Amanitin

Title: Amanitin
CAS Registry Number: 11030-71-0
Literature References: Group 1 mushroom toxin from the poisonous mushroom Amanita phalloides (Fr.) Secr., Agaricaceae. Inhibits protein synthesis of mammalian cells. Comprised of a-, b-, g-amanitin and amanin. a-Amanitin is the major poisonous constituent of A. phalloides; it is 10-20 times more toxic than phalloidin, q.v.
