摘    要:目的:建立测定蝎龙接骨散活性成分血竭素含量的高效液相色谱法。方法:采用VP—ODS(250mm×4.6mm,5μm)色谱柱,以乙腈-0.05mol·L^-1磷酸二氢钠溶液(45:55)(用磷酸调pH为3.5)为流动相,流速为1.0l·min^-1,检测波长:440nm。结果:血竭素在9.59~47.941μg·ml^-1浓度范围内,峰面积与浓度线性关系良好,r=0.9996,平均加样回收率为99.75%(RSD=0.99%)。结论:本法简便,准确,可用于蝎龙接骨散中血竭素的含量测定。

关 键 词:蝎龙接骨散  血竭素  高效液相色谱法

Abstract:Objective: To establish an HPLC method for determination the content of dracorhodin in Xielongjiegu powder. Method: Samples were determined by HPLC on a VP-ODS column(250mm × 4.6mm,5 μm) with a mixture of acetonitrile -0.05mol· L^-1 Natrium bihydrogen phosphanate ( adjusted pH to 3.5 with phosphoric acid) (45:55 ) as mobile phase, the flow rate was 1.0 ml· min ^- 1 and UV detection wavelength was at 440nm. Result: The calibration curves of dracorhodin was linear from 9.59 to 47.94μg·ml^-1 ( r = 0.999 6), the average recovery and RSD was 99.75% and 0.99%, respectively. Conclusion: The method is simple and accurate. It can be used for assay the content of dracorhodin in Xielongjiegu powder.
Keywords:Xielongjiegu powder  Dracorhodin  HPLC
