Terpinene is a monoterpene chemical compound, which is classified into four isomers: alpha-terpinene, beta-terpinene, gamma-terpinene, and delta-terpinene. These isomers are commonly found in a variety of plants and contribute to their aromatic characteristics.

Chemistry

Terpinene is part of the terpene family, which are hydrocarbons that consist of multiple isoprene units. The four isomers of terpinene differ in the position of the double bonds and are named according to the IUPAC nomenclature.

• Alpha-Terpinene has been isolated from cardamom and marjoram oils, and from other natural sources. It is also formed from the hydration of limonene.
• Beta-Terpinene has no known natural source, but can be prepared from sabinene.
• Gamma-Terpinene and Delta-Terpinene are natural and have been isolated from a variety of plant sources.

Uses

Terpinene is commonly used in the production of perfumes and cosmetics due to its aromatic properties. It is also used as a flavoring agent in food and beverages. In addition, terpinene has been studied for its potential medicinal properties, including its anti-inflammatory, antioxidant, and anticancer effects.
