This study was undertaken with the objective of estimation the concentration of caffeine in seven brands of soft drink with the use of an analytical method. Caffeine is a central nervous system (CNS) stimulant and a bitter white crystalline xanthine alkaloid. Preparation: The different brands of beverages were procured from different companies like Red Bull, Pepsi, Cola-Cola, Mountain dew, XXX, Power-X, and Thumps-up. The caffeine content in the different beverages was determined by dilution by water and then absorbance was measured by U.V Spectrophotometer Shimanzu1800 compact by absorption at λ max 271.2 nm. The amount of caffeine was determined against the absorbance from the standard curve of caffeine in distilled water at same λ max in the range of 5-30 μg/ml. The highest concentration of caffeine was found in Power-X (46μg/ml), and remaining was found to be containing 44μg/ml to 20.5μg/ml. So Power-X could be called as a strongest CNS stimulant among all samples and it could be harmful for health. And the lowest concentration of caffeine was found in XXX (19.5μg/ml) so it could be weaker CNS stimulant among all samples.
