What is Caffeine Extraction from Tea Leaves about?

This study extracted caffeine from tea leaves (Thea sinensis) through filtration, multiple extractions with dichloromethane and sodium hydroxide, and evaporation. Three tea bags weighing 6.196 grams were used. After isolating and evaporating the crude caffeine, 0.0703 grams of caffeine was obtained, yielding a 1.13% extraction rate. The goal was to demonstrate the process of isolating a natural compound from a plant source through separation and purification techniques.
