| 摘 要： | 蔗渣含88．3％（干基）的膳食纤维，是一种良好的膳食纤维新资源。本文利用简化的CNDF法从蔗渣中提取出纯净的细胞壁物质（膳食纤维），分析其单糖组成为4．08％Ara，36．54％Xy1，31．68％Glc和3．29％UA。通过80℃H2O，NaClO2—HOAc，1mol／LNaOH和4mol／LNaOH4种溶剂将细胞壁物质分级成7种聚合物组分，并分析它们的单糖组成。

| Abstract: | Bagasse contains 88. 3% (db. ) 0f dietary fibre, which is a good new resourceof dietary fibre. The pure cell wall material (CWM) or dietary fibre was isolated frombakasse by the simplifiedCNDF method, whose mon0sugar compositions were 4. 08% arabi-n0se, 36. 54% xylose, 31. 68% glucose and 3. 29% uronic acid. Seven polymeric fractionswere further fractionated from pure CWM, with the successive extractions of 8OC H,O l Na-ClO,-HOAc, 1mol/L NaOH and 4mol/L NaOH. The monosugar compsitions of such sevenfractions were all analysed. |
