Scope: What is ISO 9167- Determination of glucosinolates content in rapeseed and rapeseed meals about? ISO 9167 discusses rapeseed and rapeseed meals. ISO 9167 is an international standard on the determination of glucosinolates content in rapeseed and rapeseed meals using high-performance liquid chromatography to ensure the prevention of various health hazards. ISO 9167 specifies a method for the determination of the individual glucosinolates content in rapeseed and rapeseed meals using high-performance liquid chromatography with gradient elution. ISO 9167 specifies a method using high-performance liquid chromatography (HPLC) with gradient elution as a reference method. For the isocratic mode, the choice of the internal standard, the chromatographic conditions, and the separation results are different from the reference method. The method under ISO 9167 was tested on rapeseed and rapeseed meals (Brassica rapa, Brassica napus, and Brassica juncea) but applies to other plant materials, on the condition that the occurring glucosinolates previously identified are described in ISO 9167. Note: The method specified under ISO 9167 does not determine glucosinolates that are substituted on the glucose molecule, but these compounds are of little importance in commercial rapeseed and rapeseed meal. ...
