Abstract: By assaying adenosine, cordycepin, polysaccharide, and cordyceps acid in Cordyceps militaris (Bombyx mori),Cordyceps militaris(pupa), and Cordyceps sinensis, the results showed that cordycepin production of 12.59mg/g in Cordycepsmilitaris (Bombyx mori) was 4.45-fold of that synthesized in Cordyceps militaris (pupa), while polysaccharide production wasalso 2.68-fold of that in Cordyceps militaris (pupa). Comparing with the Cordyceps sinensis, Cordyceps militaris (Bombyx mori)could produce 4-fold more of adenosine besides several hundred folds of cordycepin. Taking together, Cordyceps militaris (Bombyxmori) would be a new resource of medcine with good development potential.

Key words: Bombyx mori, Cordyceps militaris, cordycepin, adenosine, polysaccharide, cordyceps acid
