Triglyceride composition ofSesamum indicum seed oil

Abstract

The fatty acid composition of Sesamum indicum seed oil was determined by gas–liquid chromatography. The percentages of individual acids were found to be: palmitic, 11; stearic, 6; arachidic, 1; oleic, 43; linoleic, 39. Triglyceride composition was calculated from the fatty acid compositions of the native oil and of the monoglycerides produced from it by pancreatic lipase hydrolysis. The oil is composed of 8, 41 and 51%, GS2U, GSU2 and GU3 respectively. Analysis by special thin-layer chromatography combined with densitometry also indicated similar triglyceride composition for the sesame seed oil. Changes effected on the triglyceride composition by randomisation were also determined by both methods of analysis.
