摘要
目的建立当归片中阿魏酸的含量测定方法。方法采用HPLC法,C18ODS色谱柱,甲醇-水-磷酸(30:70:0.3)为流动相;流速为1.0ml/min;检测波长为320nm。结果阿魏酸进样浓度在3.75～75.01μg/ml线性良好,平均回收率为99.5%,RSD为1.23%。结论本文建立的HPLC法可作为当归片质量控制方法。
Objective: To establish a method for determining ferulic acid in Danggui tablet. Methods: The ODS C18 column was used. The mobile phase was methanol-water-phosphoric acid solution (30:70:0.3). The flow rate was 1.0ml/min. The detective wavelength was 320nm. Results: The linear range of ferulic acid concentration was 3.75～75.01μg/ml, The average recovery was 99.5%, RSD was 1.23%(n=6). Conclusions: The method is simple, fast and accurate. It can be used for the quality control of Danggui tablet.
