摘　　要：　目的：建立复方氢醌乳膏中氢醌的含量测定方法。方法：采用双波长紫外分光光度法测定氢醌的含量。结果：氢醌在4．06～24．36μg／mL范围内线性关系良好（r=0．9998，n=6），平均回收率95．87％，相对标准偏差为0．51％。结论：该含量测定方法简便快速，结果准确。Objective： To establish a method for determining the content of hydroquinone in compound hydroquinone cream. Methods： The dual wavelength UV-spectrophotometric method was used for hydroquinone analysis. Results： The linear range of hydroquinone was 4.06 μg/mL - 24.36 μg/mL （ r = 0. 999 8, n = 6） , the average recovery was 95.87 % , RSD was 0. 51%. Conclusion ： This method is simple ,rapid and accurate.
