AND PARACETAMOLPRACTICAL REPORT ON THE ISOLATION AND IDENTIFICATION OF CODEINE AND PARACETAMOL AIM: To extract codeine and paracetamol from its tablet by solvent extraction and tentatively identify in comparison to standards using Thin Layer Chromatography. INTRODUCTION: Codeine or methyl morphine‚ an alkaloid‚ was first isolated in 1832 from raw opium. It concentration ranges from 0.2% to 0.8%. Mostly used for its analgesic‚ anti-tussive and anti-diarrheal capabilities (Tremlett‚ Anderson

Title: Liquid Chromatography Author: Gloria Contreras Lab Partner: Jose Montanez Instructor: Teresa Potter Date Work Performed: January 13‚ 2015 Date Submitted: January 20‚ 2015 Abstract: In this lab‚ liquid chromatography is used to separate the Red 40 and Blue 1 dyes inside of grape flavored Kool-Aid. It was determined that the 5% isopropanol will remove the Red 40 dye from the stationary phase. The 28% isopropanol will remove the Blue 1 dye from the stationary phase. The more
