摘要
目的建立测定鼻炎滴剂中绿原酸和黄芩苷含量的方法。方法采用RP-HPLC法,色谱柱为Diamonsil^TMC18（250mm×4.6 mm,5μm）柱,以甲醇-水-磷酸（52∶48∶0.1）为流动相,检测波长320nm,流速为1.0 ml·min^-1。结果绿原酸在4.3034.40μg·ml^-1范围内线性关系良好,回归方程为：A=127.3C-4.396,r=0.999 9,平均回收率102.1%,RSD=0.94%;黄芩苷在15.52108.64 g·ml^-1范围内线性关系良好,回归方程为：A=38.15C＋55.1,r=0.999 7,平均回收率100.8%,RSD=1.4%。结论该法灵敏、简便、准确,可用于鼻炎滴剂的质量控制。
Objective To establish a method for determination of chlorogenic acid and baicalin in coryza dripping solution.Methods RP-HPLC method was used.The column was DiamonsilTM C18（250 mm×4.6 mm,5 μm）,the mobile phase was methanol-water-phosphoric acid（52∶48∶0.1）,the flow rate was 1.0 ml·min^-1,the detection wavelength was 320 nm.Results The linearity of chlorogenic acid was good in the range of 4.30～34.40μg·ml-1,regress equation was A=127.3C-4.396,r=0.9999,and average recovery rate was 102.1%,RSD=0.94%;the linearity of baicalin was good in the range of 15.52～108.64μg·ml-^1,regress equation was A=38.15C ＋55.1,r=0.999 7,average recovery rate was 100.8%,RSD=1.4%.Conclusion The method is sensitive,simple,accurate,and can be used for the quality control of coryza dripping solution.
