ABSTRACT
<p><b>OBJECTIVE</b>To analysis the nutrient and effective ingredients of in Cordyceps militaris and make the best use of its medical value.</p><p><b>METHOD</b>Adenosine, cordycepin, polysaccharides, cordyceps acid, protein and fat in different parts of C. militaris were extracted, they are quantified by HPLC and other colorimetric analysis.</p><p><b>RESULT</b>The contents of polysaccharide was found to be 86.49 mg x g(-1) in C. militaris, 6.82 mg x g(-1) of adenosine in stroma, 13.28 mg x g(-1) of cordycepin and 44.07 mg x g(-1) of cordyceps acid in sclerolium.</p><p><b>CONCLUSION</b>In different parts of C. militaris, the biosynthesis of effective ingredients is different. The total amount of effective ingredients is highest in C. militaris, the production of cordycepin and cordyceps acid is highest in sclerotium in comparison with other parts. Growth of C. militaris largely relies on its capability to utilize fat and protein from silkworm.</p>
