Chemistry:Pinocarvone
From HandWiki
Pinocarvone is a terpenoid. Structurally, it is a bicyclic ketone.
Occurrence
Pinocarvone is an important component in the essential oils of Eucalyptus globulus.[1] It is also found at a few percent in essential oils of other eucalyptus species.[2] In several studies, it has been detected as a component of 25% or even 36% in hyssop oil.[3]
Pinocarvone is also present in the pheromone of the Western Pine Beetle (Dendroctonus brevicomis) along with frontalin, verbenone, and myrtenol.[4]
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.[1]
