【Abstract】 A new iron(Ⅲ) exocarpium Citri grandis polysaccharide complex (IEC) was synthesized using FeCl 3 and exocarpium Citri grandis polysaccharide at pH7~8. The results of infrared spectra and scanning electron microscopy showed that the structure of IEC was an interfacial complex. The particles consisted of an electron dense β FeOOH nucleus surrounded by an electron lucent layer of polysaccharide. As the complex is stable, without precipitation and dissociation at the physiological pH, IEC would be expected to be an iron supplementary agent for its higher bioavailability.\;更多还原
