Theobromine is an odorless white crystalline powder. Bitter taste. pH (saturated solution in water): 5.5-7. (NTP, 1992)|Theobromine is a dimethylxanthine having the two methyl groups located at positions 3 and 7. A purine alkaloid derived from the cacao plant, it is found in chocolate, as well as in a number of other foods, and is a vasodilator, diuretic and heart stimulator. It has a role as an adenosine receptor antagonist, a food component, a plant metabolite, a human blood serum metabolite, a mouse metabolite, a vasodilator agent and a bronchodilator agent.|Theobromine (3,7-dimethylxanthine) is the principle alkaloid in Theobroma cacao (the cacao bean) and other plants. A xanthine alkaloid that is used as a bronchodilator and as a vasodilator. It has a weaker diuretic activity than theophylline and is also a less powerful stimulant of smooth muscle. It has practically no stimulant effect on the central nervous system. It was formerly used as a diuretic and in the treatment of angina pectoris and hypertension.
