Chemical Information

FooDB Name

alpha-Terpinene

Description

Constituent of many essential oils e.g. Citrus, Eucalyptus and Juniperus subspecies Oil of Litsea ceylanica is a major source (20%). Flavouring agent The terpinenes are three isomeric hydrocarbons that are classified as terpenes. They each have the same molecular formula and carbon framework, but they differ in the position of carbon-carbon double bonds. alpha-Terpinene has been isolated from cardamom and marjoram oils, and from other natural sources. beta-Terpinene has no known natural source, but has been prepared synthetically from sabinene. gamma-Terpinene is natural and has been isolated from a variety of plant sources. alpha-Terpinene is found in many foods, some of which are common oregano, allspice, cardamom, and sweet bay.

Classification

Description

Belongs to the class of organic compounds known as menthane monoterpenoids. These are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes.
