Frankforter : the alkaloids of veratkum. 1037 



which occurred between 110-114 was due to the liberation of 

 iodine. 



An analysis of the substance dried at 100° to constant weight 

 was made with the following results: 

 .2231 grms. of dried iodide gave .2834 grms. C0 2 and .0912 Ho O

Veratrine triiodide C32 H49 NO9 I3. The red iodide dried 

 at 110" to constant weight became a dark brown amorphous 

 powder which showed no signs of crystallization on treating 

 with water, It is insoluble in ether and much less soluble in 

 methyl and ethyl alcohol than the tetraiodide. It melts at 

 136°-138°. 



Analyses gave the following results: 

 I. .2034 grams of sub. gave .2938 grms. COo and .1152 H 2 O. 

 II. 



While it was evident that more than one-fourth of the iodine 

 could be driven off by drying, repeated attempts to obtain the 

 diiodide were unsuccessful. 



Veratrine monoiodide C-.n H& NOo I- By treating the tetra- 

 iodide with dilute ammonia and allowing to stand for several 

 hours in a warm place, the bright red color disappeared and a 

 light yellow granular substance was formed. It proved to be 

 insoluble in water, ether and chloroform, but very soluble in 

 methyl and ethyl alcohols. A bright yellow powder is formed 

 on evaporating off the alcohol. It does not form the waxy 

 mass which characterizes the tetraiodide. It was obtained 

 from a dilute alcoholic solution as a fine crystalline powder 

 with a melting point of 212°-214°. It contains two molecules 

 of water which were removed by drying at 100°.
