Applications of GC-MS include drug detection, fire investigation, environmental analysis, explosives investigation, and identification of unknown samples. The present study also relies on use of GC-MS for detection and interpretation of compounds present in N. sativa oil samples. Fixed oil was obtained through column chromatography of ethyl acetate fraction. The oil samples were subjected to GC-MS analysis which showed 5, 18, 12 and 20 compounds in four fixed oil samples respectively. The major components were linoleic acid, methyl ester (35.5%), oleic acid, methyl ester (15.007%), palmitic acid, methyl ester (8.208%). 05 15 2018 38 42 10.22270/ujpr.v3i2.139 http://ujpr.org/index.php/journal/article/view/139 http://ujpr.org/index.php/journal/article/download/139/103 http://ujpr.org/index.php/journal/article/download/139/316 http://ujpr.org/index.php/journal/article/download/139/103 http://ujpr.org/index.php/journal/article/download/139/316
