Abstract

Caffeine(3,7-Dihydro-1,3,7-trimethyl-1H-purine-2,6-dione) is a widespread naturally occurring xanthine derivative found in a variety of plants but commonly found in coffee beans and tea leaves. Caffeine containing products have been consumed for hundreds of years for their taste, aroma and CNS stimulating properties. However there are many controversies and misconceptions about this chemical. Caffeine finds widespread applications in agriculture, in avian repellency, Military, as CNS stimulant and diuretic. The present investigation deals with isolation of caffeine from waste tea and characterization using UV-VIS and FTIR spectra.

Keywords: Caffeine, Tea, Alkaloid, FTIR, UV.
