Studies on the Isolation, Purification and Composition of Water-solubility Polysaccharides from Agrocybe Chaxingu

Abstract

Abstract: This study is in the interest of providing the theoretical basis for the healthy food exploitation of Agrocybe Chaxingu, and to do research on the fungal water-solubility polysaccharides in it. Five kinds of water-solubility polysaccharides are first isolated from Agrocybe chaxingu. The study also analyzes the physical and chemical quality of AP2, the most part of the five. The results is showed that the molecular weight of AP2 is 122460, and AP2’ sugar composition comprises: D-Glu, D-Man, D- Xyl and Gal acid. It is an acid polysaccharide and the Gal acid content is 6.8%.

Key words: Agrocybe Chaxingu, water-solubility polysaccharides, isolation and purification, analysis of composition
