黑木耳多糖在黑木耳子实体中是一种非常关键的物质,它除拥有一般物质的生化性质外,还有着一些能够调节免疫、抑菌、抗肝炎、抗突变、抗溃疡、降血糖、降血脂和促进血清蛋白生物合成等其他对人体有用的功效。文中以广西特产的黑木耳子实体为试验材料,经过热水的煮提和乙醇的沉淀之后得到水溶性质的粗多糖,通过使用气相色谱的测定,得到粗多糖组成为,甘露糖、葡萄糖醛酸、半乳糖、木糖、葡萄糖。

Auricularia auricular polysaccharide(AAP) is a key bio-active material.It has the general biological properties,but it also has the function of adjusting immunity,bacteriostatic,anti-hepatitis,inhibiting mutation,anti-ulcer,reducing blood sugar,reducing cholesterol,promoting serum protein biosynthesis,etc..Farm raised black fungus in Guangxi Province was used as raw material.The composition of black fungus was measured by the gas chromatography.The water-soluble qualitative coarse polysaccharide was extracted by hot water and ethanol.Gas chromatography showed the composition of coarse polysaccharide was several monosaccharides including mannose,glucuronic acid,and galactose,xylose,glucose.
