Anti-stress effects of drinking green tea with lowered caffeine and enriched theanine, epigallocatechin and arginine on psychosocial stress induced adrenal hypertrophy in mice
Conclusion These results suggest that drinking green tea exhibits anti-stress effects, where theanine, EGC and Arg cooperatively abolish the counter-effect of caffeine and EGCG on psychosocial stress induced adrenal hypertrophy in mice. Graphical abstract (Source: Phytomedicine)

Molecules, Vol. 21, Pages 940: Green Tea Leaves Extract: Microencapsulation, Physicochemical and Storage Stability Study
This study showed that total catechin, total phenolic content (TPC) and antioxidant activity did n ot decrease significantly (p ≥ 0.05) under 4 °C storage conditions. The half-life study results were in the range of 35–60, 34–65 and 231–288 weeks at storage temperatures of 40 °C, 25 °C and 4 °C respectively, therefore, for improved shelf-life stability we recommend that microparticles should be stored at temperatures below 25 °C.

Therapeutic potential of green tea on risk factors for type 2 diabetes in obese adults – a review
The objective of this review was to investigate the effects of green tea on body composition, oxidative stress, inflammation and insulin resistance, risk factors for the development of type 2 diabetes in obese individuals and the mechanisms that underlie the modulatory actions of green tea compounds on these risk factors. Although green tea has therapeutic potential in the treatment of obese individuals, the findings of this review demonstrate the need for a greater number of studies to confirm the positive effects of green tea, especially regarding the modulation of obesity.

α-TEA inhibits the growth and motility of human colon cancer cells via targeting RhoA/ROCK signaling.
In conclusion, these results indicate that α-TEA inhibits growth and motility in colon cancer cells possibly by targeting RhoA/ROCK signaling. Moreover, combined with RhoA or ROCK inhibitors, α-TEA may exhibit a more effective inhibitory role in colon cancer.

A tandem mass spectrometry method based on selected ions detects low-abundance phenolics in black tea - theatridimensins as products of the oxidative cascade.
CONCLUSIONS: When exploring black tea for the occurrence of two-step-oxidation products, the use of MS/MS on selected ions combined with extracted ion chromatography proved to be the most suitable. The occurrence of T3Ds and T3Dgs in various black teas was shown for the first time and the 'oxidative cascade hypothesis' was extended with novel oxidation products.

A method for producing superfine black tea powder with enhanced infusion and dispersion property
Publication date: 1 January 2017 Source:Food Chemistry, Volume 214 Author(s): Weihua Xiao, Yang Zhang, Chongxin Fan, Lujia Han Tea is rich in healthy components including polyphenols, caffeine, gallic acids, and others. Current technology of tea infusion and extraction leads to more than 40% soluble solids wasted in spent leaf. To increase the bioaccessibility of black tea, we report a method of pulverization treatments including general and superfine grinding to reduce the particle size. In comparison with coarsely ground black tea powders (BTPs), the superfine ground BTP with medium diameter 6.9μm resulted i...

Inhibition of green tea and the catechins against 1-deoxy-d-xylulose 5-phosphate reductoisomerase, the key enzyme of the MEP terpenoid biosynthetic pathway.
This study would be very helpful to elucidate the antimicrobial mechanism of green tea and the catechins and also would be very useful to direct the rational utilization of them as food additives.

The antioxidant effect of Green Tea Mega EGCG against electromagnetic radiation-induced oxidative stress in the hippocampus and striatum of rats.
This study also extends to evaluate the therapeutic effect of green tea mega EGCG on the previous parameters in animals exposed to EMR after and during EMR exposure. The experimental animals were divided into four groups: EMR-exposed animals, animals treated with green tea mega EGCG after 2 months of EMR exposure, animals treated with green tea mega EGCG during EMR exposure and control animals. EMR exposure resulted in oxidative stress in the hippocampus and striatum as evident from the disturbances in oxidant and antioxidant parameters. Co-administration of green tea mega EGCG at the beginning of EMR exposure for 2 and 3 ...
