coniine  毒芹碱      (in Enlgish and Chinese 中英文)

 Compiled by: Joe Hing Kwok Chu

Coniine is the main alkaloid toxin in poison hemlock (Conium maculatum). It is a colorless, oily liquid alkaline. It was first isolated in 1827 by Giesecke. In 1895 Wolffenstein determined structure. Hemlock and its salt  are extremely poisonous. It is toxic to humans and all classes of livestock; less than 0.2g is fatal to humans, with death caused by respiratory paralysis, but when used in a small amount it has an physiological anticonvulsant effect.

毒芹鹼為毒參（Conium maculatum）主要生物鹼毒素。它是一種無色鹼性油狀液體。 於1827 年，Giesecke 將其首次分出。 於1895年，Wolffenstein 確定其分子式之結構。

毒芹及其鹽是極毒的。小於0.2克的毒芹鹼是對對人類和家畜可致命。它能引起呼吸麻痺死亡，但在少量使用時，它有一個生理抗驚厥作用。
