1906Barger & Carr in Chem. News XCIV. 89/2 The crystalline alkaloid ergotinine was obtained from ergot by Tanret more than thirty years ago... We have now obtained the second alkaloid in a state of chemical purity, and suggest for it the name ergotoxine. 1937Gwynne-Vaughan & Barnes Fungi (ed. 2) 253 Owing to the presence of ergotoxine the sclerotia, if included in the grain used for bread, give rise to serious disease. 1952L. Marion in Manske & Holmes Alkaloids II. 377 This anomaly..has recently been explained away by the discovery that ergotoxine is not homogeneous, but a complex mixture. 1958Fruton & Simmonds Gen.
