| Abstract: | The growing demand for sustainable and eco‐friendly alternatives to petroleum‐based lubricants has prompted interest in plant‐derived oils as a potential raw material for the synthesis of biolubricants. This study explores the utilization of microwave‐assisted Soxhlet extraction (MASE) for the efficient recovery of oil from the three species of Brassica carinata seeds "Tesfa," "S‐67," and "Holeta‐1." Their physicochemical properties, fatty acid profiles, and functional groups were evaluated, alongside testing for stability and storage conditions for biolubricant application. MASE demonstrated efficient oil recovery, with yields varying between 33.4% and 44.5%, influenced by microwave power, extraction duration, and solvent‐to‐solid ratios. Among the varieties, Tesfa and S‐67 exhibited marked sensitivity to these parameters, whereas Holeta‐1 displayed consistent performance under varying conditions. Compositional analysis revealed high carbon content (75.50%–76.10%), minimal nitrogen, and notable unsaturation levels. Erucic acid (42.17%–44.17%) and oleic acid (13.33%–26.97%) dominated the fatty acid profiles, aligning with traits desirable for lubricant formulation. FTIR and GC‐MS analysis confirmed the presence of ester groups and unsaturated hydrocarbons, emphasizing their suitability for biolubricant synthesis. Stability assessments highlighted Holeta‐1's superior resistance to oxidative degradation, while Tesfa and S‐67 required controlled storage conditions to mitigate temperature and light‐induced breakdown. These findings highlight the potential of Brassica carinata seed oils as sustainable feedstocks for biolubricant production, with tailored processing strategies required to enhance their performance and stability for industrial applications.
