[en] Total glucosinolate content in rapeseeds cultivated in France. Germany. Denmark, United Kingdom and Belgium has been determined by high performance liquid chromatography (HPLC), gas liquid chromatography (GLC),measurement of glucose released by myrosinase and Pd glucosinolate complex after purification on an ion exchange column. Methods are well correlated. Glucose method and HPLC give similar results r: O.995, bias: O.055 µM/gr). ln most cases. GLC results are lower than HPLC (r: O.995, bias: - 2.482 µM/gr). Palladium method gives systematically higher results than HPLC (t: 0.99O, bias: 6.763 µM/gr).
