1, 3, 7-Trimethylpurine-2, 6-dione (Caffeine) is a member of the class of compounds Organic chemists call alkaloids. Alkaloids are basic compounds which contains nitrogen. Caffeine is usually bitter in taste. Caffeine is physiologically active in human bodies and has mild stimulating effects to the central nervous system of human body. This study is focuses on the use of multiple extraction technique to isolate, purify and characterize the alkaloid caffeine from tea. Here is a comparison between many processes for extraction of caffeine from tea or coffee and finalized the polar-non polar solvent extraction. This study is helpful to determine an easily operable, more durable and cost effective technique to extract caffeine from tea. Selection of process/solvent must be done according to the process which gives highest % yield and which is more suitable for further processes.
