摘要
虫草发酵废液中含有多种有利用价值的营养成分。采用壳聚糖作为絮凝剂加以沉降处理,通过高效液相色谱的方法比较原发酵废液与絮凝后上清液的组成,证实絮凝所除去的主要是蛋白质、虫草多糖类大分子。将虫草发酵废液直接进行水解,高效液相色谱分析结果表明:虫草多糖的组成主要为甘露糖、葡萄糖、半乳糖,其含量比约为1:10 : 7。发展的液相色谱分离分析方法可以很好地将多糖、单糖等组分有效分离,也可用于对于其他有效活性组分的研究。
A lot of nutrient components are involved in the fermented waste water of the Cordyceps sinensis. Chitosan, as a kind of flocculating agent, is used to settlement the large molecules. The composition of the original waste water and the supernatant fluid after being flocculated was compared with HPLC. Also Cordycepic polysaccharides was hydrolyzed and analyzed. The results show that Cordycepic polysaccharides is involved with galacrose, glucose, mannitose 22 ： 205 ： 144.
