Chemical investigation indicates that caffeine and theine are the same and theobromine is a closely related substance.
Caffeine and theobromine have also quite different relations.
It is slightly stimulating as well, because of the theobromine present and because it is served hot.
Caffeine, it will be remembered, is the methyl ester of theobromine, and can be prepared from it.
Its active principle is theobromine, an alkaloid greatly resembling caffeine, the active principle of coffee and tea.
The artificial preparation of theobromine and caffeine from xanthine, and guanine also show clearly their relations.
theobromine, the essential element of cocoa and chocolate, is identical with the thein and caffeine of tea and coffee.
The mild stimulating property which cocoa possesses is due to the presence of the two substances, theobromine and caffein.
The presence of theobromine is peculiar to cocoa, but caffein is a stimulating principle which also occurs in tea and coffee.
The physiological effects of theobromine are like caffeine but are obtained by smaller doses.
theobromine the·o·bro·mine (thē'ō-brō'mēn')
A bitter, colorless alkaloid found in chocolate products and used as a diuretic, vasodilator, and myocardial stimulant.
A bitter, colorless alkaloid that occurs in the cacao bean, cola nuts, and tea. It is found in chocolate products and used in medicine as a diuretic, vasodilator, and myocardial stimulant. Theobromine is a xanthine and similar in structure to caffeine and theophylline. Chemical formula: C7H8N4O2.
