Abstract: Objective: To explore the best synthetic process of Limonium bicolor polysaccharide-Fe (III) complex (LPC) and its physical and chemical properties. Methods: The synthetic process conditions were optimized by response surface methodology. The stability of LPC under physiological conditions was evaluated by its hydrolysis characteristics and reducibleness. Results: The optimal synthetic conditions were water bath temperature of 73℃, polysaccharides-to-C6H5Na3O7·2H2O ratio of 5:1 and reaction pH of 8. The prepared LPC was stable under physiological pH environment. Conclusion: LPC has excellent physicochemical properties and can be used as a new iron supplement.

Key words: Limonium bicolor, polysaccharide-Fe (Ⅲ), response surface methodology, physicochemical properties
