摘要: 用从银耳中提取的多糖和FeCl3为主要原料合成一种新的补铁剂——银耳多糖铁(Ⅲ)配合物(ITC),并测定了其理化性质。实验证明:在ITC水溶液中,不存在游离Fe3+,表明铁(Ⅲ)与银耳多糖形成了稳定的配合物.经红外光谱、超速离心及电镜观测可知:银耳多糖铁(Ⅲ)配合物是以β-(FeOOH)n。为微核,银耳多糖在其核表面络合而形成的表面配合物,其粒子直径约为30~80nm,属于高分子化合物。ITC在生理pH下不沉淀、不水解,可望有较好的生物利用度.

Abstract: A new kind of iron-supplementary drug——iron(Ⅲ)-tremella fuciformis polysaccha-ride complex(ITC)was synthesized with FeCl3 and tremella fuciformis.Because it was not free Fe3+in the ITCsolution,therefore this complex was very stabe.The investigation by infrared spectra,ultracentrifugation and electron microscopy showed that structure of ITCwas an interracial compex with β-(FeOOH)n.core and a high polymer.The diameters of complex particles ranged from 30~80 nm.Because it was not precipitated and dissociated at the physiological pH it higher bioavailability would be expected.
