The chemical composition of the essential oils obtained from two samples (GP1 and GP2) of Grammosciadium platycarpum Boiss. was analyzed by GC and GC-MS. The analysis of the oils resulted in the identification of twenty-two constituents. Linalool (79.0% - GP1, 81.8% - GP2) and limonene (10.0%, 5.8%) were found to be the major components, respectively. The in vitro antibacterial activities of these oils and their main compounds against seven Gram-positive and Gram-negative bacteria were investigated. The results exhibited that the total oils and their major components possess strong to moderate activities against all the tested bacteria except for Pseudomonas aeruginosa.

In this study, we aimed to determine chemical composition and antibacterial activities of Satureja hortensis and Calamintha nepeta against to 20 phytopathogenic bacteria causing serious crop loss. The essential oils of S. hortensis and C. nepeta were isolated by the hydrodistillation method and the chemical composition of the essential oils were analyzed by GC-MS. The antibacterial properties of the essential oils were evaluated against 20 phytopathogenic bacteria through Disc diffusion assay and micro dilution assay. The results revealed that the essential oils of S. hortensis and C. nepeta have significant antibacterial activity. Furthermore, the findings of the study are valuable for future investigations focusing on the alternative natural compounds to control plant diseases.

Abstract. Benachour H, Ramdani M, Lograda T, Chalard P, Figueredo J. 2020. Chemical composition and antibacterial activities of Capparis spinosa essential oils from Algeria. Biodiversitas 21: 161-169. The essential oils of Capparis spinosa L. collected from six locations in Algeria were obtained by hydro-distillation. The chemical composition of oils was performed by GC-MS. The disc diffusion method is applied for the antibacterial activity. The extraction produced low yield (0.03%). The result of chromatographic analysis (GC/MS) leads to the identification of 33 components; palmitic acid (38.19%), nonanal-n (12.61%), cymene-2,5-dimethoxy-para (8.94%) and octacosane (5.49%) were the major components of these oils. The result of cluster analysis based on essential oils constituents showed the presence of three chemotypes,i.e., the chemotype of Nonanal-n-Cymen 2,5 dimethoxy para-Dodecanal, the chemotype of Nonanal-n-Hexadecanoic acid-tetracosane and the chemotype Tetracosane-n-pentyl furane-2-octacosane. In-vitro antimicrobial activity of caper oils against nine bacterial species showed that the oils have no activity against E. coli and have modest activities against eight other bacterial species tested; however, the desirability test shows that the oils used were not effective on the bacteria tested.

Chemical composition of fifteen samples of juniper essential oil was analyzed using GC/FID/MS method. Thirteen samples of berries were collected on different locations in south-western part , two of them in central-north region of Republic of Macedonia. The essential oils were obtained by hydrodistillation in a Clevenger type apparatus using official method of European Pharmacopoeia. GC/MS analysis revealed 74 identified components. The predominant fractions of the oils were monoterpene hydrocarbons representing 39.11- 73.38%. Great variability in the chemical composition and content of some components was observed. The most variable components were α-pinene (15.59-43.19%), β-pinene (1.65%-5.35%), β-myrcene (2.89%-26.50%), sabinene (2.80-11.77%), and limonene (2.90-4.46%). In the fraction of oxidized monoterpenes the most abundant was terpene-4-ol (trace - 6.32%) followed by α-terpineol (0.18-1.63%). In the sesquiterpene fraction predominant components were: germacrene D (2.76-10.22%), β-elemene (1.13-3.40%) and trans-(E)-caryophyllene (1.8%- 4.05%). Twelve samples of Macedonian juniper oils comply with European Pharmacopoeia chemical composition requirements for juniper oil and three samples did not, due to lower amount of α-pinene.
