Objective:To establish a method for determination of content of gentiopicroside in er tongⅡ.Methods:HPLC was adopted,DiamonsilTM-C18(200mm×4.6mm) was used,the mobile phase was acetonitrile-water(12:88),The wavelength was at 270nm. The quantitative determination of gentiopicroside was performed with external standard method. Results:the method has a good linear ; The average recovery rate for gentiopicroside was 98.94% and RSD was 2.95%. The RSD of the reproducibility was1.49%.Conclusions: The precision was high; The separation method is accurate, reproducible and highly selective. The method used for the determination of gentiopicroside in er tongⅡ is quite better. |
