Tea polyphenols especially catechins have long been studied for their antioxidant and radical scavenging properties. Scientists throughout the world have investigated the usefulness of the regular green tea consumption in several disease conditions. In-vitro and in-vivo experiments on catechins especially epigallocatechingallate have revealed a significant role in many ways. Reactive oxygen species have been increasingly implicated in the pathogenesis of many diseases and important biological processes. Toxic effects of these oxidants, commonly referred to as oxidative stress, can cause cellular damage by oxidizing nucleic acids, proteins, and membrane lipids. Oxidative stress has been related to aging and age related disorders. It is found that in a wide variety of pathological processes, including cancer, atherosclerosis, neurological degeneration, Alzheimer's disease, ageing and autoimmune disorders, oxidative stress has its implications. Catechins have been reported to be useful in combating aging and age related disorders like cancer, cardiovascular disorders and neurodegenerative diseases. In this mini review we will discuss such studies done across the globe.

This study was carried out to help restore and spread broaden the consumption of Chungtaejeon, a our traditional tea, Chungtaejeon in Korea, and as well as to gather the basic data on Chutaejeon tea. We have also compared the various ingredients components and physiological activities of Chungtaejeon tea extracts with that of green tea extracts. According to the results, the total phenol contents in of the Chungtaejeon and green tea extracts were 90.56 and 98.70 mg/100 mL, respectively, and their tannin contents levels in Chungtaejeon and green tea extracts were 214.14 mg/100 mL and 259.60 mg/100 mL, respectively, showing a difference in content. The catechin contents of the Chetaejeon and green tea extracts were in the order of EGC($15.80{\sim}16.50\;mg/100mL$), EGCG($10.40{\sim}10.60\;mg/100 mL$), and ECG($9.55{\sim}9.88\;mg/100 mL$), however, with the exception of EC(7.86 mg/100 mL) in the green tea extracts, there were not significant differences between that in them Chetaejeon and green tea extracts. Quercetin was the main flavonoid ingredient component in those both the Chungtaejeon and green tea extracts was quercetin, at levels of 0.08 mg/100 mL and 0.06 mg/100 mL and its contents in Chungtaejeon and green tea extracts were 0.08 mg/100 mL and 0.06 mg/100 mL, respectively. The primary amino acid in both tea extracts was theanine main amino acid at levels of, theanine contents were most increased in 8.02 mg/100mL and 10.80 mg/100 mL, respectively, Chungtaejeon tea extracts by 8.02 mg/100 mL and green tea extracts by 10.80 mg/100 mL. And the arginine contents of the Chungtaejeon and green tea extracts in Chungtaejeon and green tea extracts were 1.78 mg/100 mL and 1.86 mg/100 mL, respectively. In terms of mineral composition, potassium content was highest contents in the Chungtaejeon and green tea extracts by 19.80 and 18.04 mg/100 mL, respectively. Finally, the Chungtaejeon tea extracts offered the greatest anti-oxidation and ACE inhibition activities were most increased in the Chungtaejeon tea extracts, and the green tea extracts showed the highest level of nitrite radical scavenging activity at 90% was extremely much increased in the green tea extracts by 90%.

Background: Green tea extracts are approved as nonprescription drug and available as health functional foods, health foods, and beverages. Clinical information on the products is lacking. Methods: Information about the products on green tea nonprescription drugs was obtained from the website of the Korea Pharmaceutical Information Center. The Naver, i.e., a top ranking online search portal, was used for compiling the list of the health functional food products using key words of 'green tea catechin' on August 23, 2018. The recommended daily dosages of catechins were calculated as 30% of the total dried mass of green tea and about 50% of the catechins were considered as epigallocatechin gallate (EGCG). Results: A total of two types of nonprescription drugs containing green tea powder or extracts, nine health functional food products, and three types of health foods were found. The regulatory requirements of the EGCG exceeding 800 mg were reported to be associated with adverse effects of elevated liver enzyme. If consumers take several green tea products concurrently, such as nonprescription drugs with health functional foods or health foods, it could exceed the recommended amount of EGCG. Conclusion: The concurrent use of green tea products as nonprescription drugs, health functional foods, and healthy foods may lead to an increased exposure to EGCG. Pharmacists should be aware the availability of various types of green tea products and the potential risk of liver toxicity due to excessive consumption of EGCG.

Polyphenols may be primarily responsible for the health benefits associated with tea consumption. However, the benefits of the tea polyphenols to bone health have not been studied well. The purpose of this study was to investigate the effects of Oolong tea on bone mineral density and bone-related markers in ovariectomized rats. Sprague-Dawley female rats were randomly assigned to Sham-Control, Sham-Oolongtea, Ovx-Control, and Ovx-Oolongtea groups. Bone mineral density (BMD) and bone mineral content (BMC) were estimated by using PIXImus (GE Lunar Co, Wisconsin.) in the spine and femur. After 6 weeks of the experimental diets, body weight gain, food intake, and food efficiency ratio (FER) were significantly higher in Ovx groups than in Sham groups regardless of diet. The serum concentration of calcium, phosphorus, ALP, and calcitonin were not significantly different according to Oolong tea supplementation. There were no significant differences in urinary calcium and phosphorus excretion between all groups. The urinary DPD crosslinks value was significantly higher in the Ovx-Control group than in the Sham-Oolongtea group. Spine BMD, femur BMD, and spine BMD per body weight were significantly lower in the Ovx groups than in the Sham groups regardless of diet. In the OVX group, spine BMC per body weight, femur BMD per body weight and femur BMC per body weight were significantly higher in the Oolong tea groups than in Control groups. It was concluded that Oolong tea supplementation positively influenced bone health in ovariectomized rats.
