摘要
目的:建立冠脉宁软胶囊中葛根素含量测定方法。方法:采用高效液相色谱法,以ODS—C18色谱柱(200mm×4.6mm,5μm),以甲醇-水(30:70)为流动相,检测波长为250nm。结果:葛根素在进样量为0.03616-0.32544μg范围内,有良好的线性关系(r=0.9998),方法的回收率为100.6%(n=6),RSD为1.10%。结论:本方法快速、准确。方法的稳定性、重复性良好,可作为冠脉宁软胶囊质量分析控制方法。
Objective: To establish a method of content determination of puerarin in Guan Maining soft capsule. Method: To adopt HPLC with ODS - C18, Chromatogrophic Column (200 × 4.6mm ,5μm ), Methanol : water ( 30: 70 ) as flouting appearance detection wavelength is 250nm. Result : The content of puerarin in Guan Maining soft capsule has a perfect linearity distribution between 0.03616 and 0. 32544μg( r = 0. 9998 ) , the average yield is 100.6%( n = 6) ,RSD is 1.10%. Conclusion: This method is fast ,accurate with a good epeatability and can be used for the quality control and analysis of Guan Maining soft capsule.
