摘　　要：真菌多糖具有降血糖、抗肿瘤、抗氧化、抗病毒和免疫调节等多种生理功能,且对机体毒副作用小,具有广阔的开发前景。以营养价值和药用价值均较高的香菇(Lentinus edodes)、茶树菇(Agrocybe aegirit)为原料,用热水提取法在90℃、料液比1∶20(g∶m L)、提取1次、4 h的条件下,提取两种真菌多糖。结果表明,热水法提取香菇多糖的得率为9.70%,茶树菇多糖的得率为13.10%,说明茶树菇中的多糖含量高于香菇。该研究可为后续开发利用真菌多糖提供重要依据。Polysaccharides derived from fungi have vast development future because of their potent hypoglycemic effect,antitumor,anti-oxidation and anti-virus and immunomodulation properties. In the present studies,the fungal polysaccharides from Lentinus edodes and Agrocybe aegirit with hot water extraction were conducted. The influence factors was designed with water temperature 90 ℃,material-liquid ratio 1∶20,extraction time 4 h and extraction only once. The results showed that the extraction rate of L. edodes was 9.7%,while 13.1% in A. aegirit. That means the content of polysaccharides derived from A. aegirit is higher than L. edodes. This study provided scientific basis of fungal polysaccharides development.
