(JC) is a specie with the potential to use its oil as a biofuel and its quality is recognized by the composition of the fatty acids present. <strong><span class="CharOverride-4">Objective.</span> </strong>The objective of this work was the identification and quantification of fatty acids of JC genotypes of the Jatropha Colombia Collection.<strong><span class="CharOverride-4"> Materials and methods. </span></strong>During the years 2012-2014 the experiment was conducted in Espinal-Tolima, Colombia, in a randomized complete block design with fifteen genotypes. The lipid profile of the genotypes was determined by chromatography GC-MS and GC-FID. <strong><span class="CharOverride-4">Results. </span></strong>Ten types of fatty acids were detected in the oil: five saturated (myristic, palmitic, margaric, stearic, arachidic); three monounsaturated (palmitoleic, oleic and eicosenoic), and two polyunsaturated (linoleic and linolenic). The proportion was higher in monounsaturated acids (45.44 %) and polyunsaturated acids (34.18 %) and lower in saturated acids (20.37 %). In the monounsaturated, the oleic predominated (44.62 %); in polyunsaturated linoleic (33.95 %) and in saturated palmitic (12.41 %) and stearic (7.43%). The results found allowed the classification of JC oil as monounsaturated-polyunsaturated (oleic-linoleic), which coincided with what was reported worldwide. <strong><span class="CharOverride-4">Conclusion.</span></strong> Based on the lipid profile, it can be inferred that the oil of the fifteen genotypes evaluated in Colombia is suitable for use as biodiesel.</p> ER -
