Citación: | Pure and Applied Chemistry 71(2): 349-359 (1999) | Resumen: | The development by collaborative study of a standardised method for the deter-mination of the stigmastadienes content in vegetable oils is described. The procedureinvolves the isolation of the unsaponifiable matter in the oil ands its fractioning on a silicagel column. The fraction containing the steroidal hydrocarbons is then analysed by capillarygas chromatography and the quantitative assessment made by the use of an internal standard/cholestan-3,5-stadiene. The procedure is very sensitive allowing determination at levels of0.01–4.0 mg/kg. | Versión del editor: | http://dx.doi.org/10.1351/pac199971020349 | URI: | http://hdl.handle.net/10261/282626 | DOI: | 10.1351/pac199971020349 | Identificadores: | doi: 10.1351/pac199971020349 issn: 0033-4545 e-issn: 1365-3075 |
