Objective: To explore the effects of Kunlun snow chrysanthemum on decreasing blood glucose of type two diabetes mellitus (T2DM) mice. Methods: Fifty T2DM mice were divided into pioglitazone group, positive control group, high, moderate and low doses groups of Kunlun snow chrysanthemum according to random number table, ten mice each group, ten mice in the normal control group were established. Normal control group and positive control group accepted intragastric administration of 0.9% sodium chloride solution by standard of 0.001 mL/kg each day; high, moderate and low doses groups of Kunlun snow chrysanthemum lavaged aqueous solution of Kunlun snow chrysanthemum in the concentrations of 0.4, 0.2 and 0.1 g/kg by standard of 0.01 mL/g; pioglitazone group aqueous solution of pioglitazone by standard of 0.01g/kg, once per day, for 35 consecutive days. General condition, preprandial blood glucose, 2hours postprandial blood glucose, serum insulin and insulin sensitivity index(ISI) were observed. Results: Kunlun snow chrysanthemum could significantly decrease body weight and fasting blood glucose of the mice, and its effects were superior to these of pioglitazone; while equivalent to pioglitazone in decreasing 2hours postprandial blood glucose and improving ISI. Conclusion: Kunlun snow chrysanthemum could decrease blood glucose and the levels of insulin of T2DM mice, and improve insulin resistance of the mice.%目的:探讨昆仑雪菊水提物对2型糖尿病小鼠的降糖作用.方法:将2型糖尿病小鼠50只,按随机数字表法分为吡格列酮组、阳性对照组,昆仑雪菊高、中、低剂量组,每组10只,另设正常对照组10只.正常对照组和阳性对照组每日以0.001 mL/kg灌服0.9%氯化钠溶液;昆仑雪菊高、中、低剂量组每日分别以0.4、0.2、0.1 g/kg浓度按0.01 mL/g体质量灌服昆仑雪菊水溶液;吡格列酮组按每日0.01 g/kg灌服吡格列酮水溶液,1次/d,连续35天.观察小鼠一般情况及餐前、餐后2小时血糖,血清胰岛素及胰岛素敏感指数.结果:昆仑雪菊可显著降低病鼠体质量及空腹血糖值,效果优于吡格列酮;而在降低2小时血糖和提高胰岛素敏感性方面与吡格列酮药效相当.结论:昆仑雪菊具有降低2型糖尿病小鼠血糖、胰岛素水平及改善小鼠胰岛素抵抗的作用.
