Fatty acid and triglyceride compositions of Indian tobacco seed oil ( Nicotiana rustica ) have been determined by combination of the techniques of systematic crystallization at low temperatures, pancreatic lipase hydrolysis, and gas liquid chromatography of methyl esters. The percentages of individual fatty acids were found to be linoleic 71.2, oleic 15.7, palmitic 8.4, and stearic 3.8. The special characteristic of the tobacco seed oil is its content of 37.4, 22.8, 4.9, 19.7, 9.3, and 3.3% of trilinolein, dilinoleoolein, dioleolinolein, dilinoleosaturated, linoleooleosaturated, and linoleodisaturated glycerides, respectively. In the present investigation, preference of linoleic acid over oleic acid for the 2‐position of glycerol moiety was not observed.
