TLDR
In this article, the triglyceride structures of Olive Oil and ester oil were calculated on the basis of 1,3-2 random distribution from total fatty acids and 2-monoglyceride fatty acids.
Abstract
Die nach der „1,3–2 random distribution” aus den Gesamtfettsauren und den 2-Monoglycerid-Fettsauren berechneten Triglycerid-Strukturen des Olivenoles und des Esteroles werden mit den durch Kombination von Silbernitrat- und Umkehrphasen-Chromatographie experimentell ermittelten Strukturen verglichen. Die Ergebnisse zeigen eine gute Ubereinstimmung mit den theoretischen Werten. Die Triglycerid-Struktur des Esteroles ist der des Olivenoles sehr ahnlich. The Triglyceride Structures of Olive Oil and of a Glyceride Mixture Synthesised by Esterification of the Olive Oil Fatty Acids The triglyceride structures of olive oil and the ester oil as calculated on the basis of 1,3–2 random distribution from total fatty acids and 2-monoglyceride fatty acids are compared with those found experimentally by the combination of silver nitrate and reverse phase chromatography. The results show a good agreement with the theoretical values. The triglyceride structure of the ester oil is very similar to that of olive oil.

Triacylglycerol Profiling by Using Chromatographic Techniques.

TL;DR: Application of gas-liquid chromatography, high-performance chromatography in normal and reversed phase mode, thin-layer chromatography and supercritical fluid chromatography for the qualitative and quantitative determination of TGs is reviewed and emphasis is put on those factors that are decisive for obtaining reliable quantitative data.

Die DC‐Trennung von isomeren und natürlichen Triglycerid‐Gemischen

H. Wessels, +1 more
- 01 Jan 1969 - 
TL;DR: In this article, the TLC-separation of mixed isomeric and natural triglycerides is discussed. But, the separation of natural triglyceride can not be effected to a large extent by a combination of reverse phase as well as argentation chromatography.

Further studies on the pancreatic hydrolysis of some natural fats

TL;DR: In this article, a series of animal and vegetable fats has been subjected to hydrolysis with pancreatic lipase and the triglyceride compositions of the original fats have been calculated by the method previously proposed by Coleman and Fulton.

TL;DR: The thin-layer chromatography makes possible the separation of the lipids in the different groups of substances and their qualitative analysis can be carried out in a short time as mentioned in this paper, and it is possible to investigate some chemical processes, such as oxydation-, saponification processes etc.
