The structures of elymoclavine-O-β-D-fructofuranoside {1] and a new ely-moclavine-0-β-D-fructofuranosyl-(2→l)-0-β-D-fructofuranoside [2} produced in saprophytic cultures of strains Claviceps sp. SD 58 and Claviceps purpurea 88 EP on sucrose medium are described. The structures have been determined on the basis of uv, ms, and 2D-nmr data and a degradation procedure. © 1989, American Chemical Society. All rights reserved.
