摘要
从凤尾菇子实体提取水溶性多糖粗品A ,经分离纯化 ,得到多糖纯品B、C两个组分。B、C的平均分子量为18 9× 10 4、 4 5 1× 10 4。用HPLC色谱、IR色谱测定其结构 ,表明凤尾菇多糖B是由半乳糖、木糖、树胶醛糖等糖基组成的 ,摩尔比为半乳糖∶木糖∶树胶醛糖 =1 0∶0 74∶2 0 93。
The water-soluble raw polysaccharide A was obtained from the Pleurotus Sajor-caju(Fr.)Singer.The pure polysaccharide B and C were got from the water-soluble raw polysaccharide A by separation、purification B and C average molecular weight is 18 9×10 4 and 45 1×10 4 respectively.The determination of the structure by HPLC and IR spectra,the polysaccharide B of the Pleurotus Sajor-caju(Fr.)Singer is composed of galactose,xylose and arabinose,the molar rations:Gal∶Xyl∶Ara=1 0∶0 74∶20 93.
