Summary The oil from weed seed screenings from Western Canadian grain was found to consist of 31% oleic, 27% linoleic, 13% linolenic, 12% eicosenoic, 8.4% erucic, 6.3% saturated, and small amounts and traces of other acids. Eicosenoic acid was found in greater abundance than erucic acid, a result probably related to the fatty acid composition of charlock. The presence of eicosadienoic, eicosatrienoic, and docosatrienoic acids, hitherto unreported in vegetable oils, is strongly suggested.
