摘 要:目的:建立归龙筋骨宁片中阿魏酸的含量测定方法。方法:采用Luna C18(2)柱(4.6mm×250mm,5um),流动相为甲醇-水-冰乙酸(69:30:1),检测波长:320nm。结果:阿魏酸含量在16.4—328.0ug/mL范围内有良好的线性关系(1=0.9997),加样回收率为99.50%,RSD为0.8%(n=6)。结论:本法简便、快速、准确,可作为归龙筋骨宁片中阿魏酸的含量测定方法。Objective: To establish a method to determine the contents of femlic acid in Guilengjinguning Tablets by HPLC. Methods:HPLC conditions :Luna C18(2)colunm(4. 6mm ID ×250mm,5um) was used. Three types of mixtures of methanol- water-acetic acid(69:30:1)as mobile phase and detection-wavelength was 320nm. Results:A good linearity was obtained in the range of 16. 4 - 328. 0ug/mL for ferulie acid. The linear equation was A = 68. 27C - 191.3 (γ = 0. 9997). Conclusion :The method is simple,rapid and accurate for determining the content of ferulic acid in Guilongjinguning Tablets.
