THE COMPARATIVE STUDY ON EFFECTS OF QINGZHUAN TEA AND GREEN TEA ON ANTI-OBESITY AND ANT-OXIDATION IN RATS

Objective To analyze the biochemical components of qingzhuan tea and green tea and its effects of anti-obesity and anti-oxidation in rats.Method Two kinds of stored Qingzhuan tea and green tea were analyzed.Sixty Wistar rats with 80±5g weight were randomly divided into six groups (n=10):normal control group and model group ig given with distilled water per day,positive control group treated ig with Orlistat 0.04 g/kg·bw per day,and 3 groups treated ig with 1.5 g/kg·bw per day Qingzhuan tea stored for one year (QT-1),10 years (QT-10) and green tea respectively for 6 w.All treated groups were fed with high fat diet,but the control group with normal diet.Their weight,length,fat pad,blood lipid levels and redox markers were measured.Results In QT-10 group,the contents of polysaccharides and theabrown were the highest,but the other components were lower.The contents of all other components except polysaccharides and theabrown were the greatest in green tea.Compared with the model group,body weight,Lee's index,ratio of body fat and mass,serum lipid and MDA decreased significantly,serum HDL-C,SOD and GSH-Px increased in Orlistat group,Qingzhuan tea group and green tea group significantly.Among them,QT-10 and QT-1 were more effective,and green tea less effective.Conclusion Qingzhuan tea is more effective on anti-obesity than green tea.
