摘　　要：测得竹荪多糖 DNI由木糖、甘露糖、葡萄糖组成 ,摩尔比为木糖 :甘露糖 :葡萄糖 =0 .88:1∶ 0 .2 8。与文献 [1～ 3]相比是一种未见报导的新多糖。红外光谱证明为β型糖苷键连结 ,经高碘酸氧化 ,Smith降解后 ,用高效液相色谱 ( HPLC) ,毛细管电泳分析 ,证明 DNI是以β( 1→ 3)连接的甘露糖残基为主链骨干 ,并具有少量β( 1→ 6 )的侧链和边缘结构。s:Its been determined that Polysaccharide DNI is composed of xylose,mannose and glucose.The mole ratio is xylose,mannose and glucose=0.88:1:0.28.Comparied with the existing document,it has never been reported.D.I.Fish polysaccharide DNI was conducted by using analytical techniques such as IR;HPLE and CE.It has been found that DNI is composed of a main chain of β(1→3)-D-ploymer of mannose and glucose,with a little amount of β(1→6)side chains and side structure.
