Upon the distillation of the seeds of Monodora grandiflora (author?) (family Anonaceae), which grows wild in Africa, R.Leim-bach") obtained about 30 p.c. of oil with the following constants: d15o0,8574; aD - 46o 15'; A. V. 3,9; S.V. 7 to 12; soluble in 31/2 vol. of 90 p.c. alcohol. It is a mobile, light yellow liquid, has an odor of cymene, and its taste is at first aromatic, then bitter.

In the lowest fraction the presence of l-pheIlandrene (m.p. of nitrosite 108 to 110°) was established. This fraction probably also contained a small amount of camphene. In fraction 70 to 85° (20 mm.) the presence of cymone was established by its oxidation to hydroxy isopropyl benzoic acid. The highest boiling fractions contain palmitic acid and probably some carvacrol. The principal constituent, however, is a compound C10H16O, a light yellow oil (b. p. 130 to 154° under 30 mm. pressure; d15o 0,9351; aD - 9° 14') to which the aromatic odor of the oil is partly due. In addition they contain a sesquiterpene (b.p. 260 to 270°; d16o 0,9138; aD + 24°; nD16o 1,50513) that has not been further characterized and a solid substance of unknown composition melting at 160 to 163°.
