In this study fifty 10 weeks old male albino rats weighing 150-200 g were used to investigate the effects of green tea extract on some physiological and histological parameters in alloxan induced diabetic rats. The animals were grouped as N.C, D.C, D.C+Insulin, D.C+GTE50 and D.C+GTE100 respectively. After treatments for four weeks, the results showed that the average body weight and the percentage of body weight gain of diabetic rats were significantly (P 0.05) reduced as compared with the rats of control group. WBC count, the levels of serum glucose, ALP, ALT, AST, creatinine, urea, uric acid, lipid profile cholesterol and triglycerides were significantly (P 0.05) increased in diabetic rats. Histological studies in pancreas, kidney, and liver showed structural changes. Administration of insulin and green tea extracts (GTE50, GTE100) for 28 days significantly (P 0.05) decreased the loss of body weight in diabetic treated rats. Significant decreases in the levels of physiological and hematological parameters were observed. Rats treated with GTE100 was found to almost restore the normal histological architecture of the pancreas, kidney, and liver of diabetic rats."

The inhibitive action of commercial green tea extracts on mild steel (MS) in a 1.0 M hydrochloric acid solution was investigated by weight loss, potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS). A high-performance liquid chromatographic (HPLC) analysis showed conclusively that of the eight catechin monomers and caffeine found in the original extracts, only four components were responsible for the inhibition of MS. The decreasing adsorption capacity of monomers on MS is related to the stereochemistry of molecules and the number of phenolic groups, and it is as follows: epigallocatechin gallate

In this study, we elucidate the anti-obesity effects of EGCG (Epigallocatechin-3-gallate), orange peel extracts (OPE), black tea extracts (BTE), and caffeine (CF) by oral feeding to female CD-1 mice. Female CD-1 mice were fed on high-fat diets containing 0.1% EGCG, 0.2% orange peel extract, 0.2% black tea extract and 0.05% caffeine, singly and in combination for 10 weeks. The body weight gain and weights of abdominal fat and brown adipose tissue were significantly reduced by the diets containing orange peel extract, black tea extract, caffeine, OPE + BTE and OPE + CF. Noticeably, our result also found that mice fed with high-fat diet supplemented daily among the combination of 0.2% OPE + 0.2% BTE + 0.05% CF prevented the body weight gain by 48.8%, the parametrial fat pad weight by 88.2%, retroperitoneal fat pad weight by 82.8% and brown adipose tissue by 63.7% compared to mice fed on high-fat diet. On the basis of these finding, it was supported that oral feeding of orange peel extracts, black tea extracts and caffeine had anti-obesity effects by suppressing body weigh growth and adipose tissue formation. Moreover, it was shown that orange peel extract, black tea extract and caffeine were synergistic in anti-obesity actions. To clarify the anti-obesity action of orange peel extract, female CD-1 mice were fed on various degrees of orange peel extracts and different composition of orange peel extract for 17 weeks. Our results showed that feeding of different degrees of orange peel extracts to female CD-1 mice fed high-fat diet results in the reduction of body weight, white adipose tissue, brown adipose tissue as well as lipid profile includes total cholesterol, triglyceride, LDL and HDL in blood. Furthermore, long term consumption of dietary orange peel extracts intake considerably decreases diet-induced obesity, hyperglycemia, and hypercholesterolemia in mice without a dose-dependent manner.

Abstract: Soy and green tea contain antioxidants that may be used as health promoting ingredients. Various foods currently available on the market incorporate these ingredients individually but few contain a combination of soy and green tea in one product. Since highly acceptable soy bread has been developed, the objective was to optimize the level of green tea addition to the soy bread. The physico-chemical properties of the bread and total phenolics were used as indicators of optimal quality. A 900 gram loaf of plain soy bread was used as control. 0, 50, 100 and 150 mg of green tea extract per 100 g of soy flour were added. pH, water activity (aw), color (Lab values) and hardness (Instron) were measured in all samples. The total phenolics in soy bread extracts were determined spectrometrically according to the Folin- Ciocalteu colorimetric procedure and expressed as mg of gallic acid equivalents (GAE) per gram dry weight. aw, pH and average bread hardness of the crumbs did not show significant differences across the control and the green tea extract fortified soy bread; with the average aw of 0.94, pH of 5.6 and average bread hardness of 3.8 kgf. A decrease in b (decrease in yellowness) and L (increase in darkness) values of the crumbs was observed upon increased addition of the green tea extract. Total phenolics in all samples ranged from 27.45 " 1.82 mg GAE/g dry weight to 30.38 " 0.84 mg GAE/g, demonstrating high total phenolic content but no significant changes between treatments. Results showed that the green tea fortified soy bread was similar to the regular soy bread in terms of the texture, pH and moisture. The amount of green tea per 100 g of flour was too small for a significant increment in total phenolics. However, green tea extract darkened the bread crumbs and reduced visual appeal. Color intensity is an important factor relative to total phenolics in future development of the product. Apart from the color intensity, the addition of the extract did not aversely affect the physico-chemical quality of the soy bread. Sensory acceptability of the product is planned for future studies.

Fresh tea leaves, immediately after harvest, were processed into commercial steamed and roasted green teas. After being extracted with 80°C distilled water for 4 minutes (a 160-fold dilution, w/w), green tea extracts were filtered and processed at 121°C for 1 minute, and then stored at 50°C for 12 days. Samples of fresh, processed, and stored tea extracts were measured for color, evaluated for sensory quality, and analyzed for chemical compositions.
