Abstract

Objective:To establish a determination method of camphor in camphor cream.Methods:With the wavelength of 289 nm and 294 nm as the determinable points,the signal multiplier method was used.Results:The detector response was linear in the range of 0.5-2.5 mg/ml(r=0.999 8) for camphor.The average recovery was 100.6%,RSD=1.05%(n=5).Conclusion:The method is accurate and simple,reliable convinient and stable.It can be used for quality control of camphor cream.
