Determination of Triacylglycerols, Fatty Acids and Total Lipid Content in Oil of 2 Macrotermitinaes Varieties from Congo

Victor N`Goka and Diane Julien-David

The triacylglycerols and fatty acids composition of the oils of the Bellicositermes natalensis Haviland obtained from two different regions of Congo were qualitatively and quantitatively determined by gas chromatography/SM. This insects contained oil in the range of 48-53% dry matter, comparable with oleaginous plants like palm tree (45-50%), peanut (45-54%), more than soya (18-25%) and sunflower (22-50%). Levels of lipid content probably could be considered sufficient for economic industrial exploitation for every usage like human’s consumption and medical usages. The pre-dominant triacylglycerol was palmitoyl-Oleoyl-Palmitoylglycerol (POP), 15.6-19.2%; followed by Palmitoyl-Oleoyl-Stearoylglycerol (POS), 14.6-18.1%, the minor were stearoyl-oleoyl-stearoylglycerol (SOS), 1.7-1.9%. The pre-dominant fatty acid was oleic (C18:1) and its content was about 57-60%, followed by palmitic acid (28-30%), stearic acid (9-11%), palmitoleic acid (3.5-4.0%), myristic acid (0.4%) and undetermined acid (0.2%). High qualitative similarity with butter fatty acids composition was observed and more, the content of this oil in monounsaturated fatty acids (60.5-62.5%), is near of the favourite olive oil which is 67.2%.
