Abstract The aim of this research paper is to investigate the extraction and analysis of caffeine content from various brands of tea leaves marketed in India. Caffeine, a natural alkaloid, is a well-known stimulant widely consumed around the globe, particularly in tea and coffee. With increasing tea consumption in India, it becomes important to understand its caffeine content, which may vary significantly across different tea types and brands. This research adopts various methods of extraction and analysis to determine the caffeine content in black, green, oolong, and decaffeinated teas. Using liquid-liquid extraction and thin-layer chromatography (TLC), this study evaluates the amount of caffeine in 10 tea brands available in the Indian market. The results indicate significant variability in caffeine concentration across different types of tea, with black tea containing the highest concentration, followed by oolong and green tea. This paper also evaluates the efficiency of the extraction methods used in isolating caffeine, providing insights into the most effective techniques for obtaining caffeine from tea leaves. The findings have important implications for both consumers and producers in the tea industry, offering a deeper understanding of the caffeine content in commercially available tea products. Additionally, this study discusses the health implications of caffeine consumption, including its positive and negative effects on the human body.
