  Partial acetolysis of Bletilla-glucomannan, the mucilage from the tubers of Bletilla striata REICHENBACH fil., has led to the isolations of fourteen oligosaccharides. Analysis of components, methylation and partial degradation studies provided the evidences that they are O-β-D-mannopyranosyl-(1→4)-D-mannopyranose, O-α-D-mannopyranosyl-(1→4)-D-mannopyranose, O-β-D-mannopyranosyl-(1→4)-D-glucopyranose, O-β-D-glucopyranosyl-(1→4)-D-mannopyranose, O-β-D-glucopyranosyl-(1→4)-D-glucopyranose, O-β-D-mannopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-D-mannopyranose, O-β-D-glucopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-D-mannopyranose, O-β-D-mannopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-D-glucopyranose, O-β-D-mannopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-D-glucopyranose, O-β-D-mannopyranosyl-(1→4)-O-β-D-glucopyranosyl-(1→4)-D-mannopyranose, O-β-D-glucopyranosyl-O-β-D-glucopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-D-mannopyranose, O-β-D-mannopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-D-mannopyranose, O-β-D-glucopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-D-mannopyranose, and O-β-D-mannopyranosyl-(1→4)-O-β-D-glucopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-D-mannopyranose. Among them, it is conceivable that mannobiose having α-glycosidic linkage is the artifact produced during the reaction.

  Takahashi R, Kusakabe I, Kusama S, Sakurai Y, Murakami K, Maekawa A, Suzuki T "Studies on the mannanase of Streptomyces. Part IV. Structures of glucomanno-oligosaccharides from the hydrolytic products of konjac glucomannan produced by a β-mannanase from Streptomyces sp" - Agricultural and Biological Chemistry 48 (1984) 2943-2950
  

  The hydrolysis of konjac glucomannan by a purified extracellular mannanase from Streptomyces sp. produced four kinds of oligosaccharides containing both glucose and mannose residues. These glucomanno-oligosaccharides were identified as O-β-D-glucopyranosyl-(1→4)-D-mannopyranose (epicellobiose, G1M1-I), O-β-D-glucopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-D-mannopyranose (G2M1-I), O-β-glucopyranosyl-(1→4)-O-β-D-glucopyranosyl-(1→4)-D-mannopyranose (G2M1-I) and O-β-D-glucopyranosyl-(1→4)-O-β-D-glucopyranosyl-(1→4)-O-β-D-mannopyranosyl-(1→4)-D-mannopyranose (G2M2-I). On the basis of the structure of the above oligosaccharides, the mode of action of the mannanase on the glucomannan is discussed.

  The main component of the mucilage in the bulbs of Suisen (Narcissus tazetta L., var. chinensis Roem) has been shown to be a glucomannan composed of D-glucose and D-mannose in the ratio of 2:3 and having a relatively low degree of branching. Acetolysis of the polysaccharide led to the isolation of β-(1→4)-β-(1→3)-linked oligosaccharides composed of D-mannose and/or D-glucose residues. The average chain length (c.1.) of the polysaccharide was determined by methylation analysis to be about 22.
