TITLE: | |
摘要: | 目的:建立同时测定软肝缩脾丸中芍药苷和丹酚酸B含量的方法。方法:采用高效液相色谱法。色谱柱为Wondasil C18,流动相为乙腈-0.1%磷酸溶液(梯度洗脱),流速为1.0 mL/min,检测波长为230 nm(芍药苷)、286 nm(丹酚酸B),柱温为30 ℃,进样量为10 μL。结果:芍药苷和丹酚酸B检测质量浓度线性范围分别为9.79~195.80 μg/mL(r=0.999 9)、11.45~229.00 μg/mL(r=0.999 9);定量限分别为0.018 1、0.014 4 μg,检测限分别为0.005 4、0.004 3 μg;精密度、稳定性、重复性试验的RSD<2.0%;加样回收率分别为98.67%~102.22%(RSD=1.26%,n=9)、99.72%~103.28%(RSD=1.05%,n=9)。结论:该方法快速、灵敏、准确,可用于软肝缩脾丸中芍药苷和丹酚酸B含量的同时测定。 |
ABSTRACT: | OBJECTIVE: To establish a method for simultaneous determination of paeoniflorin and salvianolic acid B in Ruangan suopi pill. METHODS: HPLC was performed on the column of Wondasil C18 with mobile phase of acetonitrile -0.1% phosphoric acid solution (gradient elution) at a flow rate of 1.0 mL/min, the detection wavelength was 230 nm for paeoniflorin and 286 nm for salvianolic acid B, the column temperature was 30 ℃, and the injection volume was 10 μL. RESULTS:The linear range was 9.79-195.80 μg/mL(r=0.999 9) for paeoniflorin, 11.45-229.00 μg/mL(r=0.999 9) for salvianolic acid B; the limits of quantification were 0.018 1,0.014 4 μg, limits of detection were 0.005 4, 0.004 3 μg; RSDs of precision, stability and reproducibility tests were lower than 2.0%; the recoveries were 98.67%-102.22%(RSD=1.26%,n=9) and 99.72%-103.28%(RSD=1.05%,n=9). CONCLUSIONS: The method is rapid, sensitive and accurate, and can be used for the simultaneous determination of paeoniflorin and salvianolic acid B in Ruangan suopi pill. |
