Soybean is the main oilseed cultivated in the Middle-west region of Brazil, once geoclimatic conditions favor its cultivation and underexplored species such as crambe, oilseed radish, and niger too. These species can be alternatives to eliminate the conflict between food and energy production, so the study aimed to evaluate and compare the fatty acids content of soybean, crambe, oilseed radish and niger oils by gas chromatography with flame ionization detector using two quantification methods, followed by multivariate statistical analysis to determine the similarity between the selected species and to provide safe information for the best selection and application of these oilseeds. The oil content in crambe, oilseed radish and niger seeds were 44.7% (m/m), 42.45% (m/m) and 28.19% (m/m), respectively. The major fatty acid in niger and soybean oils was linoleic acid (66.9% and 52.07% m/m, respectively), in crambe and oilseed radish was erucic acid (65.29% and 33.54% m/m, respectively). In addition, for saturated fatty acids, the presence is minor ( |
