摘　　要：为利用天然产物对肥胖进行预防和干预,以特色香蕉新品种‘美食蕉’(Musa spp.Plantain ABB)为材料,以高脂饮食诱导的肥胖大鼠模型为实验对象,设置3个剂量组[1.25、2.5、5.0 g/(kg·BW·d)]及奥利司他阳性对照组,研究美食蕉对肥胖大鼠体重、肝脏、血生化指标、肝功能指标的影响。结果显示,美食蕉干预6周后,低、中、高3个剂量组的大鼠体重极显著低于肥胖对照组(P<0.01),分别降低13.77%、8.44%、11.82%。美食蕉低剂量组明显抑制肥胖大鼠体内脂肪的积累,脂肪系数较肥胖组下降21.11%。肝脏切片显示美食蕉能够减少肝脏脂肪蓄积和炎症。美食蕉干预显著降低血清总胆固醇和甘油三酯水平,与肥胖组相比,干预效果最好的低剂量组分别下降43.85%、66.67%。在美食蕉的干预下,低剂量组的血糖显著低于肥胖组,下降19.31%。美食蕉干预显著降低肝功能指标中的谷草转氨酶的含量。综上所述,美食蕉具有良好的减轻体重效果,并有利于缓解脂肪肝、修复肝损伤和降低血糖、血脂。In order to prevent and intervene obesity with natural products,a new banana variety‘plantain’(Musa spp.Plantain ABB)was used.The banana flour produced with green unripe fruits of plantain,rich in resistant starch.Hereby,the plantain flour was made from a new selected variety,to evaluate the antiobesity effects on obese rats induced by high-fat diet.Three doses(1.25,2.5,5.0 G/(kg BW)d)and orlistat positive control were designed and grouped separately,and the parameters of body weight,liver and blood biochemical indexes in obese rats,were measured after 6 weeks intervention.The results showed that after 6 weeks intervention,the body weight of the rats in the three dose groups was significantly lower than that in the obese control group(P<0.01),which decreased by 13.77%,8.44%and 11.82%respectively.Low dose of plantain could obviously inhibit the fat accumulation in obese rats,and the fat coefficient decreased by 21.11%compared with obese rats.Liver biopsies observation showed that plantain reduced fat accumulation and inflammation in the liver.The intervention significantly reduced total cholesterol and triglyceride levels,compared with the obesity group,the low dose group with the best effect of intervention decreased by 43.85%and 66.67%respectively.Under the intervention of plantain,the blood sugar in the low dose group was significantly lower than that of the obese group,with a decrease of 19.31%.The intervention of plantain significantly reduced the content of aspartate transaminase which is liver function index.To sum up,plantain had a good effect on antiobesity,and it was benefit for the alleviation of fatty liver,repairing the liver damage and reduction of blood sugar and blood fat.
