Abstract
On the basis of dehydration reaction, the fatty acids of vitamin A esters were selectively separated from other coexisting lipid esters such as glyceride. Fatty acid composition was determined by the use of gas chromatography. Vitamin A esters in fish liver oils were composed of various saturated and unsaturated fatty acids from C14 to C24. Dominant members were palmitic and oleic acids. Polyenoic acid content was generally low as compared with that of other lipid esters such as glyceride.
