Chromatographic profiles and antimicrobial activity of the essential oils obtained from some species and cultivars of the tribe (.

The present study was focused on the chemical composition and antimicrobial activity of the essential oils (EsO) obtained from five representatives grown in the south of Ukraine. Among them are L. (cultivar 'Cambridge Scarlet'), (cultivar '2/6-07') (cultivar 'Jalos') and L. The component analysis of the EsO was carried out by gas chromatography method coupled with mass spectrometry (GC-MS). The antimicrobial properties of the EsO were determined using the agar diffusion test against widespread pathogenic bacterial strains () and opportunistic yeast The EsO of and (cultivar 'Jalos') displayed noteworthy antibacterial properties against a wide spectrum of the microorganisms. These antimicrobial properties could be attributed to the high content of aromatic monoterpenoid thymol (52.56% and 47.33%, respectively). The EsO of with the dominance of linalyl acetate (45.51%) and linalool (38.98%) as well as (cultivar '2/6-07') containing citral (27.10%) and -citral (17.11%) demonstrated the strongest antimicrobial effects on typical and clinical strains of with the inhibition zones in the range of 24.0-31.0 mm. The EsO demonstrated the most significant effect against clinical strains of . In conclusion, the present study revealed the chemical composition of five species and cultivars grown in the south of Ukraine and considerable antimicrobial activity of the tested EsO, especially against the typical and clinical strains of and . The obtained results could be perspective for applying in the pharmaceutical industry and for the conservation of food and cosmetic products.
