Sažetak
Volatile sulfur compounds and heavy metals were investigated in different parts of the two plants: kohlrabi (Brassica rupestris Raf. ssp. gongyloides (L.) Janch. ; Brassicaceae family) and leek (Allium porrum L. ; Amaryllidaceae family). Owing to the presence of sulphur, volatile sulphur compounds show particular physicochemical features and interact with a range of molecular and biological targets. The main volatiles in B. rupestris were found to be degradation products of glucosinolates: sinigrin (allyl isothiocyanate), glucotropaeolin (benzeneacetonitrile and benzyl isothiocyanate), gluconasturtiin (2-phenylethyl isothiocyanate), and glucoreucin (4-(methylsulfanyl)butyl isothiocyanate), as well as from degradation of S-methylcysteine sulfoxide commonly named methiin (dimethyl trisulfide and dimethyl tetrasulfide). The main volatiles in A. porrum were derived from S-cysteine sulfoxide degradation: methiin, propiin, and isoaliin (methyl propyl trisulfide, (E)-propenyl propyl trisulfide, dipropyl disulfide, (E)-propenyl propyl disulfide, dimethyl trisulfide, dipropyl trisulfide). Concentrations of various heavy metals have also been determined. The concentrations of heavy metals determined were in sequence Al > Fe > Mn > Zn > Cu > Ni > Pb > Mo > As > Co > Cd > Se for kohlrabi and Al > Fe > Mn > Zn > Cu > Ni > Mo > Pb > Co > Cd > As, Se for leek, respectively.
