摘要/Abstract

摘要： 以“紫娟”普洱茶茶褐素为对象,研究“紫娟”普洱茶茶褐素对高脂饮食大鼠生长发育的影响。将实验大鼠分为正常对照组,高脂模型组,低、中、高剂量（即动物给药量0.135、0.405、1.215g/kg）茶褐素组及阳性对照组。观察“紫娟”普洱茶茶褐素对大鼠摄食量、饮水量、体质量、体长、肝脏指数的影响;通过电子显微镜观察茶褐素对实验大鼠肝脏病理变化的影响。结果表明：干预期结束后,“紫娟”普洱茶茶褐素对大鼠的进食、饮水、体长无影响;与高脂模型组相比,茶褐素组能抑制高脂饮食大鼠体质量的增长速度,不同程度地抑制了实验大鼠肝脏的脂变,减少肝脏脂肪沉积,具有预防实验动物脂肪肝形成的作用,中、高剂量茶褐素组效果尤为明显（P<0.5）。

Abstract: The effect of theabrownin(TB) extracted from ‘Zijuan’ Pu-erh tea on growth of rats with hyperlipidemia food was studied. The experimental rats were divided into six groups: normal control group, positive control group, hyperlipidemia model group, and low-, medium-, and high-dose theabrownin treatment groups (0.135g/kg, 0.405g/kg, and 1.215g/kg body weight, respectively). The effect of theabrownin extracted from ‘Zijuan’ pu-erh tea on food intake, water intake, body weight and body length, index and pathology section of livers of rats was investigated. After the stage of intervention, TB showed no effect on food intake, water intake, and body length of rats. TB can significantly prevent the increasing of body weight and the fatty degeneration of rat livers with hyperlipidemia food. TB extracted from ‘Zijuan’ Pu-erh tea showed the effect on controlling body weight of hyperlipidemia rats, and it can decrease the fat deposition and prevent the formation of fatty livers of animals, especially with medium and high dose TB(P<0.5).

Key words: ‘Zijuan’, pu-erh tea;, theabrownin, weight, liver index, pathology section
