Structural studies on the galactomannans of lichens of the genus Cladonia -
Lichenologist,
29(5): 471-481
Galactomannans were isolated from Cladonia signata, C. furcata, C. imperialis, and C. clathrata via successive alkaline extraction and precipitation with Fehling solution and Cetavlon. They were investigated using ⊃13C-NMR spectroscopy, methylation analysis, and Smith degradation, and their specific rotations and monosaccharide compositions determined. As with galactomannans of other Cladonia species, they contained (l →6)-linked main chains of α-mannopyranose, which were non-substituted (structure …
