用真菌酶制剂Driselase水解竹笋细胞壁，得到一种二阿魏酰阿拉伯木聚糖六糖。 根据n.m.r.，确定二阿魏酰低聚糖的结构为5，5 '-二-O-（二阿魏-9，9'-二酰基）-[α-L-阿拉伯呋喃糖基-（1 -> 3）-O-β-D-吡喃木糖基-（1 -> 4）-D-吡喃木糖]。光谱、甲基化分析和快速原子轰击质谱（f.a.b.- m.s.）。 这是首次报道的阿拉伯聚糖通过二阿魏酸共价交联的证据。
Hydrolysis of bamboo shoot cell-walls with Driselase (a fungal enzyme preparation) released a diferuloyl arabinoxylan hexasaccharide. The structure of the diferuloyl oligosaccharide was determined to be 5,5'-di-O-(diferul-9,9'-dioyl)-[alpha-L-arabinofuranosyl-(1 --> 3)-O-beta-D-xylopyranosyl-(1 --> 4)-D-xylopyranose] on the basis of n.m.r. spectroscopy, methylation analysis, and fast-atom-bombardment mass spectrometry (f.a.b.-m.s.). This is the first reported evidence that arabinoxylans are covalently cross-linked via diferulic acid.
