Chromatography of polar triglycerides on silicic Acid Columns

Abstract

Triglyceridcs containing polar fatty acids are resolved by silieic acid chromatography into molecular species containing increased amounts (if the polar acids. Natural fats like isano, oiticiea, castor, or kamala seed oils with both nonpolar fatty acids and polar hydroxy or keto acids have been resolved into component glyeerides according to the degree of polarity. Silicie acid chromatography offers a means of obtaining specific glyeerides from fats for detailed st/ldies on glyceride composition and structure.

The detection and determination of synthetic emulsifiers in foods

“…The technique of separation by elution with increasingly polar solvents can be used to resolve mixtures of polar glycerides, i.e. glycerides containing hydroxy and ketoacids (Evans et al, 1967). Other methods available for the analysis of mono-, diand triglycerides include molecular distillation (Privett,Blank & Lundberg,196 1) and charring of chromatograms (Privett & Blank, 1962).…”

Analysis of seed oil from ricinus communis and dimorphoteca pluvialis by gas and supercritical fluid chromatography

“…The method is fast and qualitative, but not suitable as a quantitative technique. Liquid chromatography (LC) has been used to separate the acylglycerols in the oil from D. sinuata with a fair resolution and with the possibility to analyze the collected fractions separately (17).…”
