veratrine defined in 1909 year

veratrine - Veratrine;
veratrine - Veratrine is easily exhausted from the seeds of Veratrum Sabadilla, by the following process:

The crushed seeds are exhausted with a 2 to 3 per cent, solution of oxalic acid for 24 hours, when a clear liquid is afforded, and is neutralised by ammonia. After about ½ hour, a precipitate is formed in the liquid; this is separated by filtration, and dissolved in pure cold alcohol. The alcoholic tincture, on evaporation, yields vetratine that is sufficiently white and crystalline. It is obtained perfectly so by dissolving in ether, without using any decolorising material.
