摘 要:目的建立高效液相色谱法同时测定脚癣净粉中苯甲酸、水杨酸、呋喃西林的含量。方法采用Agilent C18色谱柱(250mm×4.6mm,5gm),流动相为0.05mol·L^-1磷酸氢二钠溶液.甲醇(85:15),紫外检测波长为241nm,流速为1.0mL·min^-1,柱温为30℃,外标法计算含量。结果苯甲酸、水杨酸、呋喃西林分别在12.74~254.8gg·mL^-1(r=1.000),12.95~259.1μg·mL^-1(r=1.000)。2.16~43.36gg·mL^-1(r=0.9999)与峰面积线性关系良好,平均加样回收率分别为99.5%(RSD:0.5%),100.1%(RSD=0.4%)和99.6%(RSD=0.4%)(n=6)。结论该方法简便、准确、重复性好,可同时测定脚癣净粉中苯甲酸、水杨酸、呋喃西林的含量,为该制剂的质量控制提供可靠依据。Objective To establish an HPLC method for the simultaneous determination of the content of benzoic acid, salicylic acid and furacilin in Athlete's foot net powder. Methods Agilent C18 (250 mm×4.6 mm, 5 μm) column was used. The mobile phase was 0.05 mol . L^-1Na2HPO4 and methanol (85 : 15). The detection wavelength was 241 nm, the flow rate was 1.0 mL . min^-1, and the column temperature was 30 ℃ . Results The linearity for benzoic acid, salicylic acid and furacilin was 12.74 -- 254.8 μg . mL^- 1 (r = 1.000), 12.95 - 259.1μg . mL^-1 (r = 1.000) and 2.16 -- 43.36 μg . mL^-1 (r= 0.999 9). The average recoveries were 99.5% (RSD = 0.5%), 100.1% (RSD = 0.4%), and 99.6% (RSD = 0.4%) (n = 6). Conclusion The method is simple, accurate and reliable, which can be used for the content determination of benzoic acid, salicylic acid and furacilin in Athlete's foot net powder, and control the quality.
