Post Lab Report Experiment 3 - Chromatography – Analyzing Analgesics by TLC and Isolation of β–Carotene by Column Chromatography Chemicals 1. Acetaminophen (C8H9NO2) 2. Aspirin (C9H8O4) 3. Caffeine (C8H10N4O2) 4. Ibuprofen (C13hH18O2) Introduction In this experiment‚ several analgesics were analyzed by Thin Layer Chromatography (TLC) and the composition of an unknown tablet was identified.

The result show us that the Caffeine has more polarity than other compounds because it stays in stationary phase which has high polarity. In contrast‚ the Ibuprofen is less polar‚ because it travels with the solvent which is less polar also. Therefore‚

purpose of this experiment is to determine the components of an unknown drug and identify it as one of six (6) commercial drugs by using thin-layer chromatography. I added approximately a quarter of a tablet of acetaminophen‚ aspirin‚ caffeine‚ ibuprofen‚ salicylamide‚ and the unknown (#19) to separate test tubes containing 2.5mL of dichloromethane. I noticed that my unknown was a coated tablet. Each test tube was swirled until the greatest amount of each solid was dissolved. Each solution was spotted

She was not evaluated by a rheumatologist. Despite scheduled APAP and ibuprofen throughout the day‚ the pain has not decreased much. The pain seems to be cyclical; it is very bad for a period of weeks‚ and then it wanes over time. It is also worse in the summer. She thinks the rashes she gets now and then on her face and arms

Five COX inhibitors were used to validate the assay‚ indomethacin‚ aspirin‚ naproxen‚ ibuprofen‚ and the arylsulfonamide NS-398‚ all with different COX selectivity and time dependency. Time-dependent inhibition was determined by comparing the inhibition‚ with and without preincubation of enzyme and inhibitor. Two flavonoids‚ (+)-catechin
