【摘要】 研究蒲公英多糖铁的制备工艺及其理化性质。将蒲公英多糖与氯化铁反应制得蒲公英多糖铁（Ⅲ）,测定一般理化性质和铁含量,用红外光谱对其结构进行分析,并以蒲公英多糖铁的产率和铁含量为评价指标,通过正交试验确定其最佳制备工艺条件。结果表明,蒲公英多糖铁为无定型红棕色粉末,易溶于水,与Fe³⁺形成稳定的配合物,不存在游离Fe³⁺,在空气中可以稳定存在,蒲公英多糖铁中铁（Ⅲ）含量为22.7%。蒲公英多糖铁的最佳制备工艺条件为:蒲公英多糖与柠檬酸三钠质量比2︰1、反应温度60℃、反应液pH 8。更多还原

【Abstract】 The optimization of Taraxacum polysaccharides iron complex and its physical and chemical properties were studied Taraxacum polysaccharides was reacted with ferric chloride to obtain araxacum polysaccharides iron complex,its common physical and chemical properties and the content of Fe were measured.The structure of Taraxacum polysaccharides iron complex was identified by infrared spectroscopy.Using the iron content in Taraxacum polysaccharides iron complex and the output as the reference index,explore the factors of the best synthesis technique of Taraxacum polysaccharides iron complex by orthogonal.The result showed that Taraxacum polysaccharides iron complex was amorphous reddish-brown powder and highly soluble in water.The complex combined with Fe³⁺was stable without any free Fe³⁺at the air.The iron content of Taraxacum polysaccharide iron complex was 22.7%.The best synthesis technique of Taraxacum polysaccharides iron complex was that the mass ratio of Taraxacum polysaccharides and catalystn 2︰1,the temperature 60℃,and the pH 8.更多还原
