Essential oils (EOs) are commonly used in food industry, due that they possess antioxidative and antimicrobial properties. There are few essential oils that have been used in medicine, due to its potent antibacterial activity against intrahospital pathogens. OEO has experimentally shown potent antibacterial effect on nosocomial Gram-positive bacteria, therefore it can be very useful in hospital environments, where there are many bacterial pathogens, which are the etiological agents of nosocomial infections and most of them are resistant to several antibiotics. Objective: The aim of this study was to determine antimicrobial effect of OEO on most frequent bacterial intrahospital pathogens: MRSA, MRSE comparatively to selected ATCC bacterial reference strains. Methods: This experimental study investigates the antibacterial action of oregano (Origanum vulgare) essential oil (OvEO) on two human pathogens: Staphylococcus aureus (SA) and Staphylococcus epidermidis (SE) Here, we used OEO against one of the most prominent antibiotic-resistant bacterial strains: methicillin-resistant SA (MRSAmecA+ = Meticillin Resistant SA and mecA- = Meticillin Resistance SA ), methicillin-resistant SE (MRSEmecA+ = Meticillin Resistance Staphylococcus epidermidis mecA+) and reference strains: S. aureus ATCC 700699, S. epidermidis ATCC 359845 and E. coli ATCC 25922. Bactericidal effects of the OEO on these bacteria were mainly evaluated using undiluted and four serial dilutions in coconut oil (CCO) l: 1:10, 1:100, 1:200, 1:400. Results: OEO, undiluted and 4 serial dilutions showed potent antibacterial activity against all strains tested. In conclusion, this OEO could be used as an alternative in medicine. The ability of OEO to inhibit and kill clinical Multi-Drug-Resistant (MDR): MRSA and MRSE strains, highlights it´s potential for use in the management of drug-resistant MDR infections in hospitals wards.

ABSTRACT Since drug-resistant nematodes became a common problem in sheep and goat industries, alternative methods using natural products have emerged as a viable and sustainable anthelmintic treatment option. Here, the in vitro effect of essential oil extracted from Lippia gracilis Schauer was assessed on the hatching process of nematodes recovered from naturally infected goats. Essential oil at concentrations of 0.08% (0.008 μL/mL), 0.12% (0.012 μL/mL), and 0.16% (0.016 μL/mL) was able to induce an average inhibition of 74.7, 84 and 93%, respectively. The effective concentration required to inhibit egg hatching in 50% of eggs (EC50) was 0.03452%. Therefore, essential oil of L. gracilis showed promisor in vitro anthelmintic results against egg-hatching of goat gastrointestinal nematodes.

Objectives. The present work investigates the effect of essential oil from the twigs of Abies koreana on electroencephalographic (EEG) activity of human brain in order to understand the influence of binasal and uninasal inhalations. Methods. To accomplish this study, the essential oil from the twigs of A. koreana (AEO) was isolated by steam distillation and the EEG readings were recorded using QEEG-8 system from 8 grounding electrodes according to the International 10-20 System. Results. D-Limonene (25.29%), bornyl acetate (19.31%), camphene (12.48%), α-pinene (11.88%), β-pinene (6.45%), and eudesm-7(11)-en-ol (5.38%) were the major components in the essential oil. In the EEG study, the absolute alpha (left frontal and right parietal) and absolute fast alpha (right parietal) values significantly increased during the binasal inhalation of AEO. In the uninasal inhalation, absolute beta and theta values decreased significantly, especially in the right frontal and left and right parietal regions. The results revealed that the AEO produced different EEG power spectrum changes according to the nostril difference. Conclusion. The changes in EEG values due to the inhalation of AEO may contribute to the enhancement of relaxation (binasal inhalation) and alertness/attention (right uninasal inhalation) states of brain which could be used in aromatherapy treatments.

Background: Microbial resistance to antibiotics and their adverse effects related to these antibiotics are a matter of global public health in the 21th century. The emergence of drug-resistant strains, has gained the interest of the scientists to discover new antimicrobial agents from the essential oil of medicinal plants. Methods: Anti-mycobacterial effects of Trachyspermum copticum and Pelargonium graveolens essential oils were determined against multi-drug resistant clinical strains of Mycobacterium tuberculosis, Mycobacterium kansasii, Mycobacterium fortuitum and standard strain of Mycobacterium tuberculosis H37Rv by a Broth micro-dilution method. Pelargonium graveolens plant named Narmada was discovered by Kulkarni R.N et al. (Patent ID, USPP12425P2) and a formulation comprising thymol obtained from Trachyspermum is useful in the treatment of drug-resistant bacterial infections (Patent ID, US6824795B2). The chemical composition of hydro-distilled essential oils was determined by GC and GC-MS. Results: Minimum Inhibitory Concentration (MIC) values for T. copticum essential oil against tested isolates were ranged from 19.5 µg/mL to 78 µg/mL. The least minimum inhibitory concentration of P. graveolens extract against M. Kansasii and MDR-TB was 78 µg/ml. Conclusion: The results of the present research introduced T. copticum and P. graveolens essential oils as a remarkable natural anti-mycobacterial agent, but more pharmacological studies are required to evaluate their efficacy in animal models.

<p><strong>Objective: </strong>In the present study, the influence of harvesting time (April, June, August and October 2015) on the essential oil composition of <em>Abies koreana</em> twigs from Korea was investigated.</p><p><strong>Methods: </strong>The essential oil from the twigs of <em>A. koreana</em> was isolated by steam distillation and its chemical composition was determined by gas chromatography-mass spectrometry (GC-MS).</p><p><strong>Results: </strong>The essential oil yield was found to vary from 0.76 to 1.20% depending on the month of harvesting. The GC-MS analysis revealed the identification of 26 different essential oil components from the twigs harvested in the months of April, June, August and October, which were mostly monoterpene hydrocarbons (57.63–72.38%) followed by oxygenated monoterpenes (18.82–25.96%).<strong> </strong>Harvesting time mainly influenced on the concentration of the major components of the essential oil from the twigs of <em>A. koreana</em>. Limonene (17.38–31.13%), bornyl acetate (13.22–21.17%), camphene (12.56–13.26%), α-pinene (11.05–13.02%), β-pinene (4.55–5.70%), 3-carene (5.21–6.43%) and β-eudesmol (1.49–8.24%) were detected as the major components in the essential oil.</p><p><strong>Conclusion: </strong>The main differences between the essential oil compositions of four different months can be referred to limonene and bornyl acetate. The results showed considerable variations in the composition of essential oil, particularly quantitative variation during different harvesting months.</p>

Cinnamon Essential Oil

Abstract Introduction:Cinnamon is dietary part of almost every Indian, hence there is no harm to consume it or apply it as antibacterial agent. Herein, we have observed that 0.5, 0.6 and 0.7 % concentrations cinnamon essential oil sufficient to control A. hydrophila within 5hrs of exposure. Cinnamaldehyde of is major component of used essential oil which has targeted the Flgn, Fij and Flja protein of flagella flowed by inhibition of swimming motility. Cinnamaldehyde was associated with damaging of cell membrane and leakage of electrolytes in extracellular environment.Aim of the study:In the current study cinnamon essential oil has been used to control the growth of multiple drug resistant A. hydrophila. A. hydrophila was isolated from well water system, and it was imipenem resistant bacteria as well. Materials and Methods: Cinnamon essential oil was characterized by using HPLC and FTIR. Antibacterial killing mechanism was determined by using electrical conductivity test, cytotoxic test by MTT assay, cell wall integrity test and motility test. Results:Cinnamon essential oil has potential to control the growth of A. hydrophila, and complete inhibition of cells was observed within 5hrs of exposure to 0.7% concentration of essential oil. By motility test and molecular docking it has been confirmed that for killing of bacterial cells, cinnamaldehyde of cinnamon essential oil targeting the cell membrane proteins as well as flagellar proteins Flgn, Fij and Flja.
