title: Structural analysis of antiviral sulfated alpha-D-(1-->3)-linked mannans.
abstract: The structures of two alpha-(1-->3)-alpha-D-xylo-mannans were determined. The different antiviral activity of the xylo-mannans from Nothogenia fastigiata was explained on the basis of a flexible backbone, molecular size, content and distribution of sulfate groups and of the single stubs of beta-(1-->2)-linked D-xylose.
