Four polysaccharides from the water extract of cultured Cordyceps militaris were isolated through ethanol precipitation, deproteination and gel-filtration chromatography. Their molecular weights were determined using gel-filtration chromatography. Among the four isolated polysaccharides, the structures of two of them (CPS-2 and CPS-3) were elucidated by sugar analysis, Smith degradation, IR and (13)C-NMR spectroscopy.
通过乙醇沉淀、脱蛋白和凝胶过滤色谱法，从人工培养的北虫草水提取物中分离出四种多糖。使用凝胶过滤色谱法测定它们的分子量。在分离出的四种多糖中，其中两种（CPS - 2和CPS - 3）的结构通过糖分析、史密斯降解、红外光谱和碳-13核磁共振光谱进行了阐明。
