Objective: The research aimed to compare two different determination methods of doxycycline hydrochloride content. Method: The ultraviolet spectrophotometry method and HPLC method were used to determine doxycycline hydrochloride content. Result: The standard curve of ultraviolet spectrophotometry method showed a good linear relationship from 0.002 mg/mL to 2.8 mg/mL and the average recovery was 99.12 % (n=5, RSD=1.79 %).The standard curve of HPLC method showed a good linear relationship from 0.005 mg/mL to 0.180 mg/mL and the average recovery was 99.90 % (n=5, RSD= 1.76 %). Conclusion: The ultraviolet spectrophotometry method was more convenienct, the HPLC method was more reliable.
