Determination of camphor in camphor cream by UV spectrophotometry
-
摘要: 目的 建立樟脑霜中樟脑的含量测定方法。方法 采用紫外分光光度法,以(289±1)nm波长处测定制剂中樟脑的含量。结果 樟脑含量在1.28～3.84mg/mL的浓度范围内,呈良好的线性关系(r=0.9999),平均回收率101.7±0.4%,RSD为0.4%。结论 本法简单、准确,能够排除制剂中基质的干扰,可用于樟脑霜质量控制。Abstract: Objective To develop a method for determination of content of camphor in camphor cream. Methods The content of camphor in camphor cream was determined by UV spectrophotometry.The detection wavelength was (289 ±1) nm. Results There was a good linear relation between camphor content and Abs in the range of 1.28～3.84mg/mL. The average recovery was 101.7% with RSD of 0.4%. Conclusion The method is simple and accurate.
