摘要 目的改进炎立消片中原儿茶酸含量测定方法。方法采用高效液相色谱法。色谱柱为UltimateTMXB-C18,流动相:甲醇-异丙醇-四氢呋喃-1.06%醋酸溶液(20∶8∶7∶950),流速:1.0mL.min^-1,检测波长:258nm,柱温:25℃。结果原儿茶酸在0.024-0.204μg范围内具有良好的线性关系(r=0.9998,n=6),平均回收率:98.19%(n=9),RSD=1.38%。结论该方法可用于炎立消片中原儿茶酸含量测定。 Objective To improve the method of determination of protocatechic acid in Yanlixiao tablets.Methods A HPLC method was established by using UltimateTM XB-C18 column as analytical colum.The mobile phase was methanol-isopropanol-THF-1.06% acetic acid solution(20∶8∶7∶950).The flow rate was 1.0 mL·min^-1,and detection wavelength was at 258nm.The column temperature was 25℃.Results The linear range of protocatechic acid was 0.024~0.204μg(r=0.9998,n=6) and the recovery of the method was 98.19%(n=9) with RSD=1.38%.Conclusion The method is suitable for the determination of protocatechic acid in Yanlixiao tablets.
