1906 Barger & Carr in Chem. News 94 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.

1937 H. Gwynne-Vaughan & B. F. Barnes Struct. & Devel. 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.

1952 L. 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.

1958 J. S. Fruton & S. Simmonds Gen. Biochem. (ed. 2) xxxiii. 862 Ergot contains the pharmacologically active alkaloids ergometrine, ergotamine, and several ergotoxines.
