Monodora myristica (Gaertn.) Dunal - syn. Annona myristica Gaertn. - Annonaceae
calabash nutmeg, African nurmeg, Jamaica nutmeg, ‘false’ nutmeg, Kalebassen-Muskatnußbaum

Large deciduous tree up to 35m high, native to West Africa, cultivated in the Caribbean; bark grey; leaves alternate, simple, up to 35cm, deep green on the upper side with paler green underneath; flowers suspended on long stalks, showy, large, waxy, fragrant; calyx lobes yellowish, splashed with red, frilled at the edges; petals pale yellow with purplish red spots; fruits large, woody, filled with brown seeds (1-2cm long) embedded in an aromatic pulp. „The seeds are the most economically important part of this tree. They are widely used in West Africa as a substitute for nutmeg in soups, stews and cakes. In traditional medicine, the seeds are used as a stimulant, stomachic and treatment for headaches.“

The essential oil of M.myristica fruits was mainly composed of monoterpene hydrocarbons, with α-phellandrene (48.8%), α-pinene (15.9%), limonene (8.7%), myrcene (7.9%) and α-thujene (6.3%) as the most important.

The essential oil of the seeds obtained by steam distillation (4.5%) was found to contain 75% monoterpene hydrocarbons. Major compounds were α-phellandrene (50%), α-pinene and myrcene.

M.myristica seeds have high protein (20%) and fatty oil content (21%). This seed oil is rich in glycerides of unsaturated fatty acids like linoleic acid (35%), oleic acid (33%), and arachidic acid (9%).

Hydrodistillation of fruits of M.myristica gave essential oils with yields of 1.8% (fruits collected in Chad) and 2.7% (Cameroon). Main components were Chad: α-phellandrene (52.7%), limonene (14.9%), β-phellandrene (4.2%), myrcene (5.2%), α-pinene (6.7%), α-thujene (2.4%) and linalool (2.4%); Cameroon: α-phellandrene (67.1%), β-phellandrene (3.0%), myrcene (3.8%), α-pinene (4.2%), limonene (1.8%), α-thujene (1.4%) and linalool (2.1%).
