摘要
目的比较黑木耳可溶性多糖与胶质类物质(不溶性多糖)的化学组成,及与铁(Ⅲ)配合生成铁复合物的能力与性质。方法以干制黑木耳为原料进行水提,制备并分析黑木耳可溶性与不溶性多糖的组成,然后在碱性条件下,分别使它们与三氯化铁作用合成黑木耳多糖铁(APIC)与胶质铁复合物(AGIC),并比较它们的性质。结果黑木耳胶质与铁(Ⅲ)形成的复合物更稳定,其复合物中的铁(Ⅲ)更易被抗坏血酸还原成铁(Ⅱ)。结论黑木耳胶质比黑木耳多糖更易与铁(Ⅲ)形成复合物,可开发为高生物利用度的口服补铁剂。
Objective To compare the chemical composition of Auricularia auricula polysaccharide and the colloid, and the property of the different component-Fe complex. Method Auricularia auricula polysaccharide and the colloid were prepared first, then Auricularia auricula polysaccharide iron complex （APIC）and Aurcularia auricula glia iron complex （AGIC） were synthesized respectively with FeCl3 under alkaline condition, and their physicochemical property was determined. Results The stablility of AGIC was better than APIC and AGIC could be reduced to Fe（Ⅱ）by ascorbic acid more easily. Conclusion The Auricularia auricula colloid could combine with Fe（Ⅲ）easier than the polysaccharide, and would be expected to become a higher bioavailable iron-supplement.
