Oligosaccharidesfrom the linkage-region tetrasaccharide, beta-D-GlcpA-(1----3)-beta-D-Galp-(1----3)-beta-D-Galp-(1----4)-D- Xylp, of chondroitin4-sulphate were isolated after trifluoroacetolysis. The oligosaccharides were purified by ion-exchange chromatography and paper chromatography and subjected to sugar and methylation analysis and g.l.c.-m.s. The recovery of linkage-region oligosaccharides
