AB A wheat bran oily extract obtained with supercritical carbon dioxide at 25.0   0.1 MPaand 40   2  C has been analyzed in order to determine some valuable bioactive compounds asalkylresorcinols,  -linolenic acid, steryl ferulates, tocopherols and phenolic compounds, which levelswere around 47, 37, 18, 7 and 0.025 mg/g oily extract, respectively. To our knowledge, this is thefirst time that the presence of steryl ferulates has been observed in a supercritical fluid extract ofwheat bran and that -tocopherol has been described in wheat bran oily extracts. Other commonquality parameters, directly correlated with oxidative degradation, were also evaluated. Acidityvalues around 15% oleic acid were detected, while low levels of hydroperoxides (around 2.4 meqO2/kg) and very low levels of hexanal (0.21 ppb) were found. Composition of the wheat bran oilyextract was stable during 155 days of storage at 21  C and darkness, and only a slight decrease inalkylresorcinols and tocopherols contents (13% and 20%, respectively) was observed. These resultsindicated an attractive potential of the obtained oily extract for industrial applications as foodingredients, nutraceuticals, and others.
