The polysaccharide,adenosine and mannitol components of Cordyceps taii collected from the wild were determined,and the effects of aqueous C.taii extracts on immune functions in mice were investigated using carbon clearance and delayed-type hypersensitivity testing(DTH),and by determining thymic and splenic indices.Polysaccharide,adenosine and mannitol levels in C.taii were 36.20 mg/g,0.27 mg/g and 80.20 mg/g,respectively.Aqueous C.taii extracts partially alleviated the suppressive effects on the thymic and splenic indices caused by cyclophosphamide,and increased nonspecific immunity and cellular immune functions.Toxicity tests revealed that the LD50 for aqueous C.taii extract on oral administration was >69.42 g/kg.
