The purpose of module E is to learn several DNA techniques in the lab including DNA purification with solubility and absorption‚ plasmid transfection of E.coli‚ colony screening by PCR and quantitative PCR. First part of the experiment E1 show the purification method of DNA through solubility. E. coli lysate mixed organic solvents to purify the DNA present in solution. First‚ the lysate was mixed with phenol/chloroform‚ then vortexed‚ and centrifuged. We extracted the aqueous layer and combined

Isolation of Acetyleugenol (Clove Oil) from Cloves Purpose In this experiment‚ you will obtain the essential oil from cloves by steam distillation. You will then separate a component (acetyleugenol) from the oil by liquid-liquid extraction. Finally‚ you will isolate the acetyleugenol by using a rotovap for reduced pressure distillation‚ which will remove the organic solvent (dichloromethane). Background Whole cloves contain between 14% and 20% by weight of essential oils‚ but

EXTRACTION OF CAFFEINE FROM TEA LEAVES ABSTRACT Caffeine extraction from the commercial tea leaves (Lipton Yellow Label Tea) that was done is multiple extraction. 4 tea bags were used in the experiment; tea leaves were weighed having 8.5333 grams. The leaves were boiled in a beaker with 150ml of water; the aqueous tea extract was transferred in a seperatory funnel mixed with DCM (20ml)‚ done thrice. The DCM layer was washed with 20ml 6M NaOH in the seperatory funnel; the organic layer

Introduction Extraction involves dissolving a compound or compounds either from a solid into a solvent or from a solution into another solvent. Extraction is a method used to purify a substance by removing the impurities that was added to it. A solvent- solvent extraction is a type of extraction that is most commonly done by using two substances that are typically insoluble with each other. An acid-base extraction is a solvent-solvent extraction‚ in almost every case one of the solvents is water
