Abstract Objective: to establish a quantitative analysis method for oflxacin capsules. Methods: 0.1mol/L hydrochloric acid was used as the solvent, and the wavelength of detection was (293±1)nm . Results: The linear range was between 2～9μg/ml, with regression equation of A=0.0919118ρ+0.00119608, r=0.999998, average recovery of 100.5% (n=9), and RSD=078%. Conclusions: The method is simple and accurate.
