AbstractFoot odour (bromodosis) is an embarrassing and perplexing condition mostly caused by bacteria of the Brevibacterium species. Essential oils are a credible option as an affordable treatment of odour and contribute towards antimicrobial efficacy. Therefore, this study sets out to investigate the antimicrobial activity of essential oil combinations against odour-causing bacteria. The broth microdilution method was used to investigate the antimicrobial activity of 119 essential oil combinations, and the fractional inhibitory index was calculated to determine the interactive profile. Combinations that resulted in synergy in 1 : 1 ratios were further evaluated in different concentrations, and isobolograms were plotted to determine the influence of the ratio on overall activity. Numerous combinations could be identified as having synergistic interactions against the Brevibacterium spp. and no antagonism was observed. The combination of Juniperus virginiana (juniper) and Styrax benzoin (benzoin) demonstrated synergy against all three Brevibacterium spp. tested and J. virginiana was the essential oil responsible for the majority of the synergistic interactions. The results reported here confirm the promising potential of the majority of these oils and selected combinations in treating and controlling bromodosis.

Treatment Of Depression

: Depression is a mood disorder or affective disorder disease with depression as the main symptom. It has become a kind of mental disease that cannot be ignored in the world that seriously endangers human physical and mental health. Antidepressants commonly used in clinics generally have some defects including slow action, unremarkable effects and large side-effects. Therefore, there has a huge developing space for the research of new and effective therapeutic drugs to supplement or replace traditional drugs. Essential oil has obvious advantages in the treatment of depression and other emotional diseases, its aromatic odor can directly stimulate the olfactory nerves, and the lipophilic small- molecular compounds can cross the blood-brain barrier easily, to play its regulatory role of releasing of neurotransmitters and hormones related to depression, or adjusting the expression of brain-derived neurotrophic factor and proinflammatory cytokines. The pathogenesis of depression and the problems in traditional medication was illustrated, the research on the antidepressant effects and mechanism of essential oils in recent years was summarized and the antidepressant chemical components in plant essential oils were reviewed in this article. It could provide scientific basis for essential oil to be a new choice for relieving depression and treating depression.

The aim of the current research is to determine chemical constituents in the essential oil of P. graveolens by GC-MS and evaluate its antidiabetic activity via α-glucosidase inhibition assay. The chemical composition of P. graveolens essential oil was determined by GC/MS and its antidiabetic activity was assessed through inhibition of α-glucosidase enzyme in in-vitro models. GC-MS analysis determines 36 chemical components in the essential oil of P. graveolens leaves, and citronellyl isovalerate (10.41 %), menthol (9.61 %), linalool (8.63 %), p-menthone (6.31 %), and geranyl tiglate (4.99 %) were recorded as major constituents. The essential oil of P. graveolens leaves showed concentration dependant inhibition of α-glucosidase enzyme ranging from 28.13±1.41 to 74.24±2.53 µg/mL for concentration ranging from 31.25 to 1000 µg/mL. The IC50 values for of P. graveolens and acarbose were found as 93.72±4.76 and 80.4±2.17 µg/mL, respectively against the α-glucosidase enzyme. The study finding explores the chemical components of P. graveolens growing in the Iraqi Kurdistan region and scientifically supported its possible use in diabetic patients for controlling postprandial hyperglycemia.

The highest level of total volatile fatty acids (tVFA) was found when lemon seed essential oil and the lowest level when flaxseed essential oil was used. The lucerne silages treated with essential oils had the highest crude protein contents (<em>p </em>&lt; 0.01). Untreated lucerne silage had the highest level of gas production compared to lucerne silage treated with lemon seed and flaxseed essential oils (<em>p </em>&lt; 0.01). The essential oil additives increased the aerobic stability of the silage. It can be concluded that the use of essential oil additive in the preparation of high quality lucerne silage, can improves the quality and nutritive value of silages.</p>

AbstractEmulsion is an efficient encapsulation tool for enhancing the functional properties of essential oils (EOs). Herein, two two-dimensional cinnamon essential oil emulsions (from micro- to nanoscales) were emulsified by hydroxypropyl methylcellulose, and their antimicrobial and physicochemical properties were investigated. For the models of Escherichia coli CGMCC 1.0907, Salmonella enterica subsp. Enterica serovar Typhi (CICC 10867), Staphylococcus aureus CGMCC 1.0089, and Listeria monocytogene CGMCC 1.9144, the minimum inhibitory concentration (MIC) of the nanoemulsion was 31.25 μL/mL compared to that of the microemulsion (62.5–125 μL/mL) and pure oil (125–250 μL/mL), indicating the superiority of nanoemulsion as an antibacterial agent. The results showed that the highest activity was seen in the gram-positive L. monocytogenes whereas the lowest was in the gram-negative S. enterica. The identified properties of HPMC (hydroxypropyl methylcellulose) provide the potential for emulsifying and enhancing essential oils in light industries, especially for food processing.

Gas chromatography/mass spectroscopy analysis was performed to identify the chemical components of three extracted essential oils including thyme, marjoram, and sage. The antibacterial activity of the extracted essential oils against Pseudomonas aeruginosa (ATCC 9027) was investigated using disc diffusion assay, either alone or in combination with standard antibiotics (piperacillin, cefepime, meropenem, gentamicin, and norfloxacin). Results showed that the studied oils exhibited a variety of activities against the tested bacterium. Thyme oil was the most active followed by marjoram oil, whereas sage displayed no activity towards the tested organism. Thyme oil enhanced the antibacterial activity of cell wall targeting antibiotics (piperacillin, cefepime, and meropenem) by more than twofold. Marjoram oil potentiated the activity of all the tested antibiotics except norfloxacin. Sage, despite its inactivity against pseudomonas, synergistically enhanced the activity of piperacillin, meropenem, and gentamicin. Thyme essential oil, containing thymol as a major component (33.6%), exhibited higher activity alone or in combination with antibiotics than marjoram which contained alcoholic terpenes or sage essential oil that contained 1,8-cineole as its major component (29%). The investigated oils, as natural bioactive agents, may be used to enhance the activity of antibiotics towards pseudomonas.
