ABSTRACT
OBJECTIVE:
To establish a method for simultaneous determination of 5 nucleoside from different parts of cultured Cordyceps militaris.METHODS:
HPLC method was adopted. The determination was performed on InertSustain C18 column with mobile phase consisting of methanol-0.02 mol/L monobasic potassium phosphate solution (gradient elution) at the flow rate of 0.6 mL/min. The detection wavelength was set at 254 nm,the column temperature was 30 ℃.RESULTS:
The linear ranges of uridine, inosine,guanosine,adenosine and cordycepin were 0.568-3.408 μg(r=0.9999),0.284-1.704 μg(r=0.9999),0.264-1.584 μg(r=0.9999),0.232-1.392 μg(r=0.9999)and 1.672-10.032 μg(r=0.9998),respectively. RSDs of precision,stability and repeatabili-ty tests were all lower than 3.0%. The recoveries were 98.2%-103.9%(RSD=1.97%,n=9),96.2%-101.6%(RSD=1.76%,n=9),96.7%-102.0%(RSD=1.94%,n=9),95.1%-99.4%(RSD=1.43%,n=9) and 95.6%-101.3%(RSD=1.82%,n=9). CON-CLUSIONSThe method is simple,precise,stable and repeatable,and can be used for simultaneous determination of 5 nucleoside from cultured C. militaris,the content of nucleosides are different in different parts of C. militaris.
