目的建立测定舒肝止痛丸中芍药苷含量的高效液相色谱(HPLC)法并对其质量进行控制。方法色谱柱:Hibar~150-4,6 Purospher~STAR RP-18e(5μm)色谱柱,流动相:乙腈-0.1%磷酸水溶液(15∶85),流速:1.0 mL·min~(-1),柱温:25℃,检测波长:230 nm,进样量:5μL。结果芍药苷在0.0495~0.9907μg范围内线性关系良好(r=0.999 8),平均加样回收率为99.5%,RSD=1.6%(n=9)。结论该方法操作简便,结果准确,可用于测定舒肝止痛丸中芍药苷的含量。
Objective To establish a HPLC method for the determination of paeoniflorin in Shuganzhitong pill and to control its quality. Methods The mobile phase was acetonitrile-0.1% phosphoric acid solution (15:85), the mobile phase was Hibar ~ 150-4,6 Purospher ~ STAR RP-18e ), Column temperature: 25 ℃, detection wavelength: 230 nm, injection volume: 5μL. Results Paeoniflorin had good linearity (r = 0.999 8) in the range of 0.0495-0.9907 μg with an average recovery of 99.5% and a RSD of 1.6% (n = 9). Conclusion The method is simple, accurate and can be used to determine the content of paeoniflorin in Shuganzhitong pill.
