Dieterich, Karl, reports examining a number of samples of extract 
of nux vomica which were found to contain from 21.44 to 28.58 per 
cent of moisture, from 1.10 to 1.45 per cent of ash, and from 15.52 
to 20.16 per cent of total alkaloids. — Helfenberger Annalen, 1905, 
1906, v. 18, p. 163. 
Philipp Roder, Wien, outlines a method for the estimation of total 
alkaloids in extract of nux vomica, and reports an examination of five 
samples which varied from 13.13 to 16.02 per cent of total alkaloids. — 
Pharm. Post, Wien, 1906, v. 39, p. 263. 
Moerk, Frank X., asserts that the statements on page 571 [XJ. S. 
P. VIII], referring to fluid extract of nux vomica, do not correspond 
with the statement in the text of the pharmacopoeia itself. — Proc. 
Pennsylvania Pharm. Ass., 1906, p. 160. 
Lyons, A. B., calls attention to the fact that the standard for fluid 
extract of nux vomica is very low in comparison with that of the 
drug, but approves it, nevertheless, considering the difficulty in 
completely exhausting the drug. He reports that 11 of the 12 replies 
received indicated that the U. S. P. standard for fluid extract of 
nux vomica is satisfactory and readily maintained. — Proc. Am. 
Pharm. Ass., 1906, v. 54, pp. 437—140. 
The Ph. Brit. Committee of Reference in Pharmacy report on 
liquid extract of nux vomica recommends modification of the process 
to insure absence of fat. Revise assay process. — Cliem. & Drug., 
Lond., 1906, v. 69, p. 863. 
England, Joseph W., discusses the tincture of nux vomica of the 
U. S. P. VIII, compares the official preparation with the similar 
preparation formerly official, and suggests that tincture of nux 
vomica be directed to be made from an assayed powdered fat-free 
nux vomica. — Proc. Am. Pharm. Ass., 1906, v. 54, pp. 428—130. 
Eberle, E. G., asserts that tincture of nux vomica should be made 
from the fluid extract, if not made from the drug. — Ibid., v. 54, p.450. 
Lyons, A. B., suggests preparing the U. S. P. tincture from the fluid 
extract of nux vomica. — Ibid ., v. 54, p. 430. 
Hill, J. Rutherford, in discussing a paper by Farr and Wright, 
pointed out that Dey in a paper read at Edinburgh showed that nux 
vomica powder could be easily and completely exhausted of alkaloids 
by simple percolation, and he suggested that such a tincture might be 
introduced into the British Pharmacopoeia. — Year Book of Pharmacy, 
1906, p. 241. 
Philipp Roder, Wien, outlines a method of assay for tincture of 
nux vomica, similar to that suggested for extract of belladonna, and 
reports examining five samples of the tincture which varied from 
0.200 to 0.261 per cent of total alkaloid. The Ph. Austr. VIII 
requires '0.25 per cent of alkaloid. — Pharm. Post, Wien, 1906, v. 39, 
p. 298.
