Juniperus procera, Hochst. is a tree that is found in the mountains of Abyssinia and Usambara also on the Kilimandjaro and Kenia. It grows at an altitude of 1500 to 3000 m. and in Usambara constitutes extended forests. Anatomically, the wood reveals great resemblance to That of Juniperus virginiana.
From the sawdust of the wood, which is used in the manufacture of lead pencils, Schimmel & Co.1) obtained 3,2 p.c. of a dark yellowish-brown oil with an odor reminding very much of vetiver, and which possessed the following constants: d160 0,9876; nD20o 1,50893; A. V. 14,9; E. V. 8,4; E. V. after acetylation 70. Inasmuch as the oil was too dark, the optical rotation was determined for a solution of equal volumes of alcohol and oil. For a 20 mm. tube it was found to be - 3° 43', which corresponds to - 37° 10' for the original oil in a 100 mm. tube. The oil was soluble in 1,6 vols, and more of 80 p.c. alcohol and in 1/2 vols-and more of 90 p.c. alcohol.
From the comminuted small boards 3,24 p.c. of oil were obtained which at ordinary temperature consisted of a semi-solid mass permeated with crystals. The oil from which the crystals had been removed had the following properties: d15 o1,0289; nD20o 1,51011; A. V. 27,06; E.V. 7,93; E. V. after acetylation 89,6. In this case also it was impossible to determine the optical rotation of the original oil. Diluted with an equal volume of alcohol, it showed -3° 15' in a 20 mm. tube (= - 32° 30' for the original oil in a 100 mm. tube). It is soluble in 2 vol. and more of 80 p.c. alcohol and in 1/2 vol. of 90 p.c. alcohol. The crystals consisted of cedar camphor. Recrystallized from alcohol, they melted at 86 to 87°; [a]D + 10,12° (2,5517 g. solution dissolved in 25 cc. of chloroform). The phenyl urethane melted at 106,5°.
