摘要
目的 用反相高效液相色谱法测定复方当归片剂中阿魏酸的含量。方法 以Zorbax-C18为分析柱(5μm,4.6mm×250mm),流动相:5%乙酸溶液:甲醇(75:25),流速:1ml/min,检测波长:320nnm。结果 阿魏酸的浓度在0.0132~0.42mg/ml范围内与峰面积呈良好的线性关系(r=0.9997)。加样回收率为94.87%(RSD=0.5%)。结论 该方法简便、准确、可靠.可以作为复方当归片剂的质量控制指标之一。
Objective To determine ferulate acid in the compound angelica scinensis particle by RP-HPLC method. Methods The liquid chromatography was carried out using Zorbax C18 (5μm,4.6mm × 250mm), with detection wavelength at 320nm. The flow rate of mobile phase[5 % acetic acid -methanol(75:25 )] was ml/min. Resuits The calibration curve was linear in the range of 0.0141 ~ 0. 450mg/ml( r = 0. 9997, n = 5 ). The average recoveries was 94.87 % (RSD = 0.5 % ). Conclusion The method estahiishied in this paper can be adopr for the compound angelica seinensis particle. This method is simple, accurate, reliable and reproducible.
