摘要
本研究为了对茶树菇保健食品的研究开发提供理论依据,研究了茶树菇中的功能因子——真菌水溶性多糖。研究中首次分离纯化得到五种茶树菇水溶性多糖,并进一步分析研究其中含量最大的多糖AP2的物理化学组成。结果表明,AP2分子量为122460,是由D-葡萄糖、D-甘露糖、D-木糖和半乳糖醛酸组成的酸性多糖,其中半乳糖醛酸含量为6.8%。
This study is in the interest of providing the theoretical basis for the healthy food exploitation ofAgrocybe 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%.
