Antibacterial activities of essential oils and extracts of TurkishAchillea, SaturejaandThymusspecies against plant pathogenic bacteria

Plant essential oils of six aromatic herb species and interspecies hybrids of the family Lamiaceae – chocolate mint (Mentha piperita × ‘Chocolate’), pineapple mint (Mentha suaveolens ‘Variegata’), apple mint (Mentha × rotundifolia), spearmint (Mentha spicata), orange mint (Mentha × piperita ‘Granada’) and strawberry mint (Mentha × villosa ‘Strawberry’) – were investigated for antimicrobial effects against plant pathogenic bacteria: Agrobacterium tumefaciens, Pseudomonas syringae pv. syringae and Xanthomonas arboricola pv. corylina. The screening was carried out in vitro on agar plates filled with the target organism. All essential oils screened exhibited a higher level of antibacterial activity against A. tumefaciens and X. arboricola pv. corylina than streptomycin used as a standard in all tests. The antimicrobial effect of streptomycin and five mint oils was at the same level for P. syringae pv. syringae. There were no significant differences in the influence of the chocolate mint oil on the growth inhibition of all bacteria tested. Plant essential oils from pineapple mint, apple mint, spearmint and strawberry mint showed the weakest antimicrobial activity against P. syringae pv. syringae and the strongest towards A. tumefaciens and X. arboricola pv. corylina. The essential oils from strawberry mint, pineapple mint, spearmint and apple mint had the strongest effect on A. tumefaciens, and the lowest inhibitory activity was exhibited by the chocolate mint and orange mint essential oils. X. arboricola pv. corylina was the most sensitive to the strawberry mint, pineapple mint and spearmint oils. The chocolate mint oil showed the greatest activity against P. syringae pv. syringae.

Toxicological Studies

The present work aimed to study the composition and antibacterial properties of the essential oils (EO) of Ocotea zahamenensis leaves (LEO), stem (SEO) and root (REO) barks from two harvest periods (March and June). All EOs were extracted by hydrodistillation from fresh plant parts with yields up to 4.5%. They are colourless, clear, with a strong odour, heavy, levogyre, with a low acid index and an ester index up to 14.89. Gas chromatography/flame ionisation detection analysis of these EOs identified 5 to 12 components representing 96.06 to 99.96% of the overall composition. Safrole was by far the most predominant constituent with contents ranging from 77.45% (SEO, June) to 97.05% (REO, March). The antibacterial activity was tested against eight pathogenic bacteria including 4 Gram (-) and 4 Gram (+) using microdilution assays. With Minimum Inhibitory Concentration (MIC) values of less than 1 mg/mL, all EOs showed antibacterial activity which varied according to the strain. There was not much difference between the activities of March and June Eos, and in both cases SEO were slightly more effective than LEO and REO. All EOs had bacteriostatic action on Bacillus cereus and Vibrio fischeri and bactericidal on almost other strains. When administered orally to mice at 0.5 mg/kg body weight, all EOs caused symptoms of intoxication. Their LD50 varied from 1.019 to 2.73 g/kg body weight. These EOs could be a new source of safrole and could be used for various purposes with further toxicological studies.

The chemical composition was analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS). The constituents were identified by their mass spectra and Kovats’ indices. Fivety (50) components in the oil of M. vulgare were identified. The results demonstrated that the major components of the essential oil were: 4,8,12,16-Tetramethyl heptadecan-4-olid (16.97%), Germacrene D-4-ol (9.61%), α- pinéne (9.37%), Phytol (4.87%), Dehydro-sabina ketone (4.12%), Piperitone (3.27%), δ-Cadinene (3.13%), 1-Octen-3-ol (2.35%) and Benzaldehyde (2.31%). The antioxidant activity of the oils was assessed by measurement of metal chelating activity, the reductive potential, the free radical scavenging (DPPH) assay. The antioxidant activity was compared with that of synthetic antioxidants: butylated hydroxyanisole (BHT), and the essential oils. The results showed as the Essential oil of M. vulgare was evaluated for its antibacterial activities against Gram-positive and Gram negative pathogenic bacteria: Listeria monocytogene, Pseudomonas aeruginosa, Agrobacterium tumefaciens and Salmonella enterica.
