Caffeine is a bitter, white crystalline xanthine alkaloid and a stimulant drug. It is found in varying quantities in the seeds, leaves, and fruit of some plants. Generally tea is made from the leaves of an Asian evergreen known as Camellia sinensis. Caffeine is a prime constituent of tea. The presence of caffeine in plants helps to prevent them from insects and other herbivores with the compound’s bitter taste and stimulating qualities. The growing buds and young leaves of tea plants manufacture the highest amounts of caffeine. Caffeine is the only legalized central nervous system stimulant to be used among humans. This experiment was conducted to estimate the total amount of caffeine in used tea leaves of roasted tea and green tea. 5g of roasted tea from three different sources Darjeeling, Assam and Nilgiri obtained caffeine 0.1g, 0.058g and 0.060g respectively. 5g of green tea from three different sources Darjeeling, Assam and Nilgiri obtained caffeine 0.040g, 0.037g and 0.021g respectively. The objective of this experiment was to extract caffeine from roasted tea and green tea and to check the quantity of different variety of roasted and green tea safe for human consumption.
