Plant commercial essential oils

Lavender oil is one of the most valuable aromatherapy oils, its anti-bacterial and anti-fungal activities can be explained by main components such as linalool, linalyl acetate, lavandulol, geraniol, or eucalyptol. The aim of the study was to assess the anti-microbial effects of two different lavender oils on a mixed microbiota from facial skin. The commercial lavender oil and essential lavender oil from the Crimean Peninsula, whose chemical composition and activity are yet to be published, were used. Both oils were analysed by gas chromatography coupled to mass spectrometry. The composition and properties of studied oils were significantly different.

An essential oil is a concentrated hydrophobic liquid containing volatile easily evaporated at normal temperatures chemical compounds from plants. Essential oils are also known as volatile oils , ethereal oils , aetherolea , or simply as the oil of the plant from which they were extracted, such as oil of clove. An essential oil is "essential" in the sense that it contains the "essence of" the plant's fragrance—the characteristic fragrance of the plant from which it is derived. Essential oils are generally extracted by distillation , often by using steam. Other processes include expression , solvent extraction , sfumatura , absolute oil extraction, resin tapping, wax embedding, and cold pressing. They are used in perfumes , cosmetics , soaps and other products, for flavoring food and drink, and for adding scents to incense and household cleaning products.

Dragar, VA , 'A preliminary survey of selected species of endemic plants to determine commercial cropping potential for essential oils', Coursework Master thesis, University of Tasmania. This work was embarked upon as a preliminary survey of the Tasmanian endemic essential-oil-bearing plants, with a view to locating species which may be suitable for commercial production of oil. Initially, twenty plant species were selected as having been observed to contain an essential oil. The species were : Bedfordia salicina, Beyeria viscosa, Callitris tasmanica, Cassinia aculeata, Drimys lanceolata also known as Tasmannia lanceolata , Eriostemon virgatus, Kunzea ambigua, Leptospermum glaucescens, Leptospermum lanigerum, Leptospermum scoparium, Melaleuca squamea, Melaleuca squarrosa, Olearia argophylla, Olearia phlogopappa, Phebalium squameum, Prostanthera lasianthos, Senecia linearifolius and Zieria arborescens. Material from these species was taken for steam distillation and solvent extraction, and the oil samples, thus obtained, were analysed by GC-MS. In addition, data on yields of oil were compiled, in order that comparisons between species could be made. The number of species under investigation was reduced to ten, by excluding those that did not possess a persistent or powerfully pleasant odour. The other major criterion used in determining which species may be of commercial value was oil yield, which was not to be less than 0.

Essential oils are generally regarded as high value, low volume commodities and yet many developing countries import large quantities of oils to meet local demand for use in soaps, detergents, perfumes and other household goods. With agriculture providing the main source of income for rural communities, diversification to growing and even processing agricultural plants for essential oils, can help protect farmers from unstable prices of cash crops. However, despite the increasing trend for alternative products and therapies, such as massage, aromatherapy and acupuncture, which are currently taking up a larger share of the oils market, inconsistent buying from importing traders can leave farmers with a crop they cannot sell. Essentials oils volatile oils can be extracted from the leaves, flowers, seeds, bark, roots from a wide variety of plants and the rind of certain fruits. An estimated 3, essential oils are known of which approximately are of commercial importance. The majority are obtained from agricultural plants but a number of oils are collected in commercial quantities from wild sources e. On account of their aroma and highly volatile nature, essential oils have been traditionally used as basic raw materials in perfumes and flavourings: Sandalwood, for example, has been used in perfumery for over 4, years. However, oils are also used for medicinal purposes and even as insect repellents or insecticides.

The essential oil from a particular species of plant may vary depending on where it has been grown By hand, no commercial mechanical harvesting is known.

Everything you need to know about essential oils

Essential oils are concentrated extracts of various plants. Practitioners use them in natural and alternative health practices, such as aromatherapy and naturopathy. Many plants contain some potentially helpful compounds. However, in many cases, there is not enough evidence to suggest their use as a treatment or cure for ailments. In this article, learn more about the uses, benefits, and potential side effects of essential oils. Essential oils are liquid extracts of various potentially beneficial plants. Manufacturing processes can extract the useful compounds from these plants. Essential oils often have a much stronger smell than the plants they come from and contain higher levels of active ingredients. This has to do with the amount of plant matter required to make essential oil.

Essential oils, called volatile oils or ethereal oils, are natural metabolic secretions of plants, the role of which is not yet fully understood by science. Some specialists consider them to be true plant hormones, fluid manifestations of the immune system of plants, in the sense that they contribute to the removal of pests, attracting, instead, pollinating agents, which are some insects and birds. Small, light—colored spherical structures, is, in fact, modified filaments, which behave like some secretory glands of essential volatile oils. They are the ones who give the fragrance of the aromatic plant and have, in the case of salvation, medicinal curative properties, such as fever reduction, blood cleansing, and relieving pain.

The use of essential oils EOs and their components is known since long in traditional medicine and aromatherapy for the management of various diseases, and is further increased in the recent times. The neuroprotective and anti-aging potentials of EOs and their possible mechanism of actions were evaluated by numerous researchers around the globe.
