A volatile oil is a hydrophobic liquid containing volatile aroma compounds derived from plants. Volatile oils are also known as essential oils or simply as the "oil. The chemical composition of the hydrodistilled oils of the leaves of Psidium guajava L. (guava leaf) and Psidium cattleianum Sabine (strawberry guava) was. An essential oil is a concentrated hydrophobic liquid containing volatile (defined as "the tendency of a substance to vaporize") aroma 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.‎List of essential oils · ‎Lavender oil · ‎Aromatherapy · ‎Cannabis flower essential.

As chemical knowledge expanded in the late s and early s, many well-known chemists took part in the chemical characterization of essential oils. Improvement in knowledge of essential oils led to a sharp expansion in production, and use of the volatile oils in medicine became quite subordinate to uses in foodstuffs, beverages, and perfumes.

In the United States, volatile oil of turpentine and peppermint were produced before ; within the next several decades oils of four indigenous American plants became important commercially—namely, sassafraswormwoodwintergreen, and sweet birch.

Since many essential oils have been prepared, but only a few have attained volatile oil significance. Methods of production The first step in the isolation of essential oils is crushing or grinding the plant material to reduce the particle size and to rupture some of the cell volatile oil of oil-bearing glands.

Steam distillation is by far the most common and important method of production, and extraction with cold fat enfleurage or hot fat maceration is chiefly of historical importance. Three different methods of steam distillation are practiced.

Essential oil

Volatile oils are mixture of hydrocarbon terpenes, sesquiterpenes and polyterpenes and their oxygenated derivatives obtained from various volatile oil of the plant. Volatile oils evaporate on exposure to air at ordinary temperature and are the odorous constituents.

As volatile oil oils are responsible for the essence or odour of the plant they are also known as essential oils. Volatile oil oils, when fresh, are colourless liquids.


A few are crystalline or amorphous solid. On volatile oil standing, they become darker in colour, especially when exposed to air and direct sunlight.
