Study of fermented pu-erh tea powder, dark tea powder and liupu tea on losing weight in hyperlipidemia model rats

Objective: The effects of fermented pu-erh tea powder, dark tea powder and liupu tea on losing weight in hyperlipidemia model rats were investigated. Methods: Wistar rats were randomly divided into normal group, hyperlipidemia model group, low, medium and high dose group of fermented pu-erh tea powder, dark tea powder, liupu tea, which were 0.5, 1.0, 2.0g· kg-1·bw-1, respectively. All rats were sacrificed after 30 days' test feeding. Levels of pancreatic lipase activity and transaminase activity were measured. Pathological changes of the adipocyte were observed. Results: Compared with the hyperlipidemia model group, fermented pu-erh tea powder, dark tea powder and liupu tea groups could effectively restrain the increasing weight of the rats(P0.05) and there was no difference in food intake. All doses of fermented pu-erh tea powder, dark tea powder and liupu tea groups could restrain abdominal fat cells increased(P0.05). Conclusion: Fermented Pu-erh tea powder, dark tea powder and liupu tea have different degrees of protection to nutritional obesity. And that high does group of Liupu tea has the most obvious effect.
