Forty-eight lots of capsicum were examined. The yield of ether-soluble 
oleoresin, when the latter was dried for one hour on a water bath, was 
found to vary from 11 to 26 per cent., the average 18 per cent, (p.891.)

It is stated that a good sample of cubebs should yield 20 per cent, of 
ether-soluble extract.

Aspidium is stated to be one of the most useful of drugs when carefully 
collected and preserved, but that much of the rhizome is inert and is ob¬ 
tained from any old species of fern. It is said to be falling into disuse 
on this account. It is thought that the observance of more care in the 
collection of the drug and the preparation of the oleoresin would restore 
its popularity as an anthelmintic.

Some suggested standards and changes, for the U. S. P. 
Am. Journ. Pharm., 82, p. 21. 
The author asserts that a test for capsicum should be included, in the 
U. S. P. requirements for the oleoresin of ginger as many commercial 
samples used in making ginger ale extracts contain oleoresin of capsicum 
and these occasionally find their way into the pharmaceutical trade. 
A method for the detection of capsicum in the oleoresin of ginger based 
on the neutralization of the pungent principle of the ginger with potassium 
hydroxide is described (p. 25.)

Seven samples of capsicum yielded from 15.10 to 22.27 per cent, of 
oleoresin; one sample of African ginger 10.12 per cent; two samples of 
Jamaica ginger 5.636 and 6.316 per cent., respectively (p. 147.)
