W. R. Dunstan and F. W. Short discovered (1884) a new 
glucoside in the pulp of the fruit of Strychnos Nux-vomica to 
the extent of 4 to 5 per cent., and named it Loganin. This

also shown that loganin is present in small quantity in the 
seeds and in prep: wrations made from them. (Pharm. Journ. 
Fes) XIV., 1025.) 
_ In nine samples of nux-vomica seeds examined by Beckurts, 
the percentage of total alkaloids ranged from 1°53 to 3°42 
per cent. The same chemist found the percentage of strych- 
ine in ten determinations to vary between 2°17 and 2°38 per 
cent. (Archiv. der Pharm., 1890, 330-347.) W. R. Dunstan 
and F. W. Short ina mui of seeds from Ceylon found as 
ch as 5-34 per cent, of totalalkaloids. They found the pulp 
the fruit to contain 1:4 per cent. of strychnine and 1 per 
cent. of brucine. (Pharm. Journ. [3], XIV and XV.)
