Aim of the present study was the investigation of the chemical composition of Barbarea vulgaris W.T.Aiton volatiles. The plant material was collected in Akmolinskaya and Karagandinskaya provinces of Kazakhstan in 2009. Different plant parts (flower, leaf and herb) were subjected to microdistillation to obtain the volatiles. The volatiles were then analyzed by GC-FID and GC/MS methods.

The most of samples were rich in sulfur containing compounds. Methyl (methylthio) methyl disulfide (14.5%), dimethyl trisulfide (11.2%), dimethyl sulfide (3.4%) were detected in the herb of B. vulgaris from Akmolinskaya province. Chemical composition of the flower and leaf volatiles was found to show some differences. Isopropyl isothiocyanate (36.7%) was the main constituent in flower, while phytol (25.7%), hexadecanoic acid (9.3%), hexahydrofarnesyl acetone (7.4%), dodecanoic acid (5.5%) and isopropyl isothiocyanate (5.3%) were detected in the leaf. It should be noted that another sample of B. vulgaris from Akmolinskaya province was found to be very different in volatile composition. Namely, borneol (20.3%), camphene (13.5%), bornyl acetate (8.0%) and germacrene D (5.4%) were the major constituents.

In the flower and leaf of B. vulgaris from Karagandinskaya province, methallyl cyanide (50.5% and 12.9%), 3-butenyl isothiocyanate (15.6% and 43.8%) and isohexyl cyanide (4.2% and 0.9%) were the major volatile compounds.

To the best of our knowledge, the volatiles of B. vulgaris from Kazakhstan were not investigated previously.
