The Analyst, 1937
The article on ergot in this Handbook (vol. II, 2, pp. 1297–1354) was written by Arthur Cushny in 1914 but not published until 1924, without further revision. Thus a gap of more than two decades has now to be filled. In this interval the number of known ergot alkaloids has increased from two to eleven or twelve, all crystalline, and a considerable ...

Biogenetic interrelationships of ergot alkaloids
Archives of Biochemistry and Biophysics, 1961Abstract The biogenetic interconversions of clavine alkaloids have been studied by the use of clavine-C14 and clavine-H3 alkaloids labeled biosynthetically in saprophytic culture, and four different ergot strains in saprophytic cultures. Agroclavine was shown to be oxidized irreversibly to elymoclavine. The attack appears to be directly on the methyl
