[Effect of a complex tea on reducing blood lipid in rabbits]

In order to observe the effect of a complex tea composed of tea, ginkgo leaf, red koji and fructus lycii on reducing blood lipids in experimental rabbits, 40 rabbits weighted from 1.5 to 2.0 kg were divided randomly into 5 group: (I) normal control group, (II) hyperlipidemia model(positive control), (III) green tea control group, (IV) low dose complex tea group, and (V) high dose complex tea group. Blood triglyceride(TG), cholesterol(TC), lower density lipoprotein(LDL) and high density lipoprotein(HDL) were measured before experiment and 6.12 weeks later. Then the pathological changes of heart, aorta and liver were observed. After 12 weeks of experiment, the results showed that, (1) hyperlipidemia characterized by high TC has been induced by high-fat feeds in group II, (2) the complex tea can reduce body weight and eliminate the lipids deposition in aorta and liver. (3) the complex tea can decrease serum TG, TC,LDL and increase serum HDL in the high complex tea group. The results indicate that the complex tea is more effective than green tea on reducing blood lipids in experimental rabbits.
