Contine (konein)

( Chem.) This alkaloid, noticed in SECTION I of this work under its other spelling, conine, has been artificially prepared by Laden burg by heating alcohol and ammonia at 210°, together with butyraldehyde, precipitating with platinum salt, and distilling the product. The artificial alkaloid is entirely similar in its reaction and physical properties to the native, and po e es like poisonous qualities. C. (also known as conine, conicine, and cicutine) is an oil of disagreeable odor, extracted from the water-hemlock. It is violent in its poisonous action, producing paralysis of the motor nerves. It is closely related chemically to piper idine, an alkaloid obtained from pepper, which in its turn closely approaches pyridine, a substance obtained from bones through heating.
