Abstract:
OBJECTIVE:To establish a method for the simultaneous determination of uracil,hypoxanthine,xanthine,uridine and adenosine in Eisenia foetida. METHODS:HPLC was performed on the column of Venusil XBP C18 with mobile phase of 50%methanol-0.01 mol/L potassium dihydrogen phosphate solution(gradient elution)at a flow rate of 1.0 ml/min. The detection wave-length was 254 nm with a column temperature at 30 ℃,and the injection volume was 10 μl. RESULTS:The linear range was 0.05-1.60 μg for uracil(r=0.9991),0.05-1.60 μg for hypoxanthine(r=0.9993),0.002-0.010 μg for xanthine(r=0.9991), 0.0075-0.24 μg for uridine(r=0.9999)and 0.0250-0.80 μg for adenosine(r=0.9990);RSDs of precision,stability and accuracy tests were lower than 3%;recoveries were 98.30%-100.76%(RSD=0.8%,n=9),98.68%-100.96%(RSD=0.8%,n=9), 95.16%-97.67%(RSD=0.9%,n=9),96.15%-99.57%(RSD=1.5%,n=9)and 96.39%-101.93%(RSD=1.8%,n=9),respective-ly. CONCLUSIONS:The method is simple and stable with good reproducibility,and can be used for the simultaneous determina-tion of uracil,hypoxanthine,xanthine,uridine and adenosine in E. foetida.
