 The fruits of the tree are important as the source of the spices nutmeg (germ. Muskatnuss) and mace (germ. Macis).
-"Nutmeg is not a nut, but the kernel of an apricot-like fruit. Mace is an arillus, a thin leathery tissue between the stone and the pulp; it is bright red to purple when harvested, but after drying changes to amber... Both spices are strongly aromatic, resinous and warm in taste. Mace is generally said to have a finer aroma than nutmeg, but the difference is small. Nutmeg quickly loses its fragrance when ground; therefore, the necessary amount should be grated from a whole nut immediately before usage."

 An extract of nutmeg (liquid CO2; 90 bar, 296K) contained fatty oils (36.4-57.4% with mainly saturated fatty acids, thereof myristic acid 40%) and essential oil. Major components of the essential oil fraction were sabinene (36.6%) β-pinene (10.1%), α-pinene (11.0 %), and myristicin (6.9%), with safrole (1.0%). \\

 "The essential oil is known to have spasmolytic activity and relieves stomach cramps and flatulence. The addictive and hallucinogenic effects are ascribed to myristicin and elemicin that are converted to amphetamin-like compounds [in the body]." \\

+"The essential oil content ranged from 3.9% (A9/116) to 16.5% (A9/18) (v Iw) in nutmeg and 6% (A9/107) to 26.1% (A9/18) in mace... Myristicin content ranged from 1.1 % (A9/20) to 45.6% (A11/21) in nutmeg oil and 0.21% (A9/13) to 36.6% (A4/117) in mace oil; the elemicin content ranged from 1.0% (A4/22) to 29.7% (A11/26) in nutmeg oil and 1.0% (A9 II) to 30.2 % (A4/12) in mace oil.

 "An amount of 4.92 g of the essential oil was obtained from 100 g of nutmeg [three-hour hydrodistillation]. Major components of nutmeg oil are terpenes, terpene alcohols and phenolic ethers. The monoterpene hydrocarbons, β-pinene (23.9 %), α-pinene (17.2 %), and limonene (7.5 %), constituted the main fraction of nutmeg oil. The major phenolic ether is myristicin (16.2 %), accompanied by safrole (3.9 %) and methyl eugenol (1.8 %)." \\
 The main aglycones of glycosidically bound volatiles identified in nutmeg are isoeugenol (46.1 %) and methoxyeugenol (27.7 %). \\
