摘要:目的采用高效液相色谱法测定感冒止咳颗粒中葛根素的含量。方法Agilent Eclipse XDB-C18柱 ( 4.6 mm×200 mm,5 μm);以甲醇-水溶液(28∶72) 为流动相;检测波长为250 nm,流速为1.0 mL·min-1,柱温:35 ℃。理论板数按葛根素峰计算应不低于4 000。 结果 葛根素与其相邻杂质峰能完全分离,葛根素进样量在0.088 22~0.441 1 μg 之间与峰面积呈良好的线性关系,相关系数R2=1.000 0,平均加样回收率为97.66%,RSD=0.8017%(n=6)。结论 本方法操作简便,精密度好,结果准确可靠,可用于感冒止咳颗粒的质量控制。

Abstract:ObjectiveTo establish a method for the determination of puerarin in Ganmao Zhike Granules by HPLC.MethodsThe C18 column (4.6 mm× 200 mm,5 μm) was adopted with the mobile phase of methanol-water(28∶72)at the flow rate o f 1.0 mL·min-1,and the detection wavelength was 250 nm.Theoretical plate number should not be less than 4 000 according to the puerarin peak.ResultsThe date showed that this method could clearly separate puerarin peak from its nearby impurity peaks,with a better linear range of 0.008 82~ 0.441 1 μg(R2=1.000 0),and the average recovery was 97.66% and the RSD was 0.801 7% (n=6).ConclusionThis method was simple,accurate and reliable,so it can be used for the quality control of Ganmao Zhike Granules.
