The fixed oils  from the seeds of canola and rape plants (N.O. Cruciferae) have been characterized and studied for their fatty acid composition by GLC. The two  oils  were compared and it  we   found that mustard oil (rape seed oil) samples  contained 41.5-45.7% erocic acid other than palmitic acid (1.8-4%), stearic acid (0.34-11%), oleic acid (15.6-24,3%), linoeleic acid (12.0-13.7%), linoelenic acid (1.%2.1%), arachidic acid (2.,2.9%) and lignoceric acid (4-4.7%). The canola oil contained only 0.0-1.7% crucic acid other than myristic acid (0.1- 0.4%), palmitic acid (5.5-11.5%), stearic acid (1.6-3.7%), oleic acid (48.9-60.6%), linoleic acid (3.7-26.8%), linolenic acid (6.4-9.7%), arachidic acid (2.0-2.9%), and behenic acid (0.34-0.81%).
