百合多糖铁(Ⅲ)配合物的制备及一般性质研究

The preparation and physico-chemical character of lily polysaccharide-Fe(Ⅲ) complex

目的 百合多糖铁配合物（LPC）的制备及其性质的研究。方法 热水浸泡法提取百合多糖；在碱性条件下，百合多糖水溶液与三氯化铁反应制备LPC。结果 LPC为深棕红色无定型粉末，含铁量为20．1％，易溶于水，在pH3-12较稳定。结论 LPC铁有望开发成为口服补铁剂。

OBJECTIVE To prepare lily polysacchafide- Fe （Ⅲ）complex （LPC） and study its character. METHODS Lily polysaccharide was extracted with hot water, and was used to prepare LPC with FeCl3 under the alkaline condition. RESULTS LPC was deep red brownish and shapeless powder, with 20. 1% content of Fe（Ⅲ）. LPC was able to dissolve in water,and was stable at pH3 to pil12. CONCLUSION LPC would be expected to be a better iron -supplementary agent.
