中文摘要:
      目的:建立测定儿童Ⅱ号中的龙胆苦甙含量的方法。方法:采用高效液相色谱法,以DiamonsilTM–C18( 4.6×200mm,5μm)为色谱柱,以乙腈∶水(12∶88)流动相?熏流速:1.0mL/min,检测波长270nm,外标法定量。结果:此法线性关系良好,平均加样回收率为98.94%,RSD为2.95%;重复性RSD为1.49%。结论:本方法精密度高,分离度良好,可为测定儿童Ⅱ号中龙胆苦甙的含量提供可靠的分析方法。
英文摘要:
      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.
