Description
Any unsaturated hydrocarbon of the formula C10H16 found in essential oils and oleoresins. Terpenes are based on five carbon isoprene unit. They are classified as monocyclic (dipentene), dicyclic (pinene) or aliphatic (myrcene). Examples of terpene derivatives, or terpenoids are: Camphor, Menthol, Terpineol, Borneol, and geraniol.
