【摘要】 目的:建立以高效液相色谱法测定参芍肝康口服液中芍药苷含量的方法。方法:色谱柱为KromasilC18,流动相为甲醇-0.05mol/L磷酸二氢钾溶液-异丙醇(60∶173∶4,用醋酸调节pH值至4.0),检测波长为230nm,流速为1.0ml/min。结果:芍药苷检测浓度在0.027～0.230mg/ml范围内与峰面积积分值线性关系良好(r=0.9999);平均加样回收率为100.97%(RSD=1.28%,n=5)。结论:本方法简单、快速、精密度高、重现性好,可用于参芍肝康口服液的质量控制。更多还原

【Abstract】 OBJECTIVE:To establish HPLC method for the determination of the content of paeoniflorin in Shenshaoˉgankang oral liquid.METHODS:Paeoniflorin was separated on Kromasil C 18 ;methanol-0.05mol/L KH 2 PO 4 solution-avantin(60∶173∶4,which was adjusted to pH=4.0with acetic acid)was taken as the mobile phase with a flow rate at1.0ml/min and detection wavelength at230nm.RESULTS:Good linear relationship was achieved when the detection concentration range of peoniflorin was0.027～0.230mg/ml(r=0.9999);The average recovery of peoniflorin was100.97%(RSD=1.28%,n=5). CONCLUSION:The method was simple,rapid,precise and reproducible,which can be used as the quality control of Shenshaogankang oral liquid.更多还原
