Structure of the carbohydrate moiety of the eremomycin molecule was assessed. Two residues of eremosamine were detected in the antibiotic. One of them in the composition of 2-0-(L-eremosaminyl)-D-glucopyrazone dissaccharide was linked by the phenol group to monodechlorvancomycinic acid and the other formed the monosaccharide branch by the alcohol group of the same acid at the peptide C-end area. On the basis of the results of the present study and the data published earlier (structure of the aglycone and aminosugar) the structure of eremomycin was assigned.
