目的:建立拨云锭中龙胆苦苷的含量测定方法。方法:采用高效液相色谱法测定拨云锭中龙胆苦苷的含量,以Agilent
TC-Cl8(4.6 mmx150 mm,5 μm)为分析柱,流动相为甲醇-水,检测波长为274 nm。结果:龙胆苦苷含量在0.219 2~2.192 0 μg时,线性关系良好(r=0.999 8),平均回收率为97.6%(n=9),RSD为2.37%。结论:此方法操作便、回收率高,重现性好,可用于本品中龙胆苦苷的含量测定。
Objective:To establish a method to determine the content of gentiopicroside in Boyunding.Methods:The content of gentiopierosidewasdeterminedbyhighperformanceliquid chromatography.Agilent TC-C1 8 (4.6 mm ×150 mm,5 μm ) was used as analytical column,the mobile phase was composed of methanol amt warer,the detection wavelength was 274 nm.Results:The calibration curve has shown a good linear pattern in gentiopicroside content within 0.219 2~2.192 g(r=0.999 8),the average recovery ratewas 97.6% (n=9)
and RSD was 2.37% .Conclusion:The simple,stable and reproducible properties of this method enable its application in content measuration of gentiopicroside in Boyunding.
