目的从肠道微生态角度研究绿茶摄入量对小鼠肠道微生物和酶活性的影响,探析饮茶(绿茶)有益健康的机制,为饮茶做出科学指导。方法将SPF级实验小鼠随机分为正常对照组、低浓度绿茶摄入组、中浓度绿茶摄入组和高浓度绿茶摄入组。低、中、高浓度绿茶摄入组分别给予10%、20%和30%(g/g)的茶水溶液,连续灌胃1个月后采集空肠至回肠段内容物进行微生物和酶活性分析,同时观察实验动物体质量变化情况。结果各实验组小鼠体质量增长与对照组相比无明显差异;与对照组相比,低浓度绿茶摄入组小鼠肠道乳酸菌数降低而细菌数升高,中浓度摄入组乳酸菌数、细菌以及双歧杆菌数显著降低,高浓度摄入组细菌数、双歧杆菌数...

Objective To investigate the mechanism of green tea for health from the point of intestinal microbes and enzyme activities. Methods SPF mice were randomly divided into the control group, low dose group, medium dose group and high dose group.Mice of low dose group, medium dose group and high dose group were treated by gavage with green tea solution in concentrations of 10%, 20% and 30% (g/g) respectively for 1 month, then the contents in jejunum to ileum were collected to analyze the intestinal microbes and enzyme activities.Changes of the mice weight were observed too. Results Compared with th...
