Notes:
Electron impact ionized purine bases such as caffeine and its metabolites (theopbylline, theobromine, paraxanthine, 1-methylxanthine, 3-metnybumthine and 7-methyIxanthine) were characterized by tandem mass spectrometry. The direct analysts of human urinary extracts by tandem mass spectrometry allows the unambiguous identification of caffeine and its metabolites present simultaneously in the urine.
