Hankey, 'William T., believes that 1.75 per cent of ipecac alkaloids 
is a fair standard for average ipecac. He prefers iodeosin as an in- 
dicator. — Am. Druggist, X. Y., 1906, v. 49, p. 361. 
Puckner, W. A., reviews some of the recent literature relating to 
the assay of ipecac and records Fromme's method in detail. — Pharm. 
Rev., Milwaukee, 1906. v. 24. in 268. 
Gordin. H. M.. outlines a method for the assay of ipecac root, using 
a mixture of ether three volume parts and chloroform one volume part 
to exhaust the drug after treating with a solution of sodium car- 
bonate. — Proc. Am. Pharm. Ass., 1906, v. 54. p. 378. 
Dohme, A. R. L.. reports that seven analysts working with the 
same sample of fluid extract of ipecac, by the same process, found 
from 1.53 to 1.80 per cent of alkaloid. — Am. Druggist. X. Y., 1906, 
v. 49, p. 268. 
Kebler, L. F., presents the results of some cooperative work on 
the assay of ipecac, by seven analysts using three methods given in 
detail. The maximum variation reported was from 1.57 to 2.1 per 
cent of alkaloid. The results with the U. S. P., VIII, method varied 
from 1.62 to 1.99 per cent. — Proc. Off. Agric. Chem., 23d Ann. Conv., 
pp. 138-139. (Bull. Bur. Chem. U. S. Dept. Agric., 1907, Xo. 105.) 
Schiirhoff. P., reports finding powdered ipecac adulterated with 
dextrin from j^otato starch. He points out that in this adulteration 
the characteristic shape of the potato starch is readily detected ; being 
quite different from the compound starch grain normally present 
in ipecac. — Pharm. Ztg.. Berl., 1906. v. 51. p. 479. 
Yanclerkleed, Charles E., found a sample of ipecac marked prob- 
ably very high test." which assayed only 1.52 per cent, of ether solu- 
ble alkaloids; U. S. P. requires 2 per cent (now 1.75 per cent). — Proc. 
Pennsylvania Pharm. Ass., 1906, p. 123. 
Gane, E. H.. reports on one sample of Carthagena ipecac which was 
found to contain 1.85 per cent of alkaloids. Eight samples of Rio 
ipecac varied from 1.55 to 2.3 per cent of alkaloids. — Proc. Am. 
Pharm. Ass., 1906, v. 54. p. 338. 
Ohliger, Willard, reports that ipecac usually runs lower than the 
required standard. — Proc. Michigan Pharm. Ass., 1906, p. 48. 
Smith. Kline & French Co., report on the examination of 6 sam- 
ples of Carthagena ipecac root, which contained from 2 per cent to 
2.25 per cent total alkaloids. — Lab. Rep. S. Iv. & F., 1906, p. 17. 
Dieterich. Karl, reports examining 15 samples of Rio ipecac, of 
which only three complied with requirements of 2 or more per cent 
of alkaloids. — Helfenberger Annalen, 1905, 1906, v. 18, p. 125. 
Moerk, Frank X., points out that fluid extract of ipecac repre- 
sents but 87.5 per cent of the active constituents of ipecac. — Proc. 
Pennsylvania Pharm. Ass., 1906, p. 159.
