Ocimene refers to several isomeric hydrocarbons. The ocimenes are monoterpenes found within a variety of plants and fruits. α-Ocimene and the two β-ocimenes differ in the position of the isolated double bond: it is terminal in the alpha isomer. α-Ocimene is 3,7-dimethyl-1,3,7-octatriene. β-Ocimene is 3,7-dimethyl-1,3,6-octatriene. β-Ocimene exist in two stereoisomeric forms, cis and trans, with respect to the central double bond. The ocimenes are often found naturally as mixtures of the various forms. The mixture (as well as the pure compounds) is an oil with a pleasant odor. It is used in perfumery. Like the related acyclic terpene myrcene, ocimenes are unstable in air.[2] Like other terpenes, the ocimens are nearly insoluble in water, but soluble in common organic solvents.
