Extraction, Purification and Partial Estimation of Caffeine from Marketed Tea and Coffee Powder

The objective of present work is to extract, purify and partially estimate caffeinefrom marketed coffee and tea powder.UV-Spectrophotometric method was evolved using chloroform as solvent. The evolved method was standardized in terms of validation parameters such as simple, sensitive, linear as per ICH Q2 (R1). Guidelines for analysis of caffeine in marketed tea and coffee powder.Caffeine was extracted from different brands of marketed coffee and tea powder and was analyzed through different analytical methods like UV-Spectroscopy, Iodometric Titration, Solubility, Melting point, Thin Layer Chromatography.
