  ABSTRACT: A method to identify triglycerides, separated by reversed-phase thin-layer chromatography on silanized Kieselguhr G layers using densitometric data only, is described. Different triglyceride mixtures, containing components with partition numbers in the range 44-56, have been scanned. A linear relationship between the partition numbers of the zones and the maximum-to-maximum distances of the corresponding peaks, relative to the peak of the zones with partition number 48, has been found. The validity of this equation has been confirmed experimentally for triglycerides with partition numbers in the range 30-46. The method allows the identification of the triglyceride components of a mixture by their partition numbers, provided only one partition number is known or can be determined independently. An example concerning sunflower oil triglycerides is presented.

  ABSTRACT: The resolution of triglyceride mixtures on a Kieselguhr G layer silanized with dimethyldichlorosilane and the mobile phase acetone-acetonitrile-water under different chromatographic conditions has been investigated. The influence of the water content on the separation has been studied. Each triglyceride mixture needs a mobile phase with a definite polarity, which depends on the partition numbers of the triglyceride components. Since a linear correlation between the partition number and the water content was observed, prediction of the mobile phase composition for any triglyceride mixture is possible, provided the partition numbers of the components are known. The chromatographic conditions found can be applied for resolution of triglyceride groups with partition numbers ranging from 30 to 52, in different triglyceride mixtures.
