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.
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.
In bloom, the plant grows to about 1 meter (3 ft) in height and has small, pink, bell-shaped flowers. It is found at an altitude of about 3,000 to 5,000 m (9,800 to 16,400 ft). Its rhizomes can be crushed and distilled into an intensely aromatic, amber-colored essential oil with a thick consistency.
Cistus ladanifer leaves and flowers used in perfumery. Citron oil, used in Ayurveda and perfumery. Citronella oil, from a plant related to lemon grass is used as an insect repellent; Clary Sage oil, used in perfumery and as an additive flavoring in some alcoholic beverages.

The compound evergreen leaves are pinnate, smooth and glossy, and 13–21 cm (5–8.5 in) long. Leaflets are oval, pointed and with wavy margins. The flower is drooping, long-stalked, with six narrow, greenish-yellow (rarely pink) petals, rather like a sea star in appearance, and yields a highly fragrant essential oil. Its pollen is shed as ...
Its oil is known as linseed oil. In addition to referring to the plant, the word "flax" may refer to the unspun fibers of the flax plant. The plant species is known only as a cultivated plant [3] and appears to have been domesticated just once from the wild species Linum bienne, called pale flax. [4]
The insect pests can feed on developing pods to lay eggs inside and eat the developing seeds, bore into the plant's stem and feed on pollen, leaves and flowers. Synthetic pyrethroid insecticides are the main attack vector against insect pests though there is a large-scale use of prophylactic insecticides in many countries. [33]
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.
