α-Myrcene is a monoterpene that is an uncommon[1] isomer of β-myrcene. It has been found in the essential oils of a few species, such as the Balkan Pine[2] and lemongrass.[3]
It differs from the β isomer by the position of one of the three alkene units. The two chemicals can be synthesized in a 3:1 α:β isomeric ratio by pyrolysis of the acetate ester of myrcenol.[4]
