High Performance Liquid Chromatography (HPLC) Method for Analysis of Caffeine , Theophylline , Theobromine
Caffeine is a natural stimulant and methylxanthine alkaloid. with the molecular formula C6H10N4O2 . Caffeine can be found in a variety of plants, including tea, coffea, cocoa, kola nuts, and guarana. Ingestion of it can increase alertness and cognitive function. It can also cause worsening anxiety, heart palpitations, and headaches.
Theophylline is a methylxanthine compound with the molecular formula C7H8N4O2 . It is a caffeine metabolite and is often used in forensic analyses. Besides analytical use, it is often used in treating respiratory conditions.
Theobromine is a methylxanthine alkaloid with the molecular formula C7H8N4O2 . It is a derivative of caffeine. It can be found in many foods, including chocolate and tea. Despite that, it is toxic to dogs.
