Fractionation of cholesterol esters by thin-layer chromatography

Fractionation of Cholesterol Esters by Thin-layer Chromatography.

The fractionation of cholesterol esters by silicic acid chromatography.

Within recent years, the technique of silicic acid chromatography to separate complex mixtures of lipides has been developed widely (1-3). At the present time it is possible to resolve some eight different classes of lipides ranging from hydrocarbons to phospholipides on a single column (4). In addition, this procedure has been used to separate classes of phospholipides from one another (5). Ou...

Doss: Thin-layer chromatography of porphyrin methyl esters

Thin-layer chromatography methods on the preparative and analytical scale are presented for the separation of porphyrin methyl esters according to the number of ester groups in each porphyrin. Complete and sharp separations are obtained on silica gel glass plates or aluminium cards run in benzene-ethyl acetate-methanol solvent systems. Dicarboxylic porphyrin esters from proto-, deuteroand hemat...
