摘 要:目的:建立同时测定白斑乳膏中氟尿嘧啶、氢化可的松、黄芩苷、维生素E含量的高效液相色谱法.方法:采用Aichrom Bond-AQ C18色谱柱(250 mm×4.6mm,5μm),流动相为甲醇-[0.5%醋酸(含6mmol·L-1庚烷磺酸钠)](70∶30),检测波长为267 nm,流速为1.0 ml·min-1,柱温为室温.结果:氟尿嘧啶、氢化可的松、黄芩苷、维生素E分别在1.61~14.49,8.032 ~40.16,21.92 ~284.48,48.13 ~433.17 mg·L-1浓度范围内线性关系良好(r≥0.9999),平均加样回收率分别为99.91%(RSD=0.96%)、99.79%(RSD=0.70%)、100.10%(RSD =0.44%)、99.50%(RSD =0.74%).结论:该方法准确可靠,重复性好,可用于白斑乳膏4组分的含量测定.Objective:To develop an HPLC method for the simultaneous determination of fluorouracil,hydrocortisone,baicalin and vitamin E in leukoplakia creams.Methods:The HPLC system consisted of an Aichrom Bond-AQ C18 (250 mm ×4.6 mam,5 μm) column,methanol-0.5% phosphoric acid solution (containing 6.0 mmol · L-1 sodium heptanesulfonate) (70:30) as the mobile phase,the UV detection wavelength at 267nm,the flow rate of 1.0 ml · min-1 and the column temperature of room degree.Results:The linear range of fluorouracil,hydrocortisone,baicalin and vitamin E was 1.61-14.49,8.032-40.16,21.92-84.48 and 48.13-433.17 mg · L-1(r≥0.999 9),respectively.The average recovery of the four compounds was 99.91% (RSD =0.96%),99.79% (RSD =0.70%),100.10% (RSD =0.44%) and 99.50% (RSD =0.74%),respectively.Conclusion:The method is accurate,reliable and reproducible,and can be used in the determination of the four components in leukoplakia creams.
