Nutmeg oil is a volatile essential oil from nutmeg (Myristica fragrans). The oil is colorless or light yellow and smells and tastes of nutmeg. It contains numerous components of interest to the oleochemical industry. The essential oil consists of approximately 90% terpene hydrocarbons. Prominent components are sabinene, α-pinene, β-pinene and limonene. A major oxygen-containing component is terpinen-4-ol. The oil also contain small amounts of various phenolic compounds and aromatic ethers, e.g. myristicin, elemicin, safrole and methyl eugenol. The phenolic fraction is considered main contributor to the characteristic nutmeg odor. Myristicin and elemicin are suspected to be responsible for the hallucinogenic properties of nutmeg oil.
