摘    要:目的:建立高效液相色谱法同时测定复方水杨酸搽剂中3组分含量的方法。方法:采用Hypersil BDS C18(4.6mm×200mm,5μm)色谱柱,0.1mol·L^-1磷酸氢二钠溶液-甲醇(60:40,用20%磷酸调节pH5.0)为流动相,流速为1.0mL·min^-1,检测波长为212nm。结果:间苯二酚、水杨酸、苯酚分别在0.0388—0.776μg(r=0.9999),0.1176~2.352μg(r=0.9999)、0.0218~0.436μg(r=0.9999)范围内线性关系良好,3个浓度组间苯二酚的平均回收率分别为99.0%(RSD=0.3%),97.2%(RSD=0.5%),98.5%(RSD=0.8%),水杨酸的平均回收率分别为100.3%(RSD=0.4%),99.5%(RSD=0.7%),97.5%(RSD=0.6%),苯酚的平均回收率分别为97.1%(RSD=1.1%),97.8%(RSD=0.7%),99.6%(RSD=0.9%)。结论:本测定方法简便、快速、准确,为复方水杨酸搽剂质量评价提供了可靠方法。

Abstract:Objective: To establish an HPLC method for the determination of Three components in Compound Salicylic Acid Liniment at the same time. Method:The Hypersil BDS C18 (200 mm×4.6 mm,5 μm) column was used,the mobile phase consisted of 0. 1 mol· L^-1Na2HPO4- methanol (60: 40, adjust pH to 5.0 with 20% phosphoric acid), the flow rate was 1.0 mL ·min^- 1, the detection wavelength was 212 nm. Results:The linearity in the range for resorcinol, salicylic acid and Phenol were respectively 0. 038 8 -0. 776 μg ( r = 0. 999 9), 0. 117 6 - 2. 352 μg ( r = 0. 999 9), 0. 021 8 - 0. 436 μg ( r = 0. 999 9), and the average recoveries ( n = 3 ) were respectively 99.0% (RSD = 0. 3% ), 97.2% ( RSD = 0. 5% ), 98.5% ( RSD = 0. 8% ) ; 100. 3% ( RSD = 0.4% ), 99. 5% ( RSD = 0. 7% ), 97. 5% (RSD = 0. 6% ) and 97. 1% ( RSD = 1.1% ), 97. 8% ( RSD = 0. 7% ), 99.6% ( RSD = 0. 9% ). Conclusion: The method was found to be simple and accurate for simultaneous analysis of the content of 3 components in Compound Salicylic Acid Liniment, and provided a reliable way for evaluating the quality of it.
