摘　　要：研究香蕉粉、魔芋精粉、抗性糊精、玉米淀粉、左旋肉碱等5种产品对营养性肥胖大鼠的减肥作用。采用营养性肥胖模型法,选取奥利司他作为阳性对照,分别以2.5 g/kg BW·d的剂量饲喂营养性肥胖大鼠,研究不同产品灌胃后营养性肥胖大鼠体重、体脂含量、血糖、血脂水平的变化,观察肝脏病理切片结果,对其减肥功能进行评价。结果表明:香蕉粉和魔芋精粉呈现出控制肥胖大鼠体重增加的效果,香蕉粉组大鼠体内脂肪质量显著低于肥胖对照组(p<0.05);香蕉粉可显著降低肥胖大鼠血糖(GLU)水平(p<0.05),抗性糊精、魔芋精粉、左旋肉碱可显著降低肥胖大鼠总胆固醇(TC)水平(P<0.05)。香蕉粉可在一定程度上改善肥胖大鼠脂肪肝现象。结论:香蕉粉、魔芋精粉、抗性糊精、玉米淀粉、左旋肉碱5种产品在减轻体重或降低体脂、血脂或改善脂肪肝现象方面有一定的效果,且综合多指标结果,香蕉粉的减肥效果较好。The effects of banana powder, konjac powder, resistant dextrin, corn starch and L-carnitine on weight loss in obese rats was studied.

Body weight, body fat content, blood glucose, blood lipid levels of obesity rats were measured and liver pathological section were observated to evaluate the weight losing function of different products. The results showed that banana powder and konjac powder were able to control the trend of weight increase of obese rats. The body fat content of banana powder group was significantly lower than that of the obese control group (P<0.05). Banana powder could significantly reduce blood glucose (GLU) levels in obese rats (P<0.05). Resistant dextrin, konjac powder and L-carnitine could significantly reduce the level of total cholesterol (TC) in obese rats (P<0.05). Banana powder could improve fatty liver symptom in obesity rats. Conclusions were that the banana powder, konjac powder, resistant dextrin, corn starch and L-carnitine had good effects on reducing weight or body fat, blood fat or fatty liver symptom.
