Two wild-growing Brassicaceae plants of Croatian origin, Aurinia leucadea (Guss.) K. Koch and Lepidium draba L., were investigated to uncover glucosinolates via GC/MS analysis of their degradation products. The main constituents of Aurinia leucadea (Guss.) K.Koch distillate were hex-5-enenitrile (28.8%) and but-3-enyl isothiocyanate (18.8%), while 4,5-epithiopentanenitrile (50%) and 5,6-epithiohexanenitrile (18.5%) were the main volatile compounds in autolysate. 4-(Methylsulfanyl)butyl isothiocyanate (96.4%) constituted almost the entire Lepidium draba L. distillate, while the autolysate was characterized by 4-(methylsulfinyl)butyl isothiocyanate (57.3%). So, regarding the glucosinolate degradation products, the main glucosinolates of A. leucadea were glucobrassicanapin and gluconapin, and of L. draba glucoerucin and glucoraphanin.
