A new ribose trisaccharide, α-Ribf-(1→2)-α-Ribf-(1→3)-α-Ribf (1), was isolated together with 5-O-(α-mannosyl)-myo-inositol (2), 2-O-(α-mannosyl)-myo-inositol (3), trehalose (4), and  d-ribulose (5) from a submerged cultivation of Streptomyces coelicolor A3(2). The structures of these compounds were elucidated by spectroscopic and chemical methods. Concentrations of these compounds in the medium were in the range from 0.04 (1) to 0.5 (4) mg/mL.
