142 THE CHEMISTEY OF ESSENTIAL OILS
The so-called Culilavan oil is obtained from the bark of Cinna-
mortmm Culilawan, which yields about 4 per cent, of oil. This has a
specific gravity T050 to 1*055. It contains about 60 per cent, of
eugenol, together with some methyl-eugenol and terpineol. It is
soluble in 3 volumes of 70 per cent, alcohol.
The bark of Cinnamomum Kiamis yields about 0*5 per cent, of a
deep golden essential oil having an odour resembling, but less delicate
than, ordinary cinnamon bark oil. It has the following characters:—
Specific gravity 1-0198
Optical rotation ....
Refractive index1-58
Aldehydes
It is soluble in 1 volume of 80 per- 1° 50'
1-5828
80 per cent, (bisulphite method)
cent, alcohol. It contains about
11 per cent, of phenols (eugenol).
The bark of Cinnamomum oliveri, the so-called Brisbane " White
Sassafras " tree, yields from 1 per cent, to 24 per cent, of essential oil.
This has been examined by Hargreaves.

The plant is a handsome tree with grey rough bark, growing in the
scrubs on the North Coast Eailway, Queensland. When distilled in a
current of steam the bark yielded approximately 24 per cent, of oil,
having a specific gravity of 1*030 and refractive index 1-5165 at 23°.
On fractionation it was found to contain pinene (12 to 15 per cent.),
^-camphor (18 to 20 per cent.), safrol (25 to 27 per cent.), and eugenyl
methyl ether (40 to 45 per cent.). The oil from the leaves contained
about 25 per cent, of a mixture of terpenes, one of which was identified
as pinene, and the other, which formed a nitrosite melting at 103°, was
probably phellandrene. The leaf oil contained about 60 per cent, of
5-camphor and 15 per cent, of phenols and other substances. The
phenol gave a green coloration with ferric chloride in alcohol, and had
the formula C 10 H 15 O 2. No safrol was present, and the author could
not detect the presence of eugenol, cinnamic aldehyde nor cineol,
which had been previously suspected by Baker and Smith.
It contains cineol, eugenol, and cinnamic aldehyde, but the principal
constituent is probably safrol.
The bark of Cinnamomum peditinervium, a tree indigenous to the
Fiji Islands, yields about 1 per cent, of oil, having the following char-
acters :—
Optical rotation..- 5°
Refractive index 1-4963
Saponification value.. ... .44
„ „ (after acetylation) 115'8
The principal constituent is safrol, but linalol, eugenol, and eugenol-
methyl ether are also present in the oil.
The leaves of Cinnamomum Tamala, a South-Asiatic tree, yield an
•essential oil having the following characters :—
Specific gravity ......... 1*0257
Optical rotation + 16° 37'
Refractive index 1-5259
Phenols 78 per cent.
It is soluble in 1 to 2 volumes of 70 per cent, alcohol. The oil con-
sists chiefly of eugenol, together with phellandrene and a little camphor.
