The present study was carried out to determine, for the first time, the chemical composition and antibacterial activity of essential oils derived from the aerial parts of three aromatic plants Thymus algeriensis Boiss & Reut, Rosmarinus officinalis L., and Salvia officinalis L. growing under semiarid conditions. The essential oils were chemically analyzed and identified by gas chromatography (GC) and GC/ mass spectrometry (GC/MS) and their antimicrobial activity was individually evaluated against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa using both agar disk diffusion and agar dilution methods. The major constituents of Thymus algeriensis essential oil were identified as camphor (13.62%), 1,8-cineol (6.00%), borneol (5.74%), viridiflorol (4.00%), and linalool (3.93%). For Rosmarinus officinalis essential oil, 48 compounds were characterized, of which the main constituents were camphor (17.09%), Z-β-ocimene (10.88%), isoborneol (9.68%), α-bisabolol (7.89%), and borneol (5.11%). While, Salvia officinalis essential oil was characterized by β-thujone (16.44%), followed by viridiflorol (10.93%), camphor (8.99%), 1,8-cineol (8.11%), trans-caryophyllene (5.85%), and α-humulene (4.69%) as the major components. Notably, results from antibacterial screening indicated that Thymus algeriensis and Salvia officinalis essential oils exhibited a strong inhibitory effect against both Escherichia coli and Staphylococcus aureus compared to Rosmarinus officinalis essential oil. Further, less activity was recorded against Pseudomonas aeruginosa for the three tested essential oils.

Main Components

The essential oil obtained by hydrodistillation method from plants of three varieties Agastache aurantiaca, cultivated on the Republic of Belarus were investigated. Some morphobiometric parameters of plants 'Tango', 'Apricot Sprite' and 'Fragrant Delight' and oil yields were determined. Using the technique of gas-liquid chromatography essential oil components were identified and determined. The main components of the essential oil from 'Tango' and 'Fragrant Delight' plants were menton (~ 53 and ~ 65 v/v % respectively) and pulegon (~ 36 and ~ 25 v/v % respectively). The samples of 'Apricot' Sprite' essential oil were rich in isomentone (~ 46 v/v %) and pulegon (~ 41 v/v %). All tested essential oils contained (+)-menton and (+)-pulegon enantiomeric forms only. The antibacterial activity of dimethylsulfoxide and ethanolic essential oil solutions against Staphylococcus aureus, Salmonella alony, Bacillus subtilis, Clostridium sp., Escherichia coli Hfr H, Pseudomonas aeruginosa was proved. Ethanol solutions of essential oils at the concentrations 0.001–0.1 v/v % had significant bactericidal activity. A correlation between the composition of the essential oil and their antibacterial properties was established.

Present study involves the study of the chemical composition of the essential oils extracted from the leaves by gas chromatography and gas chromatography coupled with mass spectrometry of Lippia multiflora harvested in the regions of Kétou, Savalou, Bohicon and Mono and tested by the well diffusion method against pathogenic microorganisms. The essential oils studied are terpene compounds, aromatic compounds, aliphatic compounds and other natural substances. The inhibition zone diameters determined allowed us to evaluate their degree of germ sensitivity of the strains tested. Essential oils extracted from Lippia multiflora harvested in these areas have the most pronounced antimicrobial activity. In total, the essential oils tested have different and specifically a degree of sensitivity against Staphylococcus aureus ATCC 25923, Escherichia coli ATCC 25922, Proteus mirabilis A24974, Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa except that harvested in the Savalou who does not have no degree of sensitivity on Pseudomonas aeruginosa. This work paves the way for food preservation with extracted natural substances and also the formulation of natural antimicrobials for this fact.

The aim of the present study was to determine the chemical composition of eight plant essential oils and evaluate their antibacterial activity against Escherichia coli strains isolated from different turkey organs. The essential oils were extracted by hydrodistillation and analyzed using gas chromatography-mass spectroscopy. All essential oil yielded high in a range between 2.2 and 3.12%. Gas chromatography-mass spectroscopy (GC-MS) revealed that the major constituents of Thymus vulgaris, Ocimum basilicum, Artemisia herba-alba, and Syzygium aromaticum oils were thymol (41.39%), linalool (37.16%), camphor (63.69%), and eugenol (80.83%), respectively. Results of the E. coli sensitivity evaluated by the standard antimicrobial sensitivity method varied depending on the organ of isolation. Similarly, the essential oils antimicrobial activity determined by the disc diffusion method varied all along within the organs of isolation. T. vulgaris essential oil showed the highest effective antibacterial activity against E. coli isolated from the throat with an inhibition zone diameter value of up to 23.33 mm. However, all the essential oils showed antibacterial activity and the MIC and MBC values were in the range of 1/3000 to 1/100 (v/v) and the ratios MBC/MIC were equal to 1. In conclusion, this study showed that the essential oils could be promising alternatives to overcome E. coli multiresistance in turkey.
