摘　　要：目的采用反相高效液相色谱法测定甲硝唑阴道泡腾片中甲硝唑的含量。方法采用Alltima C18色谱柱(150mm×4.6mm,5μm),以甲醇-水(20∶80)为流动相,流速1.0mL·min-1,紫外检测器检测波长为320nm。结果RP-HPLC测定的线性范围为0.13～0.40mg·mL-1,r=1.000;样品溶液在24h内稳定;平均回收率为100.1%,RSD为1.0%(n=9);日内和日间RSD分别为0.7%和1.2%。结论采用RP-HPLC测定甲硝唑阴道泡腾片中甲硝唑的含量,专属性强,结果准确可靠。OBJECTIVE Establish a RP-HPLC method for the determination of the content of metronidazole in metronidazole vaginal effervescent tablet. METHODS Alltima C 18 （ 150 mm × 4.6 mm, 5 μ m） was used as the stationary phase. The mobile phase was methanol-water （20 ： 80）. The flow rate was 1.0 mL · min^-1, and the detection wavelength was 320 nm. RESULTS The method was proved to be linear in the range of 0.13-0.40 mg ·mL^-1（r = 1.000）. The average recovery of the method was 100.1% with RSD=1.0%（n=9）. The RSD of average contents of inter and intra-day was 0.7% and 1.2% respectively. CONCLUSIONS This method is simple, rapid, accurate and is suitable for determination of the content of metronidazole in metronidazole vaginal effervescent tablet.
