南海海洋红树林真菌2560号多糖A2的研究

The Polysaccharide A2 from the Marine Mangrove Endophytic Fungus No. 2560 from the South China Sea

从南海海洋红树林真菌2560号真菌的菌体中提取到多糖A2,通过完全酸水解、糖腈乙酸酯衍生化以及GC MS研究分析表明,A2多糖由岩藻糖、木糖、甘露糖、葡萄糖以及半乳糖组成,摩尔比为2∶2∶17∶5∶2。

A polysaccharide A2 from mangrove endophytic fungus No.2560 from the South China Sea was isolated. Analyses by complete acid hydrolysis and aldoononitrile acetate derivatives and GC/MS indicated that it was composed of L-fucose, D-xylose, D-mannose, D-glucose,and D-galatcose with molar ratio of 2∶2∶17∶5∶2.
