摘要：

A xyloglucan was isolated from the 24% KOH extract of gobo (edible burdock, Arctium lappa L.). A methylation analysis and enzymic degradation studies on the polysaccharide showed that gobo-xyloglucan was built up predominantly of repeating-oligosaccharide units of hepta-(Glc:Xyl=4:3), nona-(Glc:Xyl:Gal: Fuc=4:3:1:1) and deca-(Glc:Xyl:Cal:Fuc=4:3:2:1) saccharides in an approximate molar ratio of 14: 12:5, which are the typical structural units of dicot xyloglucans.
