Theine
The alkaloid in tea (trimethylxanthine) that is molecularly identical to caffeine. The quantity of theine (caffeine) depends on the type of tea, age of leaves, position during steaming, oxidation time, leaf size and quantity used in preparing the beverage. In principle, green tea contains less theine (caffeine) than black tea. There are, of course, exceptions which depend on which green or black tea is used, and how the teas were processed. There is no theine in herbal or fruit teas (infusion).
