TL;DR: In this paper, a procedure involving thin layer chromatography on silica impregnated with silver nitrate is described, which makes possible the separation of synthetic and natural glyceride mixtures into classes according to their degree of unsaturation, and within those classes the resolution of certain isomeric unsaturated glycerides.
Abstract: The paper describes a procedure involving thin layer chromatography on silica impregnated with silver nitrate, which makes possible the separation of synthetic and natural glyceride mixtures into classes according to their degree of unsaturation, and within those classes the resolution of certain isomeric unsaturated glycerides. The separations depend upon the ability of compounds having an olefinic double bond to form co-ordination complexes with the silver ion.

Journal ArticleDOI
TL;DR: The possibility of separating lipid materials on the basis of the number, type, and position of the unsaturated centers they contain, by virtue of the complexing of these unsaturated bonds with silver ions, provides a relatively recent but now very important addition to the range of separatory methods available to lipid chemists and biochemists.

TL;DR: In this article, a method for the analysis of isomeric monoglycerides by thin-layer adsorption chromatography was developed for the separation of 1-and 2-monoglyceride.
Abstract: A method has been developed for the analysis of isomeric monoglycerides by thin-layer adsorption chromatography Isomeric monoglycerides are separated on silica gel impregnated with boric acid; a mixed solvent system is used The interaction of hydroxy compounds with boric acid allows the separation of 1- and 2-monoglycerides which cannot be resolved on silica gel alone In order to make the method quantitative, the resolved components are charred and their spot densities measured Glycerol, fatty acids, diglycerides, and triglycerides do not interfere The method does not induce isomerization
