1A: TLC Analysis of Analgesic Drugs Antonio Alarcon Chem 243a 9/06/07 I. Abstract In this lab, TLC plates were used to determine the compostion of common analgesics. As a result from the lab, Ibuprofen/Motrin turned out to be the least polar (highest Rf value). Caffiene/NoDoz turned out to be the most polar (lowest Rf value).

II. Introduction From a pharmacutical standpoint, both physiological and chemical properties must be understood to correctly utilize the mechanisms of action within any given medication. Physiological properties are attributed to the mechanisms of pain relief, anti- inflammation, and inhibiton. Chemical properties are attributed to the mechanisms of dosage, release factors (controlled, extended, delayed), and polarity. Of these above listed properties, chemical properties are of utmost importance, as they define the physiological effects. Within this lab, four “unknown” samples will be tested (Excedrin, Motrin, Tylenol, and NoDoz) and compared to four known samples within TLC plates. In doing so, the exact composition/ingredients can be identified as well as the polarity. Between the composition/ingredients and polarity of the given medications, polarity will be primarily focued upon. This is due to the fact that the TLC plate will highlight the most and least polar samples by the means of distance traveled (Rf value). Due to the
