The chemical constituents of leaf and peel essential oil of Citrus medica L. were analysed by gas chromatography mass spectroscopy (GC-MS). Nineteen components accounting for 99.9% of the oil were identified in leaf oil. The major constituents are erucylamide (28.43%), limonene (18.36%) and citral (12.95%). The peel oil contains forty three components accounting for 99.8% of the total oil and the major components are isolimonene (39.37%), citral (23.12%) and limonene (21.78%).

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.

Introduction: White pepper is an important commodity used to produce essential oils. Differences in the oil components are determined by which region the peppers used were sourced from. Objectives: The aim of this study was to analyse the components of the essential oils produced by white peppers from different regions and to examine the specificity of these peppers. Methods: This analysis was carried out using the chromatography gas – mass spectroscopy (GC-MS) method on essential oil samples made from peppers obtained from the Java, Sumatera, Kalimantan, and Sulawesi Islands. Results: The results showed that white pepper essential oil contains 22 components, and that α-pinene, ꞵ–pinene, ∆-carene, sabinene, dl-limonene, and caryophyllene were major compounds within the oils. Furthermore, it showed that α-pinene, sabinene, and caryophyllene compounds were most found in samples from the Kalimantan, Sumatra, and Sulawesi Islands respectively. Meanwhile, those from Java Island contained ꞵ – pinene, ∆-carene, and caryophyllene in similar quantities.
