Abstract

The main target of the present investigation was to study the effect of Tea Types extracts (White, Black, Green and Oolong tea)on hyperglycemic male albino rats.Thirty adult male albino rats, weighting (150-160g) each were divided into six groups, five rats each. One of them was kept as a control –ve group, while the other five groups were diabetic by alloxan injection and fed on basal diet +2cm daily of 5% tea extract for 28 days. Body weight gain, feed intake, feed efficiency ratio, internal organs ,serum glucose, serum liver enzymes activities (ALT, AST, & ALP), kidney function parameters (creatinine, uric acid, & urea levels), serum lipid profiles (TG, TC LDL-c, VLDL-c&HDL-c,) were assessed. From the obtained results it was showed that feeding on Tea types extracts caused significant (P ≤ 0.05) decrease in body weight gain, feed intake, feed efficiency ratio,and increase of HDLc ,but with significant (P ≤ 0.05) decreases in the rest of the analyses parameters as compared with control (+ve) group, and enhanced the kidney and liver functionswith thedecrease of ALT, AST, ALP, serum glucose, creatinine, uric acid, urea which reflects the potent nutraceutical therapeutic effect for feeding on tea types for coping hyperglycemia in rats. All treatments seems to be valuable to cope diabetes 2 (tea 5% extraction).
