Structural characterization and antioxidant activity of purified polysaccharide from cultured Cordyceps militaris

The polysaccharide fraction, CM-hs-CPS2, was isolated from fruiting bodies of culturedCordyceps militaris grown on solid rice medium by hot water extraction and ethanol precipitation, and purified by ion exchange column (DEAE-cellulose-52) and gel filtration column (Sephadex G-100) chromatography. Its structural characterizations were analyzed by gas chromatograph (GC) and fourier transform infrared spectroscopy (FT-IR). Results indicated...
