This study aimed to carry out the extraction and chemical characterization of oil from crambe treated with resistance inducers during its cultivation to promote greater efficiency in the defense system of plants. For this purpose, Agromos® and Ecolife® inducers were applied at rates of 0.5 and 1.0 L hectare−1 during crambe cultivation. Crambe seed oil was obtained in a Soxhlet extractor using n-hexane as a solvent and the oils were characterized in terms of fatty acid composition and minority compound contents (phytosterol and tocopherol). The oil obtained from seeds without the application of inducers (control) was also characterized. We determine the oxidative stability of oils with inducer application that presented higher minority compound contents. Crambe seeds that received the treatment with the Agromos® resistance inducer had higher oil content. However, in general, the fatty acid profile of the obtained oils was similar and showed a predominance of erucic and oleic acids (which represent ~82% of the composition). The application of the Agromos® inducer allowed obtaining seeds that provided oil with higher contents of phytosterols and tocopherols and higher oxidative stability.
