Background: The essential oil from the Acantholimon genus have been an integral part of the traditional food additive in Middle East. Most of the plants in Acantholimon genus have not been studied scientifically. The aim of this study is to investigate the chemical composition, antibacterial, insecticidal and anti-oxidant activities of three Acantholimon species including Acantholimon atropatanum, A. gilliatii and A. tragacanthium. Method: The essential oils of the aerial parts were extracted by hydrodistillation. Chemical constitutions were identified by gas chromatography- mass spectroscopy technique, also their toxicities were assessed against the two important grain products pests, Oryzeaphilus mercator and Tribolium castaneum. Antibacterial activity was assessed against the three foodborne bacteria that include Escherichia coli, Pseudomonas aeruginosa and Staphylococcus aureus based on the disc diffusion assay. Free-radical-scavenging property was identified based on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Results: 2-hexahydrofarnesyl acetone was the main compound in A. gilliatii and A. tragacanthium, whilst farnesyl acetone, heptacosane and germacrene D were the principal components of A. atropatanum essential oil. These oils exhibited 40-90% mortality of O. mercator and/or T. castaneum at a dose of 12 μl/l air after 48h of exposure, and exhibited significant free-radicalscavenging property (RC50 = 3.7 × 10-3 - 8.3 × 10-3 mg/ml). The oils of A. tragacanthium and A. gilliatii showed a weaker antibacterial activity compared to A. atropatanum. Conclusion: A. atropatanum, A. gilliatii and A. tragacanthium essential oils had significant insecticidal and anti-oxidant properties. They also showed week to moderate antibacterial activity against P. aeruginosa and S. aureus.

Essential oils constitute a heterogeneous collection of chemical compounds. Their main characteristics are that they all synthesized by plants and are volatile and mostly soluble in ethanol. They have traditionally been obtained from plants and they have been widely used for insecticidal, medicinal and cosmetic purposes. Essential oils contains about 20–60 components at quite different concentrations and they are characterized by two or three major components at fairly high concentrations. Lately, the essential oils and various extracts of plants have gained special interest as sources of natural antimicrobial and antioxidant agents because of the resistance to antibiotics that some microorganisms have acquired and the possible toxicities of the synthetic antioxidants. Spices consumed daily in different types of food to improve flavors, since ancient times, are well known for their antioxidant and antimicrobial properties. During recent decades, numerous numbers of plants have been monitored for their possible role as repellents and insecticides. In this review, the chemical composition profile of some important medicinal plants was evaluated, then antimicrobial properties of a number of essential oils was compared. Antioxidant activity of some essential oils was also considered. Finally, essential oil repellent properties an an important characteristics was evaluated. Further investigation for available data related to the other biological properties of medicinal plants essential oil is recommended.DOI: http://dx.doi.org/10.3126/ijls.v9i2.12043 International Journal of Life Sciences 9 (2) : 2015; 9-13

The chemical composition of the essential oils of aerial parts of Artemisia campestris ssp. campestris, collected from ten different locations in Lithuania is detailed in this paper. The major component in all the oils was caryophyllene oxide (8.5-38.8%), whereas compounds with the caryophyllane skeleton ranged from 10.2 to 44.5%. Other representative constituents were germacrene D (≤15.0%), humulene epoxide II (≤8.1%), β-ylangene (≤7.7%), spathulenol (≤6.8%), β-elemene (≤6.8%), β-caryophyllene (≤6.2%), junenol (≤6.1%) and α- or β-pinene (≤5.5%). Eighty-seven compounds were identified, comprising 73.6-92.3% of the oils. The chemical composition was highly variable depending on the sample location. Toxicity of A. campestris oils was determined using the brine shrimp (Artemia sp.) assay. LC50 values ranging to 20 μg/mL were obtained for three of the oils after 24 hours of exposure. Data of this test revealed that A. campestris ssp. campestris essential oils with dominant caryophyllene oxide are notably toxic.

First Time

Air-dried aerial parts of wild Cladanthus mixtus were collected from two different regions of Morocco, Bouznika and Oujda, during 2011 and 2012. Forty individual plant samples were hydrodistilled using a Clevenger apparatus and the obtained essential oils were analyzed by GC and GC/MS. The yield obtained varies greatly with a range of 0.3 to 0.8%. The chemical composition of C. mixtus oils changes from one region to another. A total of 53 constituents were identified. To the best of our knowledge, two chemotypes were defined for the first time for this species in the regions studied. 2-Methyl-2- trans-butenyl methacrylate (32.8–35.2%) / ar-curcumene (13–14%) characterize the chemotypeof the C. mixtus plants from Bouznika, and trans-β-farnesene (35.5–50.3%) the chemotype from Oujda.
