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).
