Abstract

Whether there are differences of fatty acid composition or content in the different samples of tomato seeds,the fatty acids in crude fat which was extracted by Soxhlet extractor from 6 tomato seed samples were determined by gas chromatography(GC) after modified to methyl esters,with 37 kinds fatty acid methyl ester mixture.The results showed that:the content of dry matter in tomato seed samples was 52.48% on average,and the content of crude fat was 32.82% on average.There were significant differences on total fatty acids among tomato seed samples.The relative content of fatty acids in tomato seed samples also had certain differences.The major fatty acid components in seeds identified were as follows:hexadecanoic acid 11.16%～12.54%,stearic acid 3.82%～5.12%,oleic acid 17.32%～29.85%,linoleic acid 52.63%～64.12%,linolenic acid 1.45%～2.17%.
