  • The water-soluble crude polysaccharides obtained from the liquid culture broth of Cordyceps militaris by ethanol precipitation were fractionated by DEAE cellulose and Sepharose CL-6B column chromatography. This fractionation process resulted in three polysaccharide fractions that were termed CPSN Fr I, CPSN Fr II, and CPSN Fr III. Of the fractions, CPSN Fr II was able to upregulate the functional events mediated by activated macrophages, such as production of nitric oxide (NO) and expression of cytokines (IL-1 and TNF-).
