“…In this study, the values of β‐sitosterol, stigmasterol, and campesterol, quantified in response to 160 kg P ha −1 , were 150.17, 34.93, and 12.74 mg 100 g −1 , respectively (Table ). Santos et al measured 103.28 mg 100 −1 of β‐sitosterol and 54.09 mg 100 −1 of campesterol. Lechner et al reported average values of 232.8, 4.8, and 101.2 mg 100 g −1 of β‐sitosterol, stigmasterol, and campesterol, respectively, in crambe oil.…”

The objective of this study was to determine parameters of crambe oil culvtived with phosphorus (P), with respect to oil content, fatty acid composition, minor compounds, and total antioxidant activity. The experiment followed a randomized block design, with five doses of P (0, 40, 80, 120, and 160 kg P ha−1) and four replications. All results were subjected to analysis of covariance (ANCOVA) 5% significance. The P dose had a negative linear association with δ‐tocopherol and total antioxidant activity, and a positive association with stigmasterol and total carotenoids. P influenced the concentrations of β‐sitosterol and campesterol, whereas the remaining variables (content, α‐tocopherol, β + γ‐tocopherol, fatty acids, total phenolic compounds, and chlorophyll a) were not affected. This study show a positive effect the concentrations of compounds that act as antioxidants in crambe oil, which can influence with its oxidation stability. Practical applications: Is relevant the studies concerning the oxidative stability of inedible vegetable oils, such as crambe, in terms of the composition of antioxidants and fatty acids, as this affects the conservation, storage and refining costs, and the quality of the products, considering the many uses of this oil, such as biodiesel, lubricants, corrosion inhibitors, synthetic rubber, plastic films, nylon, and adhesives, among other products. Phosphorus (P) plays an important role in synthesis processes performed by plants such as, functions in cell energy transfer, respiration, and photosynthesis, with an emphasis on processes related to the flow of energy and products stored in grains. In this study, P influenced on the concentrations of compounds such phytosterols and carotenoids, which shows a positive effect in concentrations of compounds that act as antioxidants in crambe oil.

“…The extraction process is safe and efficient, provides good selectivity and environmental compatibility and does not damage the bioactive compounds of materials, nor does it result in the formation of benzo[ a ]pyrene as in the case of hexane extraction . SBE is a continuous counter‐current process; after extraction, the solvent is removed completely by system depressurization at low temperature and can be recovered . Thus we chose the SBE method to extract fragrant red pepper seed oil (FRPSO) in this study.…”
