Elemicin is aphenylpropene , a naturalorganic compound , and is a constituent of several plant species'essential oils .[ 1] [ 2]
Elemicin is a constituent of theoleoresin and the essential oil ofCanarium luzonicum (also referred to as elemi). Elemicin is named after this tree. One study found it to compose 2.4% of the fresh essential oil.[ 1] Elemicin is also present in the oils of the spicesnutmeg andmace , with it composing 2.4% and 10.5% of those oils respectively.[ 2] Structurally, elemicin is similar tomyristicin , differing only by myristicin's methyl group that joins the two oxygen atoms that make up its dioxymethy moiety, with both constituents being found in nutmeg and mace.
Elemicin was first isolated from elemi oil usingvacuum distillation . Specifically, the substance was collected between 162-165 °C at a reduced pressure of 10torr .[ 3] [ 4]
Elemicin has beensynthesized fromsyringol andallyl bromide usingWilliamson ether synthesis andClaisen rearrangement .[ 5] [ 6] Theelectrophilic aromatic substitution entering thepara -position was made possible by secondaryCope rearrangement .[ 7] This is due to syringol's allylaromatic ether being blocked by ethers in bothortho -positions. When blocked the allyl group migrates to thepara -position, in this case with yields above 85%.[ 8]
Elemicin has been used to synthesize the proto-alkaloid mescaline .[ 9]
Raw nutmeg causesanticholinergic -like effects, which are attributed to elemicin andmyristicin .[ 10] [ 11] Elemicin inhibits Stearoyl-CoA Desaturase 1 (SCD1) by metabolic activation. Elemicin is one of the main components in aromatic food and has antimicrobial, antioxidant, and antiviral activities. Elemicin possesses genotoxicity and carcinogenicity. Excess consumption of raw nutmeg results in delirium and disorientation.[ 12]
Elemicin's psychoactivity is still a point of research, however some research suggests it may act like an agonist of the5-HT2A receptors , similar to many psychedelics.[ 13] However, this is controversial as the psychoactive effects of elemicin and plants it is found in, such as nutmeg, seem to cause moredeliriant -like effects than psychedelic ones.[ 14]
