52 , REPORT OF SCHIMMEL & Co. OCTOBER 1914/APRIL 1915. 
Besides wood from the trunk, we have now been able to distil roots, as well as 
fruits, and have come to the following results: Four samples of trunk wood yielded | 
between 1,03 and 2,06 p.c. of oil of the following values: diso 0,958 to 0,963; ap + 83°45’ 
to + 104° 12’; np»o 1,49695 to 1,50111; soluble in 2,5 to.4 volumes and more of 
70 p.c. alcohol, in one instance with slight opalescence. Quantitatively the aldehydes ~ 
of these, as well as of the other oils, did not react with sodium hydrogen sulphite, 
but they did with neutral sulphite; in this manner between 75 and 80 p.c. of aldehydes 
were found. The acid v., determined in one oil only, was 4,4; ester v. 47,1. 
Wood from the roots yielded 0,5 p.c. of oil of the following properties: diso 0,9667; 
dy +126°15'; np»o 1,50383; aldehyde percentage (sulphite method) 92,5 p.c.; soluble 
in 2,5 volumes and more of 70 p.c. alcohol. 
The distillate obtained from whole fruits (yield 0,5 p.c.) showed the following 
figures: diso 0,9528; @p + 50° 16’; nps00 1,49554; aldehyde content (sulphite method) 49 p.c. 
It only dissolved in 0,3 volume and more of 90 p.c. alcohol. Of 80 p.c. alcohol not 
even 10 volumes sufficed to produce solution. 
The almond-shaped kernels contained considerably more oil, namely 1,38 p.c.: 
dis0 1,0044; &p + 87°; Nps»o 1,50614; acid v. 7,3; ester v. 110,4; not completely soluble 
in 10 volumes of 70 p.c. alcohol; soluble in 0,5 volume of 80 p.c. alcohol. On more 
being added, opalescence set in. 
All these oiis were of light to dark yellow colour and, with the exception of the 
oil from the fruits, had the characteristic odour of perillaldehyde. ; 
Himalaya cedar Oil. Some time ago, the Forest Research Institute and College 
in Dehra Dun sent us an oil called Deodar oil for vatuation. This oil had been obtained 
by distillation with steam from the saw-dust of the Himalaya cedar /Cedrus Deodaya 
(Roxb.), Loud., C. Libani, Barrel. var. Deodara/. It possessed a light brown colour and 
a pleasant, balsamic odour. A close examination gave the following results: dis0 0,9530; 
a + 53° 8’; np» 1,51565; acid. v. 2,9; ester v. 14,9; ester v. after acetylation 39,2; not 
completely soluble in 10 volumes of 90 p.c. alcohol, soluble in every proportion of 
95 p.c. alcohol. Under a pressure of 760 mm, 87 p.c. of the oil passed over between 
258 to 295°. The first fractions of the distillate (258 to 205°, 14 p.c.) contained a body 
which yielded a semicarbazone of the m. p. 158°, and which is perhaps identical with 
the ketone’) found in Atlas cedar oil. But the largest part of the oil consists of 
sesquiterpene, about the identity of which we have not ascertained anything further 
as yet. A test for cadinene yielded no positive result. 
The wood of the Himalaya cedar is largely used in India for building PurpOsee 
as well as for the manufacture of railway sleepers. 
Oil from Libocedrus decurrens. Some time ago our branch house in New York 
sent us an oil from the needles of Libocedrus decurrens, Torr., a conifer occurring chiefly 
in California’). Its odour reminds of savin oil. diso 0,8756; @ — 0° 51’; npao 1,47544; 
acid v. 0,9; ester v. 4,6; soluble in 7 volumes of 90 p.c. alcohol and more, with turbidity. 
22 p.c. of the oil boiled from 158 to 160° (dis0 0,8640; ep) — 18° 40’) and contained 
|-a-pinene (nitrolbenzylamine, m. p. 124°). When trying to prove 6-pinene in the fractions ~ 
of b. p. 60 to 67,5° (16 mm) by oxidation to nopinic acid, an acid melting at about 103° —
