Therapeutic/Pharmaceutical applications of volatile oil
Volatile oils are used as flavoring and perfuming agents in pharmaceutical formulation, foods, beverages and cosmetics.
They are also used as medicinal agent such as carminative, anthelmintics, antiseptic, local anaesthetics, sedative, insect repellant etc,.
Volatile oils
Volatile oils are oils that are characterized by their volatility and failure to saponify. They evaporate when they are exposed to the air and thus are capable of distillation. They are derived from plant tissues. Thus, they may be produced naturally by extraction, particularly by distillation, often by using steam. They may also be made synthetically.
As medicines, volatile oils are used as stimulants, stomach aches, correctives, and carminatives. Other use of volatile oil is for purposes of flavoring (e.g., peppermint oil). But the most common use of volatile oil is for the production of perfumes, cosmetics, soaps, and the like.
Volatile oil is sometimes called an essential oil. An essential oil is known for being a concentrated hydrophobic liquid with plant-derived, volatile aroma compounds. It is referred to as essential since it contains what seems to be the essence of the plant’s fragrance

Mercurius is named after the roman god mercurius, the god of trade and science. The planet mercurius is named after the same god. Mercurius is sometimes called hydrargyrum, means ‘watery silver’. Its shine and colour are very similar to silver, but mercury is a fluid at room temperatures. The name quick silver is a translation of hydrargyrum, where the word quick describes its tendency to scatter away in all directions.
The droplets have a tendency to conglomerate to one big mass, but on being shaken they fall apart into countless little droplets again. It is used to ignite explosives, like mercury fulminate, the explosive character is one of its general themes.

- 1. VOLATILE OILS Shivani-Rawat B .Pharm[5-Semester] [U.I.P.S] UTTARANCHAL UNIVERSITY
- 2. VOLATILE OILS An essential oil is a concentrated hydrophobic liquid containing volatile aroma compounds from plants. It is also known as volatile oil. Example- clove oil.
- 3. PLANT PARTS HAVING VOLATILE OIL
- 4. CHEMISTRY OF VOLATILE OILS • Many volatile oils consist largely of terpenes. • Terpenes are defined as natural products whose structures may be divided into isoprene units. • These units arise from acetate via mevolonic acid pathway. • Isoprenes are 5 carbon compound having 2 unsaturated bond. • They are joined in head to tail fashion. • Isoprenes are also termed as hemi-terpenes.
- 5. PHYSICAL PROPERTIES OF VOLATILE OILS • Lighter than water. • Optically active and high refractive index. • Do not leave stains like fixed oils. • Soluble in organic solvents like alcohol ,chloroform. • Commonly found in the species -Labiatae -Rutaceae
- 6. THERAPEUTIC USES • As a counter irritant. • Improves local circulation • In aroma therapy[e.g. lavender and rosemary] • Eucalyptus oil administered as an inhalant. • Antiseptic, antibacterial, antifungal. • Thymol is used in mouth washes and gargles. • Reduce secretion of lungs in cough and asthma.
- 7. EXTRACTION METHOD ECUELLE METHOD Ecuelle method is used for the extraction of citrus oils where oils cells in rind are ruptured mechanically using pointed projections by twisting raw material over them in clockwise direction either mechanically or manually.
- 8. ENFLEURAGE It is used for extraction of delicate perfumes. In this method a layer of fat is spread over a glass plate and flower petal are placed over fat layer which absorbs volume. The exhausted petals are replaced by fresh petals. This process continues till the fatty layer is saturated volatile principle which is then extracted with lipid solvent.
- 9. STEAM DISTILLATION For substances which are usually injured by direct heat for example clove, cinnamon. Dried drug ground and covered with layer of water. Steam is passes through mixture, steam is generated by another chamber and piped into container having drug. The vapour contain oils are introduced in condensing chamber cooled and collected.
- 10. MACERATION The process in which properly communited drug is placed or permitted to soak in a solvent for specific period of time until the cellular structure is softened and penetrated by the solvent and soluble constituents are dissolved and extracted out. Example- tea bags.
- 11. SOLVENT EXTRACTION It is used in perfume industry and is an expensive method,. In this technique parts containing parts containing volatile oils are extracted directly by one of the organic solvent as they are crushed and mixed in the solvent and are mixed in the solvent and are separated by distillation. E.g.-oil of rose
