“Ergot Alkaloids”  

  In organic chemistry, Ergot Aalkaloids structurally can be divided into three groups: clavines, lysergic acid amides (ergoamines) and ergopeptides (ergopeptines), each sharing the first biosynthetic steps, leading to the formation of a tetracyclic ergoline ring system (except the simplest tricyclic compound chanoclavine).
  In biochemistry, Ergot Alkaloids are alkaloids originally isolated from the ergot fungus Claviceps purpurea (Hypocreaceae) include compounds that structurally related to ergoline and ergotamine. *
