银耳(Tremella fuciformis Berk)为担子菌纲银耳科真菌。七十年代前后,国内外学者相继发现从银耳中可分离得到银耳多糖,具有复杂而又多方面的生物活性,引起研究者的关注。我们将银耳经提取、分离、纯化制得多糖,现就其药理活性和应用简介如下。 Tremella fuciformis Berk is a Basidiomycete fungus. Before and after the 1970s, scholars at home and abroad have found that Tremella polysaccharides can be isolated from Tremella fuciformis, which has complex and multi-faceted biological activities, which has attracted the attention of researchers. We have extracted, separated and purified the white fungus to obtain polysaccharides. Now we introduce the pharmacological activities and applications as follows.
