摘 要:目的建立同时测定双黄连口服液中绿原酸、黄芩苷、连翘苷和汉黄芩素含量的高效液相色谱法。方法采用VP-ODSC18色谱柱(250mm×4.6mm,5μm);流动相:乙腈-0.2%磷酸溶液梯度洗脱;流速:1.0mL/min;检测波长:278nm。结果绿原酸在0.44~6.60μg范围内线性关系良好(r=0.9991),平均回收率为97.0%;黄芩苷在0.52~6.18μg范围内线性关系良好(r=0.9991),平均回收率为98.98%;连翘苷在0.20~2.04μg范围内线性关系良好(r=0.9993),平均回收率为103.55%;汉黄芩素在0.13~1.76μg范围内线性关系良好(r=0.9991),平均回收率为96.49%。结论本方法简便可行、准确、快速,可用于双黄连口服液中上述4种成分的含量测定。Objective To establish a HPLC method for the determination of chlorogenic acid, baicaliin, forsythin and wogonin in Shuanghuanglian oral liquid. Methods The column was VP-ODS C18 (250 mm× 4.6mm, 5μm). The mobile phase consisted of acetonitrile-0.2% phosphoric acid with gradient elution. The flow rate was 1.0 mL/min and the detection wavelength was at 278 nm. Results The calibration curves were linear within the range of 0.4446.60 μg (r =0.999 1) for chlorogenic acid, 0.5246.18 μg (r =0.999 1) for baicaliin, 0.2042.04 μg (r=0.999 3) for forsythin (r=0.999 3) and 0.1341.76 μg (r=0.999 1) for wogonin, respectively. The average recovery of them were 97.0% (RSD= 1.1%), 98.98% (RSD= 1.1%), 103.55% (RSD = 1.1%) and 96.49% (RSD = 1.1%), respectively. Conclusion The method is simple, practicable, accurate and rapid. It can be applied to content determination of chlorogenic acid, baicaliin, forsythin and wogonin in Shuanghuanglian oral liquid.
