In this study, three chemically sulfated polysaccharides (SPAPs) were derived from one water-soluble polysaccharide (PAP) of Polyporus albicans mycelia by chlorosulfonic acid-pyridine method. The effects of polysaccharides on the immune function were examined after the mice were intragastrical administrated with
