabetes mice induced by alloxan

Objective To observe the effect of extract from Branchlets roses on blood glucose and glucose tolerance in diabetes mice induced by alloxan.Methods Diabetes animal model was established by alloxan.Dividing the model mice into eight groups:model group,water extract high,middle,and low dose (3.70,1.85,and 0.93 g/kg) group,and ethanol extract high,middle,and low dose (2.75,1.37,and 0.70 g/kg) group,and metformin (positive drug,200 mg/kg) group,and normal mice were taken as control group.Drug was ig administered to mice 3 d after molding once daily.Blood glucose test paper was used to determine fasting blood glucose 0,10,20,and 28 d after modeling,and the glucose tolerance test was performed 30 d after modeling.Results The extract of Branchlets roses from all the groups could decrease the blood glucose and improve the glucose tolerance,and showed a certain dose-effect relationship.In all the extracts,the alcohol extract had the best effect,but the effect was not as good as the positive control drug metformin hydrochloride group.Conclusion The extract of Branchlets roses can reduce the blood sugar content of diabetic mice,and improve the glucose tolerance.
