The purpose of this experiment was to identify the generic name of the unknown drug through thin-layer chromatography analysis. By comparing the Rf values obtained from each TLC plate, it was deduced which components were present in the unknown drug. Through comparison of Table 1 and Table 2, Unknown A was identified as B.C. Tablets. Salicylamide was evident in the unknown substance due to the distinct blue color that was present in both the unknown spot and the salicylamide spot; the similar Rf…

The variable located at the left side of the diagram, the effect of malunggay and ginger root extracts is the independent variable which in being manipulated for the dependent variable, the time spent in treating the sample infected by trichophyton rubrum. The main purpose of this study is to produce an organic antibacterial treatment for Trichophyton rubrum using Malunggay (Moringa oleifera) and Ginger (Zingiber officinale). Specifically, this study aims to answer the following: 1. In which…

Beta-Carotene from Plant Leaves Yokoyama Yuri B1 (A0142349E) 1. Aim: a) To separate beta-carotene and chlorophyll via column chromatography. b) To analyse the contents of the plant extract as well as the separated beta-carotene and chlorophyll via thin layer chromatography (TLC) c) To analyse the absorption peaks of both beta-carotene and chlorophyll using UV-Vis spectroscopy 2. Results: Fig 1. UV-Vis spectroscopy results for S2 (Beta-Carotene extract) Wavelength at peak/ nm Peak obtained/ A…

Isolation of Component Via Extraction Objective: Separation of organic acid from a neutral compound using liquid/liquid extraction. Experimental: Similar to the “Thin Layer Chromatography” experiment, a TLC plate was ran with 2 ml of EtOAc and 8 mL of hexane in the jar. The Rf value was calculated using the formula located in the data for all the TLC plate. The mixed compound that was dotted on the TLC plate had 0.300 g of the impure benzoic acid and 10 mL of dichloromethane. A 50 mL flask…

Abstract The primary goal for this laboratory experiment was to synthesize, purify, and identify p-nitroacetanilide using acetanilide as the starting material. To test for the purity and identification of our desired product, we gathered data from: Thin Layer Chromatography (TLC), Melting Point (MP) range, Infrared (IR) spectrum, Gas Chromatography Mass Spectroscopy (GC-MS), and Proton Nuclear Magnetic Resonance (1H NMR). TLC plate indicated the formation of our pure product due to the…

Methods We began this experiment by laying out the needed materials to find the chromatography of Skittles Sweets and Sours and Crayola markers. Using a ruler and a pencil, a line was drawn on all thirty chromatography strips 1.5 centimeters from the bottom of the paper. This was to ensure that the starting point for each chromatography process was consistent. The chromatography of the skittles was found first. We began by pouring water into a cup. A pipette was used to transfer fifteen…

phase and the stationary phase have similarities or differences that affect the overall interaction between each other and the analyte. Separation of the individual components is achieved because each component travels at different rates. Likewise, Thin Layer Chromatography (TLC) is a chromatography technique where separation of the components in a mixture occurs on a sheet of glass,…

Experiment 5 Synthesis and NMR Spectroscopy of ethyl cinnamate Introduction: Wittig reactions involve the stereoselective synthesis of olefins from phosphonium ylides and aldehydes or ketones, where the carbonyl bond is converted to an alkene double bond.1 The variety of suitable reagents and the relatively mild experimental conditions facilitate their industrial applications, such as the synthesis of epoxides, esters, carotenoids and vitamin A.2,3 Specifically, the ester ethyl cinnamate is used…

Slime is made by mixing together borax, glue, and water. Depending on the amount of borax added to the mixture will determine the density of the slime. For our experiment in class the independent variable was the borax. The dependent variable was slime. The control group was glue. It was important to keep the amount of glue, borax, and water constant throughout the experiment. In an experiment conducted in class it was hypothesized that the more borax added the denser the slime will be.…

Identification of Analgesic Drugs by Thin-Layer Chromatography 1 (a) In thin-layer chromatography alumina or silica is used as the adsorbent material. (b) The filter paper is placed inside the beaker during separation to act as an adsorbent medium. (c) The ultraviolet lamp is used after TLC separation to illuminate the TLC sheet. (d) Aspirin, acetaminophen, and caffeine are components of analgesic drugs examined in this experiment. 2 A 6cm by 10cm pre-coated TLC sheet will be obtained. On the…
