摘　　要：从马齿苋中提取马齿苋多糖,在碱性条件下,马齿苋多糖水溶液与三氯化铁反应合成马齿苋多糖铁配合物,并用邻菲罗啉分光光度法测定马齿苋多糖铁中铁(Ⅲ)的含量。实验结果表明马齿苋多糖铁为红棕色无定型粉末,易溶于水,在100℃以下可以稳定存在,在pH3～12内不沉淀,不水解,马齿苋多糖铁中铁(Ⅲ)的含量为18.21%。马齿苋多糖铁具备开发为口服补铁剂的应用前景。Polysaccharide was extracted from Portulace oleracea L., then Portulace oleracea L. polysaccharide iron complex was synthesized with polysaccharide and FeCI3 under the alkaline condition. The determination of Fe（ll]） was conducted with the method of ferroin-Fe（]I）. The results showed that： Portulace oleracea L. polysaccharide iron is heavy brownish red and shapeless powder, It can dissolve in water, its chemical properties is very stable at the temperature below 100 ~ and the pH from 3 to 12. Content of Fe（lll）in Portulace oleracea L. polysaccharide iron is 18.21% by the method of ferroin- Fe（]]）. Portulace oleracea L. polysaccharide iron has developed the application prospects of oral iron supplement.
