Objective: To establish a UV spectrophotometric method for the determination of naftifine hydrochloride solution. Methods: Multiple UV spectrophotometers were used to prepare the two concentrations of naftifine hydrochloride solution. The naftifine hydrochloride absorption coefficient (E1% 1cm) was determined and the content of the sample was determined. Results: The blank matrix did not interfere with the determination of the sample at the measurement wavelength. The linear range of naftifine hydrochloride was 1.6-16 μg · ml -1, r = 1.0 0 0 0, and the intraday deviation was 0.2% (n = 6 ), With an average recovery of 100.4% and RSD = 0.39% (n = 6). Conclusion: The method is sensitive and simple, and meets the requirements of determination of naftifine hydrochloride solution
