An editorial discusses the outlook for senega root and presents a 
table giving high and low quotations for this drug during the past 
five years. — Oil, Paint & Drug Reporter. 1906. v. 69, June 4, p. T. 
(See also Aug. 27, p. 7.) 
Lyons, A. B., thinks that the retail druggist will probably find the 
now official fluid extract of senega to keep better than the preparation 
of the U. S. P.. 1890. which contained ammonia water. — Proc. Am. 
Pharm. Ass., 1906. v. 54, p. 443. 
Francis, John AL, commends the change from 50 c. c. volatile alkali, 
ammonia, to 30 c. c. potassium hydroxide to prevent gelatinization. — 
Bull. Pharm., Detroit. 1906, v. 20, p. 12. 
Caldwell, Paul, recommends that 5 per cent of alcohol and the same 
amount of glycerin be added in making sirup of senega. He also 
recommends the use of magnesium carbonate as a clarifying agent. — 
Drug. Circ. & Chem. Gaz., X. Y., 1906, v. 50. p. 159. 
SENNA. 
Gehe & Co. point out that the imports of Tinnevelly senna into 
London amounted to 8.028 bales, against 6.731 bales in 1904 and 4,524 
bales in 1903. The export of Alexandria senna from Hodeida, 
Arabia, is given as being 828 bales in 1904. 419 bales in 1903, 717 
bales in 1902. and 644 bales in 1901. — Handels.-Ber., Gehe & Co., 1906, 
p. 28. 
The Ph. Brit. Committee of Reference in Pharmacy report on 
senna savs the ash should be almost entirely soluble in hvdrochloric 
acid, and microscopical characters should be indicated. — Chem. and 
Drug., Lond., 1906, v. 69. p. 864. 
Philipp Roder. TCien, reports examining eight samples of senna, 
which varied from 3.97 to 11.54 per cent of ash. The amount of ex- 
tractive soluble in 90 per cent alcohol varied from 3.22 to 14.82 per 
cent. — Pharm. Post, TCien, 1906, v. 39. p. 264. 
Dieterich. Ivarl. reports on four samples of Alexandria senna, 
which yielded from 25.90 to 32.62 per cent of dry aqueous extract. — 
Helfenberger Annalen, 1905. Berl., 1906, v. 18. p. 110. 
Mitlacher, TCilhelm. asserts that oxymethylanthraquinones are 
readily demonstrated to be present in senna, by sublimation and sub- 
sequently dissolving the sublimed material in solution of potassium 
hydroxide. — Pharm. Prax., 1906. v. 5, p. 435. 
Francis, John TL, thinks that both time and alcohol will be saved 
by putting the drug in a strong cloth, wringing or squeezing out the 
excess of alcohol thoroughly and then proceeding with the percola- 
tion as usual without preliminary drying. A 30 per cent alcoholic 
menstruum would have been found as satisfactory as the diluted 
alcohol prescribed. — Bull. Pharm., Detroit. 1906, v. 20, p. 12.
