Diethyl Ether Lipid Extraction

Petroleum ether is also known as benzine painter s naphtha petroleum naphtha naphtha astm petroleum spirits x4 or ligroin.

Diethyl ether lipid extraction. Diethyl ether is considered a good organic extracting solvent because it has a low polarity according to the university of alberta s organic web chem. Diethyl ether is a more efficient solvent in general danger of explosion fire hazard and a higher price are among the reasons for selection of low boiling petroleum ether 35 to 60 c for lipid extraction. Extraction time impacted surface lipid recovery for seedling leaves extracted in the hexanes diethyl ether 90 10 solvent system. One is usually water or water based and the other an organic solvent.

Chemically it is. Due to its greater non polarity petroleum ether will yield a more specific extract than diethyl ether because it will only extract the most polar molecules. Therefore reducing moisture content of the samples may facilitate lipid extraction. Diethyl ether is hygroscopic and becomes saturated with water and thus inefficient for lipid extraction.

The lipid mixture is usually dissolved in diethyl ether and then four volumes of cold anhydrous acetone is added to precipitate the phospholipids 33. An application that has benefited particularly from the igp system is lipid extraction from food and plant materials using the highly flammable solvent diethyl ether. Blend ratio of petroleum ether and diethyl ether for lipid extraction. Although recoveries of hydrocarbons fig 5a aldehydes fig 5c and alcohols fig 5d were not impacted by extraction time in either solvent fatty acid recovery was significantly impacted by extraction time in hexanes diethyl ether 90 10 r 2 0 87 p.

When utilizing extraction solvents for liquid liquid extraction two solvents must be used. Hexane diethyl ether. Effects of subcritical solvents propane dimethyl ether dme and their 1 1 mixed solvents and extraction temperatures 30 c to 60 c on oat lipids and phospholipid extraction were investigate. A further improvement was made in 1914 when a mixture of ethanol ether 3 1 was used for lipid extraction bloor wr j biol chem 1914 17 377.

The aim of a typical diethyl ether extraction procedure is to separate cellular or fluid lipids from other constituents including proteins polysaccharides small molecules api s amino acids sugars and to preserve the. On the other hand endogenous water and the solubilizing effects of other lipid components may permit acetone to extract more phospholipids from animal or plant tissues than might be predicted from a knowledge of the solubility of lipid.
