摘要
目的:建立一种同时测定抗感利咽糖浆中黄芩苷、虎杖苷含量的高效液相色谱法。方法:采用Waters SunFire C18色谱柱(250 mm×4.6 mm,5μm);乙腈为流动相A,0.2%磷酸溶液为流动相B,梯度洗脱,流速为1.0 ml·min-1,检测波长为284 nm,柱温为30℃。结果:黄芩苷、虎杖苷与其他成分分离度良好,无干扰;黄芩苷在32.0~480.0μg·ml-1的范围内有良好的线性关系,平均回收率为98.71%,RSD为0.67%;虎杖苷在16.0~240.0μg·ml-1范围内有良好线性关系,平均回收率为97.02%,RSD为1.03%。结论:所建立HPLC法可同时测定抗感利咽糖浆中黄芩苷和虎杖苷的含量,方法准确度高,稳定性好,可作为该制剂的含量测定方法。
Objective:To establish an HPLC method for the determination of baicalin and polydatin in Kanggan Liyan syrups. Methods:The samples were analyzed on an Waters SunFire C18 column with the mobile phase A of acetonitrile and the mobile phase B of 0. 2% phosphoric acid solution with gradient elution. The flow rate was 1. 0 ml·min-1 , the detection wavelength was 284nm,and the column box temperature was 30℃. Results:Baicalin and polydatin could be separated effectively without interference. The linear range of baicalin was 32. 0-480. 0 μg·ml-1 and the average recovery was 98. 71%(RSD=0. 67%,n=5). The linear range of poly-datin was 16. 0-240. 0 μg·ml-1 and the average recovery was 97. 02%(RSD=1. 03%,n=5). Conclusion:The method is accurate and stable, and can be used in the determination of Kanggan Liyan syrups.
