The cones of Abies Reginae Amaliae, Heldr. (Abies cepha-lonica, Lk.) growing in the forests of Arcadia contain so much volatile oil that it exudes upon the application of pressure. Upon distillation of the crushed fruit more that 16 p. c. of volatile oil have been obtained3).
Properties and Composition. The specific gravity of the oil is 0,868; its angle of rotation - 5°. It begins to boil at 156°, the boiling temperature remains constant for some time at 170° and rises finally up to 192°.
As shown upon elementary analysis, the oil consists mostly of terpenes C10H16.
