HYDRASTINA. 
” ! 
Riedel’s Berichte (Berl., 1906, p. 24) asserts that recrystallized 
hydrastine hydrochloride melts at 210-211° C. 
Herder, M., (Arch. d. Pharm., 244, No. 2, 1906, 120) in discussing 
the precipitation of alkaloids by calcium- and barium-mercuric 
iodides, asserts that when hydrastine is treated with the calcium salt 
in solutions of 1 : 2,000, and barium salt in solutions of 1 : 2.400, an 
immediate white, apparently crystalline precipitate is produced. —

HYDRASTIS. 
Henkel, Alice, mentions Hydrastis canadensis L., otherwise known 
as hydrastis, goldenseal, yellowroot, ground-raspberry, orangeroot. i 
and yellow puccoon, as being a native in rich soil in shady woods, 
southern Xew York to Minnesota, south to Georgia and Missouri, but 
principally in Ohio, Indiana, Kentucky, and West Virginia. — Bui. 
Bur. Plant Ind., U. S. Dept. Agric., 1906, Xo. 89, p. 37. 
Hus, Henri, discusses the cultivation of Hydrastis canadensis. He 
points out that the plant does best in rich woods and that the fruit 
should be gathered as soon as ripe, dried, and the seed planted. The 
literature relating to the germination of the seed is reviewed and a 
number of experiments, under varying conditions, are reported. — 
Rep. Missouri Bot. Gard., 1906, St. Louis, 1907. pp. 85-94. 
True, Rodney H., reports that the methods of hydrastis culture 
have been worked out fairly well and the department has published 
a bulletin on the subject. — Oil, Paint and Drug Rep., 1906, v. 70, 
Oct. 17, p. 37. 
Goris and Wallart present a comjlrehensive paper on the history, 
external morphology, geographic origin, description, anatomy, chem- 
ical composition, microehemic reactions, localization of the alkaloids, 
culture, methods of propagation, etc., of Hydrastis canadensis L. — 
Bui. des sc. pharm., Par., 1906, v. 13, pp. 624-633. 
Bar ford, P. C. Tang, discusses the history and composition of 
hydrastis and the variability found in commercial fluid extract of 
hydrastis. — Arch. f. Pharm. og Chem., Copenhagen, 1906, v. 13, 
pp. 218-223, 233-235. 
The Ph. Brit. Committee of Reference in Pharmacy believes that 
for hydrastis an ash limit is necessary. — Chem. & Drug., Lonch, 1906. 
v. 69, p. 863. 
Herder. M., discusses the behavior of the hydrastis alkaloids with 
various reagents and the demonstration, by microchemical means, of 
the situation of alkaloids. — Arch. d. Pharm., Berl., 1906, v. 244, 
p. 128.
