Abstract: 【Objective】The variation principal in different growth periods of glucosinolates content was studied, and glucosinolate content correlations between Brassica napus leaves and seeds were discussed.【Method】Glucosinolates content and components were analyzed by high performance liquid chromatography (HPLC). 【Result】Leaf glucosinolate content in double-high material Zhongyou821 decreased from rosette to blooming stage, while in double-low material leaf glucosinolate increased from overwintering to budding period, decreased at stem elongation stage and rose again at early blooming stage. Leaf glucosinolate contents and profiles varied significantly in double-high and double-low rapeseeds. However, it was very close to each other in stem elongation period, and aliphatic glucosinolates were the dominant ones in both leaves. 【Conclusion】There was no significant correlation in individual glucosinolate content between leaves and seeds in all double low rapeseed materials tested. Changes of glucosinolate contents in leaves will not affect glucosinolate content in seeds significantly.
