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

Johnson & Johnson then identified that 3 batches which had been released into the market had contained the affected batch of ibuprofen received from the vendor and recalled all bottles manufactured with this ibuprofen. This was estimated to be total of 200‚000 bottles of Motrin baby drops (Beasley‚ 2013)

Excedrin were caffeine‚ acetaminophen‚ and aspirin with Rf values of 0.11‚ 0.38‚ and 0.61‚ respectively. The lone active ingredient of Tylenol was acetaminophen with an Rf value of 0.39. The elution sequence obtained in the experiment is as follows: ibuprofen (least polar)‚ acetylsalicylic acid‚ acetaminophen‚ and caffeine (most polar). Purpose of Experiment: The objective of this experiment is to determine the active ingredients contained within a series of over-the-counter painkillers using thin-layer

Briefing Thin-layer chromatography (TLC) is an extremely valuable analytical technique. It provides a rapid separation of compounds‚ and gives an indication of the number and nature of the components of a mixture. TLC can also be used to identify compounds by comparison with known samples‚ to check the purity of a compound‚ or to monitor the progress of a reaction‚ an extraction‚ or a purification procedure. This experiment will introduce you to the mechanics of TLC‚ and the chemical principles

Thin-Layer Chromatography of Analgesics Abstract: In this experiment thin-layer chromatography (TLC) was used to determine the composition of an unknown mixture of analgesics given five references of AC‚ ASP‚ CAF‚ IBU‚ SAL‚ an unknown consisting of a mixture of three of the references‚ and two unknowns (6‚23) containing a single reference compound. The composition of the unknown mixture and two single unknowns were determined by spotting the reference compounds and the unknown compounds on two
