The essential oil of the flower is obtained through steam distillation of the flowers and separated into different grades (extra, 1, 2, or 3) according to when the distillates are obtained. The main aromatic components of ylang-ylang oil are benzyl acetate, linalool, p-cresyl methyl ether, and methyl benzoate, responsible for its characteristic ...
Davana essential oil. The leaves and flowers yield an essential oil known as oil of Davana. Several species yield essential oil and some are used as fodder, some of them are a source of the anthelmintic chemical santonin. Davana blossoms are offered to Shiva, the God of Transformation, by the devotees, and decorate his altar throughout the day.
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, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove.
There are three primary types of plant oil, differing both the means of extracting the relevant parts of the plant, and in the nature of the resulting oil: Vegetable fats and oils were historically extracted by putting part of the plant under pressure, squeezing out the oil. Macerated oils consist of a base oil to which parts of plants are added.
It is also used extensively as a decorative plant in parks and other public areas, particularly as a "dot plant" in traditional bedding schemes. If sown early, under glass, and kept at a temperature of around 20 °C (68 °F) until planted out, the castor oil plant can reach a height of 2–3 metres (6.6–9.8 ft) in a year.
The water which condenses along with the oil is drained off and redistilled, cohobation, in order to obtain the water-soluble fractions of the rose oil such as phenethyl alcohol which are a vital component of the aroma and which make up the large bulk, 80%, of the oil. The two oils are combined and make the final rose attar.
There are three types of clove oil: [5] Bud oil is derived from the flower-buds of S. aromaticum. It consists of 60–90% eugenol, eugenol acetate, caryophyllene and other minor constituents. Leaf oil is derived from the leaves of S. aromaticum. It consists of 70–82% eugenol, and some amounts of beta Caryophyllene and alpha Humulene.
The distillate will contain compounds that vaporize at or below the temperature of distillation. The actual chemical components of these orange herbal distillates have not yet been fully identified, but plant distillates will usually contain essential oil compounds as well as organic acids and other water-soluble plant components.
