Glycosyl residue compositions of the RG-II isolated from lycophyte, pteridophyte, gymnosperm, and angiopserm cell walls

RG-II was isolated by SEC from the material solubilized from the walls of lycophytes and pteridophytes by treatment with EPG. The glycosyl residue compositions were determined by GC/EI-MS analysis of the alditol acetates.
