摘要
目的 :建立天天风采颗粒剂中阿魏酸的含量测定方法。方法 :利用高效液相色谱法 ,对样品中阿魏酸的提取方法、测定条件进行选择。以含 1%冰醋酸的 6 0 %甲醇超声提取 ,检测波长 314nm。结果 :回收率 97.17% ( RSD =2 .6 1% )。结论 :该法简便易行 ,结果准确可靠 ,可作为天天风采颗粒剂质控方法。
Objective:To determine the content of ferulic acid in Tiantianfengcai granules. Methods:HPLC was used; the analytical column being Hypersil ODSZ (5 μm, 4.6 mm×250 mm). mobile phase, methanol water glacial acetic acid (27∶73∶1); detection wavelength, 314 nm. Results:The linear range of ferulic acid lay between 2～10 μg·ml 1 , r =0.999 8. The average recovery rate was 97.17% with an RSD of 2.61%. Conclusion:The method is easy to operate, with accurate and reliable results. It is therefore suitable for the quality control analysis of Tiantianfengcai granules.
