蒙药那仁满都拉及其配伍单药多糖铁的含铁量与性质分析
Analysis of Iron Content and Properties of Polysaccharide Irons in Mongolian Medicine Narenmandula and Its Compatible Single Drugs
摘要
Abstract
Using the Mongolian medicine Narenmandula and its 11 compatible single drugs as raw materials,poly-saccharides were extracted and 12 kinds of polysaccharide iron were prepared respectively,and qualitative and quanti-tative analyses were conducted on them.The formation of iron cores was characterized by infrared spectroscopy(IR),the iron content was determined by micro-indirect iodometric method,and the water solubility,stability,and reducibil-ity were examined by chemical analysis methods.The results showed that 12 polysaccharides formed Fe-OOH iron cores with Fe³+,exhibiting a polymeric β-Fe-OOH structure.All 12 polysaccharide iron complexes were amorphous powdery solids with good water solubility and stability.They could dissociate Fe³+ in acidic medium and could be re-duced by ascorbic acid(VC)in approximately 5 h.Their iron content ranged from 20.56%to 45.50%.These findings indicate that the 12 polysaccharides formed stable water-soluble complexes with Fe³+,which could be completely re-duced under the action of VC,and had good bioavailability.关键词
