摘　　要：利用黑木耳提取多糖后的料渣(主要为胶质物质),与铁(Ⅲ)合成黑木耳胶质铁配合物(AGIC),并测定AGIC的理化性质。结果表明AGIC为无定形棕色粉末,易溶于水,其水溶液中不存在游离的铁(Ⅲ),表明铁(Ⅲ)与黑木耳胶质形成了稳定的配合物。采用抗坏血酸还原,AGIC中的铁(Ⅲ)易被抗坏血酸还原成铁(Ⅱ),说明黑木耳胶质铁配合物有望开发成理想的口服补铁剂。Auricularia auricula colloid-Fe complex （AGIC） was synthesized by Auricularia auricula colloid and FeCl3, and its physicochemical property was determined. It was showed that AGIC was a kind of brownish and shapeless powder, and was able to dissolve in water and its solution assumed neutral properties. AGIC was very stable and could be reduced to Fe （Ⅱ） by aseorbic acid. AGIC would be expected to become an ideal iron-supplementary nutrition.
