\Co"nine\ (? or ?), n. [From {Conium}.] (Chem.)
A powerful and very poisonous vegetable alkaloid found in the
hemlock ({Conium maculatum}) and extracted as a colorless
oil, {C8H17N}, of strong repulsive odor and acrid taste. It
is regarded as a derivative of piperidine and likewise of one
of the collidines. It occasions a gradual paralysis of the
motor nerves. Called also {coniine}, {coneine}, {conia}, etc.
