Objective: To optimize the determination method for three components in metronidazole, clotrimazole and chlorhexidine acetate suppositories. Methods: An optimizative HPLC was used to deter-mine three components in metronidazole, clotrimazole and chlorhexidine acetate suppositories. The CAPCELL PAK C18 column (250 mm×4.6 mm, 5 μm) was used. The mobile phase consisted of methanol-water-triethy-lamine (70∶30∶0.3) (consisted sodium heptanesulphonate 10 mmol·L-1, adjusted by phosphoric acid to pH 6.0), The flow rate was 1.0 mL·min-1 and the column temperature was 30 ℃. The UV detection wavelength was set at 260 nm. Results: Optimizing studies showed that the three components had good resolutions. The linear ranges were 53.2~425.6 μg·mL-1 for metronidazole, 70.78~326.24 μg·mL-1 for clotrimazole and 1.87~14.92 μg·mL -1 for chlorhexidine acetate with the correlation coefficient 0.9999, 0.9999 and 0.9998, respectively. The average recoveries were 99.69% with 1.32.% , 99.64% with 1.27% and 99.92% with 1.45% (n=9). Conclusions: The optimized method can improve the precision and accuracy of the determi-nation method to achieve better quality control.
