Study on synthesis and adsorption kinetics of Ganoderma lucidum Polysaccharide-Fe(Ⅲ) complex / 中国生化药物杂志

ABSTRACT

Objective To confirm the synthesis conditions of Ganoderma lucidum Polysaccharide-Fe (Ⅲ) Complex, and study on adsorption kinetics of it.Methods Adopt alcohol sedimenting technique and decoloring, dialysis, etc, extracting refined polysaccharide from Ganoderma lucidum.The solution of the Polysaccharide with FeCl3 react in alkaline conditions.To synthesize the polysaccharide iron complexes(GPC).The iron contents were determined by o-phenanthroline spectrophotography and and study on adsorption kinetics of Ganoderma lucidum Polysaccharide-Fe (Ⅲ) Complex.Results GPC is red brown and shapeless powder,it's liable to dissove in water,its solution is neutral,without precipitation,dissociation and Fe3 +at the pH from 3 to 12,and insoluble in organic solvents.So GPC is very stable.At the same time under different temperatures, the Fe3 + and polysaccharide on the adsorption quantity of increased gradually over time, the basic stability after 1.5 h.At the same time, with different temperatures the adsorption quantity of polysaccharide Fe3 + increases with the rise of temperature.Conclusion GPC may become a new ideal oral iron.Time and temperature are the key fabrication processes of GPC.
