Common Name4,8-Epoxy-p-menth-1-ene
DescriptionTerpinolene oxide also known as 4,8-Epoxy-p-menth-1-ene or 4,8-Terpinolene oxide, is an oxidation product of the terpenoid known as Terpinolene. It belongs to the class of organic compounds known as menthane monoterpenoids. These are monoterpenoids with a structure based on the o-, m-, or p-menthane backbone. P-menthane consists of the cyclohexane ring with a methyl group and a (2-methyl)-propyl group at the 1 and 4 ring position, respectively. The o- and m- menthanes are much rarer, and presumably arise by alkyl migration of p-menthanes. Monoterpenoids are terpenes that contain 10 carbon atoms and are comprised of two isoprene units. The biosynthesis of monoterpenes is known to occur mainly through the methyl-eritritol-phosphate (MEP) pathway in the plastids (PMID: 7640522 ). Geranyl diphosphate (GPP) is a key intermediate in the biosynthesis of cyclic monoterpenes. GPP undergoes several cyclization reactions to yield a diverse number of cyclic arrangements. Terpinolene oxide is an extremely weak basic (essentially neutral) compound (based on its pKa). Terpinolene oxide is a monoterpenoid found in cumin and isolated from Zanthoxylum piperitum (Japanese pepper tree). Terpinoline oxide is found in plants or plant products that produce terpinolene. Terpinolene is a sweet, citrus, and fresh tasting compound. Terpinolene is found, on average, in the highest concentration within a few different plants or plant foods, such as parsnips, nutmegs, and wild carrots and in a lower concentration in sweet bay, star anises, and turmerics. Terpinolene is also one of the dominant terpenoids found in cannabis plants (PMID: 6991645 ). There are more than 140 known terpenes in cannabis and the combination of these terepenoids produces the skunky, fruity odor characteristic of C. savita.
