Rapeseed and rapeseed meals - Determination of glucosinolates content - Method using high-performance liquid chromatography (ISO 9167:2019)
This document specifies a method for the determination of the individual glucosinolates content in rapeseeds and rapeseed meals using high-performance liquid chromatography with gradient elution.
This method was tested on rapeseeds and rapeseed meals (Brassica rapa, Brassica napus and Brassica juncea) but is applicable to other plant materials, on the condition that the occurring glucosinolates previously identified are described in this document. On the contrary, the quantitative analysis of the concerned glucosinolate(s) is not carried out.
NOTE This method does not determine glucosinolates that are substituted on the glucose molecule, but these compounds are of little importance in commercial rapeseed and rapeseed meal.
Annex A presents the results of the interlaboratory trials for the gradient elution HPLC method. Annex B presents how to check the titre of the prepared internal standard solution. Annex C presents how to prepare and test the purified sulfatase solution and how to check the desulphation step on the ion exchange column. Annex D presents the HPLC and column performance criteria qualification.
The analysis of glucosinolates content in rapeseed can also be done using an isocratic elution mode. This requires some modifications of the method (internal, standard, HPLC column and HPLC buffers), as described in Annex E.
Rapssamen und Rapsschrot - Bestimmung des Glucosinolatgehaltes - Verfahren mittels Hochleistungsflüssigchromatographie (ISO 9167:2019)
Dieses Dokument legt ein Verfahren zur Bestimmung der einzelnen Glucosinolate in Rapssamen und Rapsschrot mittels Hochleistungsflüssigkeitschromatographie mit Gradientenelution fest.
Dieses Verfahren wurde an Rapssamen und Rapsschrot (Brassica rapa, Brassica napus und Brassica juncea) geprüft, ist jedoch auf andere Pflanzenmaterialien unter der Bedingung anwendbar, dass die vorkommenden Glucosinolate zuvor identifiziert wurden und in diesem Dokument beschrieben sind. Die quantitative Bestimmung des (der) betreffenden Glucosinolats (Glucosinolate) wird nicht durchgeführt.
ANMERKUNG Glucosinolate, die am Glucosemolekül substituiert sind, werden mit diesem Verfahren nicht erfasst, sind für handelsübliche Rapssamen und Rapsschrot jedoch auch von untergeordneter Bedeutung.
Anhang A enthält die Ergebnisse der Ringversuche für das HPLC Verfahren mit Gradientenelution. Anhang B stellt dar, wie der Titer der hergestellten internen Standardlösung überprüft wird. Anhang C stellt dar, wie die gereinigte Sulfatase Lösung hergestellt und geprüft wird und wie der Desulfatierungsschritt an der Ionenaustauschersäule überprüft wird. Anhang D stellt die Qualifikation der HPLC- und Säulenleistungs¬kriterien dar.
Die Analyse des Glucosinolatgehalts in Rapssamen kann auch unter Anwendung eines isokratischen Elutionsmodus erfolgen. Das erfordert einige Modifikationen des Verfahrens (interner Standard, HPLC Säule und HPLC Pufferlösungen), wie in Anhang E beschrieben.
Graines et tourteaux de colza - Dosage des glucosinolates - Méthode par chromatographie liquide à haute performance (ISO 9167:2019)
Le présent document spécifie une méthode de dosage des glucosinolates individuels dans les graines et tourteaux de colza par chromatographie en phase liquide à haute performance avec élution par gradient.
Cette méthode a été soumise à essai sur les graines et tourteaux de colza (Brassica rapa, Brassica napus et Brassica juncea), mais elle est applicable à d'autres matériaux végétaux, à condition que les glucosinolates identifiés précédemment soient décrits dans le présent document. Sinon, l'analyse quantitative du ou des glucosinolates concernés n'est pas effectuée.
NOTE Cette méthode ne dose pas les glucosinolates ayant des substituants sur la partie glucose, mais ces composés sont peu importants dans les graines et tourteaux de colza commercialisés.
L'Annexe A présente les résultats des essais interlaboratoires pour la méthode de CLHP avec élution par gradient. L'Annexe B présente comment vérifier le titre de la solution préparée d'étalon interne. L'Annexe C présente comment préparer et analyser la solution purifiée de sulfatase et contrôler l'étape de désulfatation sur la colonne échangeuse d'ions. L'Annexe D présente la qualification du système de CLHP et des critères de performance de la colonne.
Les glucosinolates des graines de colza peuvent également être dosés en utilisant un mode d'élution isocratique. Cela nécessite un certain nombre de modifications de la méthode (étalon interne, colonne de CLHP et solutions tampons pour CLHP), comme décrit dans l'Annexe E.
Seme in obroki oljne repice - Določevanje glukozinolatov - Metoda s tekočinsko kromatografijo visoke ločljivosti (ISO 9167:2019)
Ta dokument določa metodo za določevanje vsebnosti posameznih glukozinolatov v semenu in obrokih oljne repice s pomočjo tekočinske kromatografije visoke ločljivosti z gradientnim eluiranjem. Ta metoda je bila preskušena na semenu in obrokih oljne repice (Brassica rapa, Brassica napus in Brassica juncea), vendar se uporablja tudi za druge rastlinske materiale pod pogojem, da so v tem dokumentu opisani obstoječi glukozinolati, ki so bili predhodno prepoznani. Nasprotno se ne opravi kvantitativna analiza zadevnega glukozinolata oziroma glukozinolatov.
OPOMBA: Ta metoda ne določa glukozinolatov, ki so v molekuli glukoze nadomeščeni, vendar te spojine v okviru obroka komercialne oljne repice in oljne repice nimajo velikega pomena. V dodatku A so predstavljeni rezultati medlaboratorijskih preskusov za gradientno eluiranje po metodi HPLC. V dodatku B je predstavljeno, kako je mogoče preveriti porabo pripravljene raztopine iz internega standarda. V dodatku C je predstavljeno, kako pripraviti in preskusiti prečiščeno raztopino sulfataze ter kako preveriti korak desulfatizacije v koloni za ionsko izmenjavo. V dodatku D sta predstavljeni metoda HPLC in uvrstitev merila uspešnosti kolone. Analiza vsebnosti glukozinolatov v oljni repici je mogoča tudi z načinom izokratskega eluiranja. Za to je potrebnih nekaj prilagoditev metode (notranje, standardne, kolona HPLC in puferske raztopine za HPLC), kot je opisano v dodatku E.
