三种天然提取物的减肥降脂作用研究

选用Wistar雄性大鼠,喂饲高脂饲料,建立预防性肥胖高血脂模型,对苦丁茶水提取物、阿拉伯糖、乌龙茶提取物三种天然成分进行减肥降脂试验。大鼠随机分组,灌胃给药,以药物曲美减肥胶囊为阳性对照组。测定模型组、给药实验组、阳性对照组各种生化指标(如总胆固醇、甘油三酯、低密度脂蛋白和高密度脂蛋白)、大鼠的体重、Lee′s指数和脂肪湿重等。结果表明:各给药实验组较模型对照组体重增长减慢,且下降明显,体内脂肪湿重也明显下降,同时发现L-阿拉伯糖组有极其显著降低血清总胆固醇、甘油三酯、低密度脂蛋白胆固醇、Lee′s指数和体内脂肪含量(P0.01)的效果。L-阿拉伯糖对肥胖症、高血脂症具有良好的预防和治疗的作用。

Effect of three natural ingredients on body weight-reducing and serum lipid-reducing

70 male wistar rats were randomly divided into 7 groups according to body weight,and fed with a high fat diet and supplement to set up the model rat of obesity and hyperlipemia. Qumei medicine was used as a positive control,extract of Ku-Ding-Cha,L-arabinose and extract of oolong tea used as experimental controls to investigate their effect on body weight-reducing and secrum lipid-reducing. After continuing administration,the biochemical markers of different groups,including model control,positive control a...
