myrcene
Also known as 7-methyl-3-methyleneocta-1,6-diene, 7-methyl-3-methylene-1,6-octadiene, 7-Methyl-3-methylene-1,6-octadiene (myrcene), FEMA 2762, 7-Methyl-3-methyleneoctadiene-(1,6), 3-Methylene-7-methyl-1,6-octadiene, 7-Methyl-3-methylideneocta-1,6-diene, 7-Methyl-3-methylene-1,6-octadiene (beta -myrcene)
Myrcene, or β-myrcene, is a monoterpene. A colorless oil, it occurs widely in essential oils. It is produced mainly semi-synthetically from Myrcia, from which it gets its name. It is an intermediate in the production of several fragrances. A less-common isomeric form, having one of the three alkene units in a different position, is α-myrcene.

==Production== thumb|244 px|left|Biosynthesis of myrcene from geranyl pyrophosphate. Myrcene is often produced commercially by the pyrolysis (400 °C) of β-pinene, which is obtained from turpentine. It is rarely obtained directly from plants.
