摘要
目的建立土鳖虫药材中尿嘧啶和尿囊素的含量测定方法。方法采用高效液相色谱法,色谱柱为AlltimaNH2(150 mm×4.6 mm,5μm);流动相为乙腈-水(90:10);流速为1.0 ml/min,检测波长205 nm;柱温35℃。结果尿囊素和尿嘧啶的线性范围分别是:0.404~3.23μg(r=0.999 5,n=5),0.820~6.56μg(r=0.999 5,n=5)。平均回收率分别为98.8%、99.0%,RSD分别为0.96%、0.79%(n=6)。结论该方法简便、准确,可作为土鳖虫药材的质量控制方法。
Objective To establish a method for determination of uracil and auantion in Eupolyphaga seu Steleophaga by HPLC.Methods The HPLC separation was performed on Alltima NH2(150 mm×4.6 mm,5 μm)column with a mixture of acetonitrile-water(9010)as the mobile phase,at a flow rate of 1.0 ml/min.Detection wavelength was at 205 nm,and column temperature was at 35 ℃.Results The linear response of Auantion and Uracil range from 0.404~3.23 μg(r=0.999 5,n=5)and 0.820~6.56 μg(r=0.999 5,n=5);the average recovery was 98.8% with RSD 0.96% and 99.0% with RSD 0.79% respectively(n=6).Conclusion The method is simple,accurate and suitable for the determination of auantion and uracil in Eupolyphaga seu Steleophaga.
