Detection of Alkaloids and Some Ill-Defined Organic SubstancesL
A general method for effecting the detection of alkaloids was first proposed by Stas. Since the publication of this method, modifications to it have been recommended by Otto, and by L. Uslar and J. Erdman. Other processes have been suggested by Rodgers and Girwood, by E. Prollius, and by Graham and Hofman. The latter will doubtless become general in their application; but up to the present time they have been employed exclusively in the detection of strychnine. Dialysis has also been recently applied in the separation of alkaloids.
