title: [Gas chromatographic determination of individual high molecular weight fatty acids in the composition of lipids].
abstract: A rapid and precise method is suggested for quantitative determination of highly molecular fatty acids in a sample either in the esterified (mono-, di- and triglycerides, cholesterol ethers, and phospholipids) or in the non-esterified state, as well as like salts of fatty acids (soaps). Methyl ethers of fatty acids have been obtained by immediate methanolysis of the sample studied. The method advantages are both indices of the amount of the internal standard added to the sample of concern and possibility to determine highly molecular fatty acids in any sample taken either from plants or from animals.
