50 REPORT OF SCHIMMEL & Co. APRIL 1914. 
Although the cultivation of coriander in Russia has been declining for years, the 
crop of 1913 nevertheless was about 350000 kilos, the average yield of the area under 
cultivation having been very satisfactory. ; 
Moravia, Hungary and Thuringia have not produced any quantity of coriander 
worth mentioning; at any rate the product of those countries has long ceased to be 
of any importance for distilling purposes. 
Cubeb Oil. Plentiful offers of excellent raw material, rich in oil, have further 
depressed prices, and it has therefore been possible, in the course of the winter, to 
reduce the quotations repeatedly, the more so because the demand for oil of cubebs 
has kept within very moderate limits. : 
Oil of Cymbopogon coloratus. Oil from Cymbopogon coloratus, Stapf*) is one of 
those oils which had been very little investigated, until, quite recently, E. Goulding and 
J. C. Earl?) examined it thoroughly. The sample examined by them was distilled from 
green herb in the Fiji Islands. Yield about 0,35 p.c. d230,912, [@]px0 — 10,31°. The oil 
was found to contain 23 p.c. of geraniol (estimated by the phthalic anhydride method), 
and about 10 p.c. of geranyl acetate. For purposes of identification the geraniol was 
converted into the diphenylurethane, m. p. 82°. Other constituents identified were: 
7,0 p.c. terpenes (possibly a mixture of /-limonene with one or several other terpenes), 
40 p.c. aldehydes, principally citral, 0,75 p.c. acetic acid and 0,/5p.c. phenols. Among 
the phenol-like constituents was an inodorous body, m. p. 142°. 
Cypress Oil. Whenever an epidemic of whooping-cough breaks out, the medical 
faculty is glad to remember this well-established specialty, the action of which is 
positively astounding, especially in cases where the disease is still in its first stage. 
In making this statement it is of course presupposed that the pure distillate from 
branches of Cupressus sempervirens is employed, such as we prepare in our factory at 
Barréme, and not an oil made from those degenerate varieties which have none, or 
only a slight, medicinal efficiency. We shall be pleased to supply pharmacists with 
literature for distribution among the medical profession. 
Oil of Dacryodes hexandra. Many years ago we referred to a paper by A. More*) 
on oil from the resin of Dacryodes hexandra, Griseb. (N. O. Burseracee). According to 
More the resin, when distilled by steam, affords about 16 p.c. of a readily volatile oil, 
which distils over between 156 and 180°, leaving from 12 to 13 p.c. of residue. In 
the fraction boiling between 156 and 163°, More found J/-a-pinene (monohydrochloride, 
m. p. 128°), while the fraction boiling between 173 and 176°, when saturated with dry 
hydrochloric acid gas, afforded a hydrochloride, m. p. 71°, crystallising at — 10°, which 
fact pointed to the presence of sylvestrene. As the fraction from which the hydro- 
chloride was prepared was strongly lzvorotatory, the occurrence of /-sylvestrene in 
an essential oil was rendered highly probable for the first time by this investigation. 
But as More’s research was only carried on with very small quantities of material, — 
which did not permit of an exhaustive identification of the terpene said to be sylvestrene, | 
it remained desirable to confirm his results.
