【摘要】 采用食用菌为原料,采用微波辅助热水解提取法提取出复合多糖,并用凝胶树脂对提取液中复合多糖进行纯化.对复合多糖与锌离子配合反应及产物进行初步的探讨研究.确定最佳的反应条件为反应温度为60℃、反应时间为60 min、p H值为9.0,在此条件下,锌离子∶多糖配合比为1∶1(物质的量比).采用红外光谱对产物进行了表征.更多还原

【Abstract】 Compound polysaccharide was extracted using microwave- assisted thermal hydrolysis extraction method with edible fungus as raw materials and purified by Gel resin. The chelation between compound polysaccharide and zinc ion was preliminarily investigated. The optimal chelation condition was a reaction at 60 ℃,p H = 9. 0 for 60 min,and a molar ratio between zinc ion and polysaccharide of 1∶ 1. The product was characterized by infrared spectroscopy.更多还原
