目的考察魔芋超细及纳米粉末对营养性肥胖大鼠的减肥作用。方法 用紫外可见分光光度法测定大鼠血液中的甘油三酯、胆固醇和高密度脂蛋白含量 ,用分光光度法测定大鼠血糖值 ,通过测量体重变化及 L ee’s系数考察魔芋超细及纳米粉末的减肥效果。结果 与魔芋精粉及魔芋多糖相比 ,魔芋超细及纳米粉末可明显降低营养性肥胖大鼠的体重和 L ee’s系数 (P<0 .0 5) ,还可明显降低营养性肥胖大鼠血液中的甘油三酯、胆固醇和高密度脂蛋白含量 (P<0 .0 5)。结论 魔芋超细及纳米粉末具有比魔芋精粉及魔芋多糖更明显的减肥作用。

Object To investigate the ultrafine grinding and nanometer powder's antiobesity effect of Amorphophallus rivieri Durieu on nutritional obese rats. Methods The content of triglyceride, cholesterol and high density lipoprotein (HDL) of blood was measured by UV spectraphotometry method. The blood glucose was determined by spectraphotometry method. The antiobesity effect was determined by weight loss and Lee's coefficient. Results Compared with powder and polysaccharide of A. rivieri, the ultrafine grinding and nanometer powder of A. rivieri could significantly decrease the rat body weight and the Lee's coefficient of nutritional obese rats (P0 05), and significantly decrease the content of triglyceride, glucose, cholesterol and HDL in blood of nutritional obese rat (P0.05). Conclusion The antiobesity effect of the ultrafine grinding and nanometer powder of A. rivieri is significantly higher than powder and polysaccharide of A. rivieri.
