Note on Oleoresina Cubebae. 
Am. Jonrn. Pharm., 38, p. 210. [Pharm. Journ., 25, p. 620.] 
The author reports the results obtained in the extraction of cubebs with 
ether, alcohol and benzine. The yield of oleoresin obtained was as fol¬ 
lows: ether, 21.9 per cent., alcohol, 27 per cent., benzine, 16.5 per cent, 
(p. 212). The use of benzine in the preparation of this oleoresin is 
not recommended as it does not extract the eubebin completely.

On Substitutes for Ether and Alcohol in the Preparation 
of the Official Oleoresins. 
Proc. A. Ph. A., 14, p. 208. [Am. Journ. Pharm., 38, p. 24.] 
The feasibility of displacing the ether remaining in the exhausted drug 
with benzine, glycerine or water is discussed. From experiments conducted 
along this line, it was concluded that benzine would be the most preferable 
for this purpose. A working formula in which benzine is used to this 
end is described. Cubebs and ginger were the drugs employed in the 
experiments.

The extract is directed to be prepared by treating the powdered drug 
successively with water, alcohol and ether. The extract so prepared is 
said to contain all of the medicinal principles of the original drug.

On the preparation of Oleoresins with benzine. 
Proc. A. Ph. A., 15, p. 94. 
One pound of cubebs percolated with 2 pounds of light benzine, specific 
gravity 86°, Beaume, is stated to have yielded a trifle over 5 per cent, of 
oleoresin of a pale ash color. 
It is further stated that neither benzine nor ether completely exhaust 
ginger, but that alcohol is a much better solvent for this purpose. 
Heydenreich, F. V. 1868 
On Cubebin and the Diuretic Principle of Cubebs. 
Am. Journ. Pharm., 40, p. 42. 
Eighty ounces of cubebs yielded, when extracted with ether, 19 ounces 
of oleoresin or nearly 24 per cent. 
The results obtained in the administration of cubebin, the volatile oil 
and the soft resin are given.
