Abstract: In the title compound, C₃₀H₃₃N₃O₉S, the glucoside moiety is attached to the pyridone via the S atom. The expected absolute configuration was confirmed. Dimensions at sulfur are S-C(pyridone) 1.780  (2), S-C(glucoside) 1.803  (2)  Å, C-S-C 98.15  (11)°. There are three short HO contacts (<2.5  Å) that determine the molecular packing.
