湖北青砖茶减肥作用研究

The Anti-obesity Effects of Hubei Qingzhuan Tea on Rats

本文探讨了当年湖北青砖和10年青砖茶对肥胖大鼠的减肥作用。结果表明:与肥胖模型组比较,当年青砖茶和10年青砖茶都能极显著降低肥胖大鼠体重、Lee’s指数和脂肪系数,能极显著降低大鼠血清和肝脏中TC、TG、MDA的含量,提高HDL-C、SOD和GSH-PX的含量。脂肪细胞观察表明,喂饲当年青砖茶和10年青砖茶大鼠的脂肪细胞中脂滴含量明显减少,脂肪细胞直径明显变小。说明湖北青砖茶具有明显的减肥抗氧化作用,当年青砖茶的减肥效果具有剂量依赖关系,10年青砖茶减肥效果优于当年青砖茶。

The anti-obesity effects of Hubei Qingzhuan tea on rats were investigated. The results showed, compared with the obese control group, New Qingzhuan tea of this year（NQT） and the Qingzhuan tea which had been stored for 10 years（QTS） reduced the body weights of rats, Lee＇s index and the ratio of body fat and mass significantly. Both teas possessed obvious effects on lowering the serum and liver level of TC, TG, MDA, increasing HDL-C levels and the activities of SOD, GSH-PX. The observation on the fat tissue showed that both teas could reduce the accumulation and volume of fat cells. As a results, New Qingzhuan tea had the effects of anti-obesity and antioxidation. The effects of anti-obesity increased with the dose adding of NQT, and the anti-obesity effects of QTS were better than that of the NQT.
