A study on Cordyceps militaris polysaccharide purification, composition and activity analysis

In this study, raw Cordyceps militaris polysaccharide (CPS) was extracted with ultrasonic- assisted extraction method. Proteins in the raw CPS were removed with the enzymatic and Sevag methods. After dialysis, an extraction rate of 0.82% was achieved. Two components, namely CPS-1 and CPS-2, were obtained from DEAE-52 ionic exchange chromatography eluted with NaCl solution at a gradient from 0 to 0.6 mol•L-1. The ultraviolet scanning demonstrated...
