The Chemistry of Lipids Experiment #8 Objective To observe the solubility of lipids in polar and nonpolar solvents and to compare saturated and unsaturated fats in their chemical reaction with bromine. The percent fat in a food will be determined by extraction of the fat and weighing it. Introduction Lipids‚ by definition‚ are natural substances that do not mix with water but dissolve in organic solvents. There are several classes of lipids‚ including: fatty acids‚ waxes‚ triacylglycerols

1. Introduction Plumbago zeylanica L. belonging to the family Plumbaginaceae is an important plant of medicinal value. In the Arabian Peninsula‚ it is mainly distributed over Oman‚ Yemen and the Southwestern region of Saudi Arabia. The use of the roots of P. zeylanica for treating skin problems has been recorded by early Muslim physicians. P. zeylanica is greatly valued in Ayurveda for treatment of cough‚ asthma and gastrointestinal disorders. In Sushrutha Samhitha it has been described as antiseptic

Next‚ go to the fume hood and add 500 L of chloroform to each tube. Spin the tubes in a centrifuge set at the highest rpm for 2-5 minutes. 4) Return to the fume hood and extract the supernatant/aqueous (top) solution from the tube using a pipetmann. To do this start by setting the pipetmann

2.2.3 P. guajava :- P. guajava leaf extracts were subjected to inhibitory effect of glucose utilization using specific standard in vitro procedure. Plant material was subjected to the extraction preparation by soxhlet apparatus by using various solvents such as aqueous‚ ethanol‚ chloroform‚ petroleum ether and hexane. The various kinds of phytochemicals were detected and then in vitro antidiabetic activity of P. guajava were detected by using alpha amylase and alpha glucosidase enzyme in an in vitro

procedure in order to break up the cell membranes and other structures that would make extraction difficult. In this experiment‚ petroleum ether was used as the solvent due to its low boiling point‚ relatively non-toxic nature (when compared to chloroform or methanol)‚ and of course because it is quite non-polar. When talking about ether‚ two kinds can be used in lipid extraction: anhydrous diethyl ether CH3CH2OCH2CH3 and petroleum ether‚ which is a mixture of pentane (CH3CH2CH2CH2CH3) and hexane

SAMPLE PREPARATION METHODS FOR LIQUID SAMPLES Table of Contents SAMPLE PREPARATON Analytical procedures consist of numerous stages‚ the most important of which is the collection of a sample and its preparation for analysis as samples are usually not in a suitable form for direct introduction into analytical instruments (Tankiewicz et al.‚ 2011). Sample preparation can be thought of as any treatment that the sample is subjected to following its collection‚ prior to its analysis
