authors have termed evodiamine. On heating with alcoholic potash it
yields a base C 1 1H 10 N 2 and methyl-anthranilic acid. Its formula is
stated to be C 19 H 17 N 3 O.
In reference to the name " evodene," it should be mentioned that
Semmler and Schorsberger had previously used the same name for a
terpene which they isolated from the oil of Xanthoxylum aubertia.
OLL OF TODDALIA.
Toddalia aculeata (Toddalia asiatica) is a tree growing wild in the
Nilgiri mountains, and is also found in the Philippine Islands. It is
known as the wild orange tree. The leaves yield O08 per cent, of es-
sential oil, which, according to Brooks,^1 has an odour of camphor and
lemon-grass. Its characters are as follows :—
30°
Specific gravity 0-9059 at —
Refractive index 1-4620 „ 30°
It contains linalol to a considerable extent, and about 18 per cent,
of a substance resembling camphor and melting at 97°.OIL OF PELEA MADAGASCARICA.
The leaves and fruits of Pelea Madagascar'ica, a Malagasy shrub,
yield about 4 to 5 per cent, of essential oil having a powerful aniseed
odour.- It is yellow in colour and has the following characters:—
Specific gravity 0*953
Optical rotation.....,..+ 32° 22'
Refractive index 1'51469
It contains anisic aldehyde, but not much anethol, since it does not
congeal even at - 18°.OIL OF CLAUSENA ANISUM-OLENS.
The leaves of Clausena Anisum-olens, a plant growing in the Philip-
pines, yield about 1-2 per cent, of an essential oil having a powerful odour
of Eussian aniseed oil. The oil has been examined by Brooks,^2 who
found it to have the following characters :—
30°
Specific gravity at — 0 963
oO
Optical rotation 0°
Refractive index at 30° 1-5235
Saponification value 3-6
The oil contains 90 to 95 per cent, of methyl-chavicol.
ZYGOPHYLLACEyE,GUAIACUM WOOD OIL.This oil is identical with that which used to be offered in commerce
under the name of champaca wood oil. As a matter of fact neither name
can be regarded as correct. The wood from which the oil is distilled was
formerly believed to be that known as Palo balsamo or guaiacum wood.
It was originally believed to be the product of Guaiacum officinale, but it
is now clearly settled that it is the product of Bulnesia sarmienti, and is(^1) Philipp. Jour. Sc. (6), 333. (^2) /^^ 6 (ign), 344.
