    ABSTRACT: Ventilation systems often host bacteria and fungi that may be dangerous for the health of exposed people. Essential oils are one means among others to prevent microbial development. Used as a basis for many traditional therapies, these odorant plant extracts have been studied extensively in the medical domain and their effectiveness in the treatment of numerous pathologies has been demonstrated. As opposed to most antimicrobial agents currently used for air disinfection, essential oils are low in toxicity. With a view to proposing an indoor air purification method based on the germicidal and odorant properties of essential oils, we selected a pathogenic test strain and followed the AFNOR NF T72-281 standard. This protocol evaluates on a surfaces level, the disinfection efficacy of volatile antimicrobial agents on airborne contaminations such as bacteria, fungi and spores. The protocol was applied to one of the most active essential oils, mountain savory, and also to a solution of formaldehyde at a concentration of 40% called formol, a chemical reference in hospitals. We demonstrated that the gaseous phase of the essential oil of savory has a lethal effect on Staphylococcus aureus and it has a satisfying bacteria reduction rate close to the total disinfection achieved with evaporated formol.

    ABSTRACT: The species of Cymbopogon giganteus is widely used in traditional medicine against several diseases. This study reports the inhibitory effect produced by the chemical constituents of the essential oil from leaves of C. giganteus of Benin, in vitro on 5-lipoxygenase. We assayed the antiradical scavenging activity of the sample by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method.The essential oil of C. giganteus was analyzed by GC and GC/MS. The major constituents were: trans-p-1(7),8-menthadien-2-ol (22.3%), cis-p-1(7),8-menthadien-2-ol (19.9%), trans-p-2,8-menthadien-1-ol (14.3%), cis-p-2,8-menthadien-1-ol (10.1%).

    ABSTRACT: An evaluation was made of the usefulness of fragrance application in discontinuing the long-term use of hypnotic benzodiazepines in primary insomniacs with low-dose dependence. Based on the results of pentobarbital sleep time in rats, we made a new fragrance consisting primarily of sandalwood (35%), juniper berry (12%), rose (8%) and orris (6%). This mixed fragrance was found to prolong the pentobarbital sleep time in rats. A total of 42 outpatients with low-dose dependence on hypnotic benzodiazepines, all of whom met DSM-IV criteria for primary insomnia, participated in the study. In advance, all subjects attempted to reduce the doses of drugs gradually (25% reduction a week if possible) and 29 subjects who had failed to do so at all participated in the study on the application of fragrance. A mixed fragrance described above was used. A gradual tapering of hypnotic benzodiazepines (25% reduction a week if possible) was attempted while sniffing the fragrance in bed. The application of fragrance reduced the doses of hypnotic benzodiazepines in 26 of 29 subjects and 12 subjects did not require any drug for sound sleep. The present study indicated that a kind of fragrance may prove effective as an alternative to hypnotic benzodiazepines.

    ABSTRACT: Thirty-six aromatic herbs were cultivated in Chichibu district of Japan, and their volatile constituents were elucidated by GC/MS analysis using ethyl acetate extract of the herbs to determine the chemotype. The volatile compositions of 30 herbs were similar to those of commercial essential oils and literature except for Eupatorium japonicum, marjoram, Japanese mint, oregano and yarrow. The volatile composition of Eupatorium laciniatum was first elucidated in this study. The vapour activity of the ethyl acetate extracts was determined by box vapour assay against Trichophyton mentagrophytes to search for the anti-infectious herbs to treat tinea pedis by vapour therapy. For comparison, the contact activity was determined by agar diffusion assay. The results showed that most of herbs exhibited potent vapour activity against the test organism, of which Roman chamomile, curry plant, hyssop, lavandin, marjoram sweet, orange mint, spearmint, monarda, oregano, rosemary, rue sage, tansy, tarragon, thyme common and yarrow showed the most potent activity. Most of the activity was correlated with the contact activity and also with main active ingredients of the herbs, but no correlation was found for curry plant, oregano, rosemary, rue, sage and yarrow.

    ABSTRACT: A selection of essential oils and components were tested in vitro for potential immunomodulating effects on natural killer cell activity (NKCA) and lymphocyte activation through CD69 expression.Matricaria recutita, Boswellia carteri, Pelargonium graveolens, Lavandula angustifolia, Citrus limon, Melaleuca alternifolia, Melaleuca viridiflora, Santalum spicatum, Cedrus atlantica, and Thymus vulgaris ct. linalool essential oils were solubilised with ethanol and methylated â-cyclodextrin 1:5:25 (w/v) and pre-incubated at 10 ìg/mL and 2 ìg/mL (M. alternifolia and C. atlantica: 2 and 1 ìg/mL) with human peripheral blood mononuclear cells (PBMC) for 2 h. They were then incubated for 2 h with K562 target cells before determination of NKCA. The first 6 of these oils were similarly solubilised, pre-incubated for 2 h with aliquots of whole blood, then incubated with PHA for 4 h before measurement of CD69 antigen expression. Reference components á-pinene, S-(−)-limonene, linalool, geraniol, thymol, 1,8-cineole, linalyl acetate, eugenol, (+)-terpinen-4-ol, and trans-caryophyllene were solubilised with ethanol 1:5 and similarly tested.Dose-dependent stimulation of NKCA was found for trans-caryophyllene and linalyl acetate. No other effects of essential oils or components were found in these assays. Methylated â-cyclodextrin proved to be a less than ideal agent for enhancing solubility of essential oils, due to substantial effects on assay outcomes.

    ABSTRACT: We examined whether it was possible to practice hygienic massage by using six essential oils (eucalyptus, lavender, niaouli, sage, tea tree, and thyme linalool) that in previous studies or anecdotally have been found to have antibacterial effects. First, to determine the inhibitory properties of the six essential oils against 4.80 × 105 colony forming units (CFU) of strain ATCC-25923 of Staphylococcus aureus, we used a disc method to measure the inhibition zones. Niaouli and eucalyptus showed higher growth inhibitory effects. We then examined the results of using these two essential oils in seven different massage sessions. The niaouli and eucalyptus were each diluted to 1%, 3%, or 6% v/v with jojoba oil base and jojoba oil without any essential oil was used as a control. Bacterial samples were taken from the therapist’s palms and the subject’s skin, and the surviving bacteria were counted.The antibacterial effects were correlated in vitro with the concentration of the essential oil and massage sessions with niaouli oil were more hygienic than those with eucalyptus oil.

    ABSTRACT: Adsorption of the major constituents of lavender, tea tree, lemongrass and thyme thymol essential oils on hairless mouse skin was determined in an aromatic bath. Adsorption occurred in a concentration-dependent manner. Sesquiterpene hydrocarbons showed the most dominant adsorption, especially in dilute solution. This was followed by the hydrophobic monoterpene hydrocarbon and ester. The relatively hydrophilic monoterpene alcohol, phenol and aldehyde constituents were poorly adsorbed. The same tendency was observed on hairy mice, mouse hairs, guinea pig hairs and human hairs. This selective adsorption of sesquiterpenes was not observed on natural rubber but observed on keratin, a major protein forming skin and hairs. When examined using the authentic compounds, the sesquiterpene hydrocarbon (β-caryophyllene) and the sesquiterpenols (farnesol, nerolidol, and bisabolol) exhibited the highest adsorption, while the monoterpene limonene and linalyl acetate showed moderate adsorption, and the monoterpenic camphor, linalool, perillaldehyde, and thymol showed low adsorption. Human hairs were suggested to be an alternative to mouse skin for adsorption studies of essential oils.

    ABSTRACT: Although there is considerable anecdotal information about the antibacterial activity of lavender oils, much of this has not been substantiated by scientific or clinical evidence. In this study we assessed the activity of lavender essential oils, hydrosols and aqueous and ethanolic foliage extracts from a range of Australian grown Lavandula species. The results support the anecdotal use of lavender oils as antibacterial agents and demonstrated that some oils which had previously not been investigated (e.g., Lavandula heterophylla) display good antibacterial activity against a range of bacteria including Streptococcus pyogenes, Staphylococcus aureus, MRSA, Citrobacter freundii, Proteus vulgaris, Escherichia coli, VRE and Propionibacterium acnes. Pseudomonas aeruginosa was the only bacterium not susceptible to any essential oil. There was considerable variability in the activity of the essential oils however; no one oil produced the highest level of antibacterial activity against all bacteria. No correlation was observed between the percentage of major chemical components and antibacterial activity. The lavender hydrosols and aqueous foliage extracts did not have any antibacterial activity. Six of the ethanolic extracts displayed activity against Pr. vulgaris but no activity against any other organism. Further work is required to determine whether these in vitro results will be realised in a clinical environment but it is clear that not all lavenders are equal in terms of their antibacterial properties.

    ABSTRACT: Many species of Thymus have been widely used in Algerian folk medicine as astringent, expectorant and cicatrising agents. This study was designed to investigate for the first time the essential oil of the aerial parts of wild growing Thymus algeriensis endemic in North Africa. The volatile oil obtained by hydrodistillation was characterized by the physico-chemical properties, GC and GC/MS techniques. The yield of the oil was 1.13% (w/w), based on dry weight. Fifty-five components, representing 94.3% of the total oil, were identified. The oil was distinguished by its high content of oxygenated monoterpenes (79.5%) and was found to possess the following major components: linalool (47.3%), thymol (29.2%) and p-cymene (6.8%). Furthermore, the oil was tested for antimicrobial activity against four bacteria, two fungi and two yeasts. This oil exhibited a significant in vitro antimicrobial activity against Bacillus subtilis (MIC = 0.5 μL/mL), as well as against all yeast and all filamentous fungi tested (MIC = 0.5 and 1.0 μL/mL).
