Relationship and biodiversity Introduction Botana curus is a valuable plant because it produces Curol‚ a compound used for treating certain kinds of cancer. Curol cannot be produced in the laboratory. Botana Curus grows very slowly and is on the endangered species list‚ so its ability to provide Curol in large quantities is limited. Species that are more closely related to Botana curus are more likely to produce the important substance Curol. Three similar plant species that are plentiful (X

sure the apparatus did not fall apart while in use. For the next step of the experiment gas chromatography was used to analyze the samples. In gas chromatography‚ it puts the solution into two separate phases‚ the mobile (non-polar) and the stationary (polar) phase. The mobile phase is where the solution is carried by an inert gas‚ in this case helium‚ through a column that is heated. For gas chromatography‚ the 3 tubes of solution that we received were individually tested to determine its composition

protein capture by Protein A affinity chromatography helps to remove a large majority of the impurities whicn include viruses and media components. At Stage 3‚ prior to cation exchange chromatography‚ the purified material in the eluted stream is then subjected to freezing‚ thawing and pooling. Stage 4 involves the Solvent/Detergent (S/D) viral inactivation which is the first dedicated viral clearance step. At Stage 5‚ the product undergoes cation exchange chromatography which aids in removing the S/D reagents

Thin-Layer Chromatography of Steroid Hormones Physiology Report 4.2 March 7th‚ 2012 By: Taryn Westerman Donald Fru Gloria Villarreal Julian Garcia Objective The purpose of this experiment was to test the solubility of various steroids in order to obtain more information about their structure. An unknown was also given to be included in the experiment. The test that was performed was thin-layer chromatography which required a glass plate. The known steroids used in this experiment were

substitution reaction to perform synthesis of 2-phenylethanol to get (2-bromoethyl)benzene. Using NaBr in an acidic solvent of H2SO4 with H2O present‚ this synthesis was possible. Subsequent evaluations using TLC and then analyzed samples by Gas Chromatography were done to evaluate the results. Using SN2 reactions‚ primary alcohol is going to be converted to alkyl halide. Since the reaction can be reversed‚ the strong sulfuric acid was to make sure the product would indeed be an alkyl halide. This is

INTRODUCTION Plant pigments consist of four main chemicals. These are Chlorophylls‚ The carotenoids‚ Anthocyanin and Betacaine. The aims of this experiment is to separate the plant pigment into different colours using solvents and column chromatography. The hypothesis of this experiment is that this plant pigment from spinach will contain the chlorophyll pigment or may contain the others too. Chlorophyll: Chlorophyll a is the main component of the plant pigments. This is used for the most

occurrence of an E1 mechanism in an alcohol dehydration reaction. Specifically this experiment involved the dehydration of 2-methylcylcohexanol by heating this alcohol in the presence of phosphoric acid and then to based on the results of the gas chromatography of the product to determine whether the alcohol exhibited the Evelyn Effect. The reaction taking place for both the Cis and the Trans isomers for Methylcyclohexanol are as follows: E1 Mechanism for Cis Methylcyclohexanol E1 Mechanism for

different color. Is soda really made of natural color from fruit? Is that safe to drink? Will that kill you? So there is science behind this. The colors of the soda is made of pigments. The fruit color will make the color of the soda brighter. Column Chromatography is a new technical method to separate the chemical inside the mixture. I can use this method to separate the dyes of the grape soda. The chemical mixtures in the grape soda will pour through the column and at the bottom the mixture will come out

Filtration is commonly the mechanical or physical operation which is used for the separation of solids from fluids (liquids or gases) by interposing a medium through which only the fluid can pass. Oversize solids in the fluid are retained‚ but the separation is not complete; solids will be contaminated with some fluid and filtrate will contain fine particles (depending on the pore size and filter thickness). Filtration is also used to describe some biological processes‚ especially in water treatment and sewage
