The tea plant is a large shrub with evergreen leaves, used medicinally for more than 5000 years in China where it originated. Tea is now the second-most consumed beverage in the world. Based on the different processes in tea making, it is categorized as Green Tea, Black Tea, Oolong Tea, White Tea, Yellow Tea and Dark Tea. A number of beneficial health effects are attributed to regular consumption of green tea and dried/powdered extracts of green tea are available as dietary supplements.
Green tea is prepared by picking, lightly steaming and allowing the leaves to dry. The active constituents in green tea are a family of polyphenols (catechins) and flavonols, which possess potent antioxidant activity. Tannins, large polyphenol molecules, form the bulk of the active compounds in green tea, comprised nearly 90%of catechins. Several catechins are present in significant quantities; epicatechin (EC), epigallocatechin (EGC), epicatechin gallate (ECG) and epigallocatechin gallate (EGCg). EGCg makes up about 10-50% of the total catechin content and appears to be the most powerful of the catechins – with antioxidant activity about 25-100 times more potent than vitamins C and E. A cup of green tea may provide 10-40mg of polyphenols and has antioxidant activity greater than a serving of broccoli, spinach, carrots or strawberries. A number of commercial green tea extracts are standardized to total polyphenol content and/or EGCg content.
