采用核磁共振波谱分析技术，利用核磁共振碳谱、核磁共振氢谱和二维（2D）核磁共振，通过样品与木二糖、木三糖、木四糖、木五糖、木六糖标准品的图谱对比分析，确定低聚木糖混合物中各组分的1H和13C的准确归属。结果表明，木聚糖糖苷键数量越多，中间糖的共振峰强度会越大。低聚木糖样品中主要成分为木二糖、木三糖等糖链很短的低聚糖。

Two configurations of Xylo-oligosaccharide(XOS)standards and sample are determined by NMR when dissolved in heavy water,their main characteristic peaks in the1H-NMR and13C-NMR spectrum are attributed. The results indicate that with more glycosidic bonds number of XOS,the strength of the formant will be greater,the main component of XOS samples is Xylobiose and Xylotriose.
