A flow chart for the extraction and purification of Excedrin typically begins with the collection of the mixture, followed by the addition of a suitable solvent to dissolve the active ingredients (acetaminophen, aspirin, and caffeine). The solution is then filtered to remove insoluble impurities. Next, liquid-liquid extraction or solid-phase extraction may be employed to separate the active compounds, followed by crystallization or chromatography for further purification. Finally, the purified compounds are collected, dried, and characterized to ensure their quality and purity.
