Pinocarvone is a terpenoid. Structurally, it is a bicyclic ketone.

Occurrence

hyssop plant

Pinocarvone is an important component in the essential oils of Eucalyptus globulus.[2] It is also found at a few percent in essential oils of other eucalyptus species.[3] In several studies, it has been detected as a component of 25% or even 36% in hyssop oil.[4]

Pinocarvone is also present in the pheromone of the Western Pine Beetle (Dendroctonus brevicomis) along with frontalin, verbenone, and myrtenol.[5]

Properties and reactions

Under the influence of light or heat, pinocarvone polymerizes by reaction of its double bond to form a resin. Polymerization can also be carried out deliberately, for example by heating the compound in anisole.[2]
