An in-depth glucosinolate (GLS) profiling was performed on a core collection of 91 Brassica rapa accessions, representing diverse morphotypes heterogeneous geographical origin, to better understand the natural variation in GLS accumulation and breakdown product formation. Leaves B. accessions were analyzed for their composition by UHPLC-DAD corresponding products GC-MS. Fifteen different GLSs identified, aliphatic prevailed regarding diversity concentration. Twenty-three among them nine isothiocyanates, ten nitriles, four epithionitriles. Epithionitriles prevailing due high abundance alkenyl GLSs. The large scale data set allowed identification correlations specific or products. Discriminant function analysis identified subspecies with levels similarity acquired metabolite profiles. In general, five main grouped significantly terms
