Extraction of Caffeine from Tea Leaves using Dichloromethane (CH2Cl2) Abstract The extraction of caffeine (C8H10N402) was done in two parts. The first procedure used was solid-liquid extraction which was done by boiling the tea leaves in 100 ml. distilled water for 5-10 minutes. The filtrate was acquired and was extracted again by liquid-liquid extraction using dichloromethane (CH2Cl2). The combined DCM (CH2Cl2) was washed and dried to yield crude caffeine. The crude caffeine was purified
