Experiment: The objective of this experiment is to determine the active ingredients contained within a series of over-the-counter painkillers using thin-layer chromatography or TLC. Introduction and Background: TLC is a quick and convenient chromatographic method for analyzing a mixture by separating its constituent compounds. Along with determining the number of components in a mixture‚ TLC can also be of aid in identifying unknown compounds. Separation of compounds is achieved as a partitioning

Preparation of the propolis extracts: the propolis sample of the Brazilian native bee species Melipona quadrifasciata was obtained in May‚ 2013 in the city of Blumenau‚ SC‚ Brazil (26 ° 54’21.3 "S 49 ° 04’49.1 "W). In order to obtain a hydroalcoholic crude extract (HCE)‚ 284.3 grams of propolis were pulverized and macerated in 70% ethanol (m m-1)‚ left in a dark chamber for 7 days at room temperature‚ filtered in vacuum and taken to complete drying in a rotary evaporator with reduced pressure.

Ethyl alcohol is a 2-carbon alcohol with a molecular formula of CH3CH2OH (Smith‚ 2014). Ethyl alcohol is an inebriating substance commonly found in alcoholic beverages. This substance acts as a central nervous system depressant and is commonly referred to as a “psychoactive drug‚” which is capable of altering brain function. This substance can be lethal if consumed in high doses. The amount of ethyl alcohol that is consumed can be quantified by blood alcohol content (BAC). BAC is measured as weight

Size Exclusion Chromatography Size Exclusion Chromatography (SEC) is the separation technique based on the molecular size of the components. Size exclusion chromatography is a kind of method to separate different size of molecules that put in solution. It was first discovered by two scientists who named Grant Henry Lathe and Colin R Ruthven. Both of them received the John Scott Award for this fabulous invention. There are various applications for Size exclusion chromatography such as biochemical

Chromatography – Analyzing Analgesics by TLC and Isolation of β-Carotene by Column Chromatography Introduction/Background: Flavonoids are an important group of additives that can be defined as pure substances either natural‚ extracted from raw materials or synthetic. Chromatography is the separation of two or more compounds or ions caused by their molecular interactions with two phases – one moving and one stationary (Weldegirma 2012). Three types of chromatography are used

2a: Infrared Spectroscopy and Analgesic Drug Identification Abstract: To be able to understand how organic soluble compounds could be isolated from non-organic components‚ a chromatographic separation process was used. The objective of the analgesic drug identification is to isolate the organic compounds/ active ingredients in an unknown drug. The identity of the drug was determined through melting point‚ percent recover‚ and Rf values. The comparable data for acetaminophen from the manufacturer

to the stationary phase than the mobile one‚ separation will be achieved. There are several different types of chromatography‚ such as thin layer chromatography (TLC)‚ gas chromatography (GC) and column chromatography. All the chromatographic methods are based on partitioning of molecules between a stationary phase and a mobile phase. In order to measure the amount of partitioning between the two phases‚ each compound has an unique Partition Coefficient (Kp)‚ which is defined as the

EXPERIMENT II: SEPERATION OF A MIXTURE OF SOLIDS PURPOSE: The purpose of this experiment was for me to become familiar with the separation of mixtures and solids and to learn separation techniques based on the chemical properties of a substance. PROCEDURE: Before beginning‚ I set up a data table to record data from the experiment. 1. Separating out the Iron a) I used my digital scale to determine the mass of my weighing dish. b) I emptied the entire mixture of solids from the plastic bag into
