Ocimenes are a group of 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 cis-3,7-dimethyl-1,3,7-octatriene. β-ocimene is trans-3,7-dimethyl-1,3,6-octatriene. β-ocimene exists in two stereoisomeric forms, cis and trans, with respect to the central double bond.

Besides exhibiting antioxidant and anti-inflammatory activity, research suggests that beta-ocimene may have mild sedative or relaxing effects, which could contribute to its use in traditional medicine and aromatherapy.

it is also one of the most common terpenes found in cannabis plants. β-ocimene is a terpene responsible for some of the sweet and herbaceous flavors of certain cannabis strains, and it can also add citrusy and woody undertones.
