ABSTRACT

Caffeine (3,7-dihydro-1,3,7-trimethyl-1H-purine-2,6-dione or1,3,7-trimethyl xanthine) is a well-known compound that occurs in nature in coffee, tea, cola nuts, mate leaves and other related natural products. Caffeine at sub milli molar concentrations exerts a wide variety of pharmacological effects on different organisms and has long been known to have numerous actions, including inhibition of phosphodiesterase’s, thereby increasing intracellular cAMP, direct effects on intracellular calcium concentrations, indirect effects on intracellular calcium concentrations via membrane hyperpolarization. Our study mainly focused on to isolate caffeine from Tea Leaves/Powder collected from different Eastern Himalayan Region of India and characterized by different Physicochemical, Chromatographic and Spectroscopical technique by comparing them with a standard caffeine which was available commercially.

Keywords: Caffeine, Isolation, Chromatography, Infrared spectroscopy, Retention factor.
