A method was established for the quantitative determination of bioactive components,adenosine and cordycepin,in culture medium of Cordyceps militaris by reversed-phase high performance liquid chromatography. The separation was performed on Eclipse XDB-C18 column,The mobile phase was 0.02 mol/L phosphate buffer solution-methanol(volume ratio 85∶15). The flow rate was 1.0 mL/min,and the detection wavelength was 260 nm. The linear measurement range of adenosine was 0.5~100μg/mL(R=0.999 9);its average recovery was 105.3%;its standard RSD=0.76%(n=5);and its sample RSD=1.87%(n=5). The linear measurement range of cordycepin was 0.5~100 μg/mL(R=0.999 9);its average recovery was 104.0%;its standard RSD=0.95%(n=5);and its sample RSD=1.23%(n=5). The method has the characteristics with a wide linear range,a good degree of separation and a good precision. It can be used for quantitative analysis of adenosine and cordycepin in different culture medium for artificial Cordyceps militaris.
