ABSTRACT
Analysis of fatty acid composition in fixed oil extracted from Sterculia foetida Linn. (Sterculiaceae) seed was done with the help of GC-MS. The structural identification was done by preparing FAME of the fixed oil and then subjected to GC-MS wherein Flame Ionization Detector was used. The oil constituted of 7 fatty acids whose carbon chain length, degree and position of unsaturation were determined from the characteristic ionization and fragmentation of FAME resulting from GC-MS electron impact, chemical ionization modes. The fatty acids found in the oil were methyl esters of tetradecanoic acid (Myristic acid) (1.65%), hexadecanoic acid (Palmitic acid) (11.87%), 9-Octadecenoic acid (Oleic acid) (20.50%), 7, 10-Octadecadienoic acid (Linoleic acid) (20.50%), 8-(2-Octacyclopropen-1-yl)octanoic acid (Sterculic acid) (6.76%).
