Abstract
The aim of this research was to compare which of the two methods: soxhletation-sublimation orrefluxrecrystallization with two solvents, more efficient to isolate and purify caffeine form coffea Arabica bean powder. The first method was performed using soxhlet apparatus for continuous solid-liquid extraction followed by sublimation, while the second method was done using reflux with round-bottom flask, followed by recrystallization with two solvents -acetone and petroleum ether. Identification of isolated substance was conducted by thin layer chromatography (TLC) and Fourier transform- infrared spectrophotometry (FTIR) methods. From the results of this research it could be concluded thar soxhletation-sublimation method was more efficient to isolate and purify caffeine from coffea Arabica bean powder than reflux-recrystallization with two solvents.
