摘  要:目的:采用高效液相色谱法检查阿昔洛韦分散片的有关物质。方法:色谱柱为C18,200×4.6mm,5μm,以甲醇:水(8:92)为流动相,检测波长为254nm。结果:阿昔洛韦浓度在0.5~7.5μg/mL范围内(r=0.9996,n=5),鸟嘌呤浓度在0.5~8.5μg/mL范围内(r=0.9996,n=5),线性均良好。有关物质测定重复性试验乌嘌呤RSD为1.0%(n=6);其他杂质RSD为1.3%(n=6)。结论方法简便、可靠,可用于生产的质量控制。Objective To establish HPLG method to determine the relative substances in Aeyelovir dispersed tables Method In the method C18(200 × 4.6mm,5μm) as the column and methanol-water(8:92) as the mobile phase and the detection wavelenth of 254nm was specified. Result The linear range of Acyclovir was 0.5 - 7.5μg/mL(r = 0.9996,n=5) and Guanine was 0.5- 8.5μg/mL(r = 0.9996,n = 5).Relative substances repeated experiments: RSD of Guanine was 1.0% (n = 6) , and RSD of other relative substances was 1.3 % ( n = 6). Conclusion The method is convenient, reliable. It can be used to quality control.
