Contrastive analysis of chemical composition of essential oil from twelve, The cytotoxic effect and the antiviral activity varied significantly within Eucalyptus species oils. Essential oil can be broken down into an array of different natural chemical constituents. 2017 Mar 28;27(3):429-438. doi: 10.4014/jmb.1608.08024. Virus pretreatment with E. bicostata essential oil showed better antiviral activity (IC(50) = 0.7 mg/ml, SI = 22.8) than cell-pretreatment (IC(50) = 4.8 mg/ml, SI = 3.33).

Chemical analysis was carried out through GC-EIMS, 13C NMR and Kovats Retention Indices while pharmacological study was carried out in isolated tissues preparations.

In addition, the bactericidal, fungicidal and the antiviral activities of the tested oils were carried out. It discusses the usage of essential oil constituents as a key marker of the oil … This chapter focuses on the heterogeneous composition of the essential oils. The essential oils of eight Eucalyptus species harvested from the Jbel Abderrahman, Korbous (North East Tunisia) and Souinet arboreta (North of Tunisia) were evaluated for their antimicrobial activities by disc diffusion and microbroth dilution methods against seven bacterial isolates: Haemophilus influenzae, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus pneumoniae and Streptococcus pyogenes. These data indicate that Nepeta cataria possesses spasmolytic and myorelaxant activities mediated possibly through dual inhibition of calcium channels and PDE, which may explain its traditional use in colic, diarrhea, cough and asthma.

In Tunisia, our previous works conducted in 2010 and 2011 had been the first reports to study the antibacterial activities against reference strains. The antioxidant activity of essential oil from Curcuma attenuata Wall (IC50, 3.69 μg/ml) was superior to all other oils. -. doi: 10.1007/s00284-007-9045-0.

2008;56:89–92. The study was aimed to investigate the chemical composition and pharmacological basis for traditional use of essential oil of Nepeta cataria L. (Limiaceae) (Nc.Oil) in gastrointestinal and respiratory disorders. 2002;17:1–14. Shop for carrier oils… By continuing you agree to the use of cookies. Agence de Coopération Culturelle et Technique. The yields of the 12 essential oils ranged from 2.23 wt.% in Curcuma yunnanensis to 4.50 wt.% in Curcuma longa. The compositions and antioxidant activities of essential oils of 12 Curcuma species distributed in China were studied. These components were used to correlate with the biological activities of the tested oils. Abu-Jafar A, Suleiman M, Nesim N, Huleihel M. Cell Cycle. This site needs JavaScript to work properly. Chemical composition of essential oil Essential oils (EOs) are volatile constituents obtained from aromatic plant material, including leaves, rhizomes, flowers, roots, bark, seeds, peel, fruits, wood and … 2012 Mar 12;17(3):3044-57. doi: 10.3390/molecules17033044. Bloomings Book. Essential oil from Nepeta cataria L. grown in Pakistan has not been explored yet for its chemical composition or its biological effects related to medicinal use in hyperactivity of gut and airways disorders. Field guide to Eucalyptus (2nd ed. Methods: 2010 Apr;7(4):909-21. doi: 10.1002/cbdv.200900229. Melbourne, Northern Australia; 2004. Microb Pathog. In isolated guinea-pig atria, Nc.Oil caused cardiodepression at around 25–80 times higher concentrations, similar to papaverine. Phytother Res. However, the best antiviral activity appeared with E. bicostata. HHS 2020 Jul;19(14):1768-1776. doi: 10.1080/15384101.2020.1779455. Eucalyptus (gracilis, oleosa, salubris, and salmonophloia) essential oils: their chemical composition and antioxidant and antimicrobial activities. The chemical principal component analysis identified three groups, each of them constituted a chemotype. In addition, E. odorata oil showed the most cytotoxic effect.

Antimicrobial Activity of Basil, Oregano, and Thyme Essential Oils. We use cookies to help provide and enhance our service and tailor content and ads. At that time it was not possible to evaluate their antimicrobial activities against clinical bacterial strains and other pathogens such as virus and fungi. This activity was dose-dependent and the antiviral activity diminished with the decreasing essential oil concentration.
