摘要: | 目的:建立测定溪黄草药材中迷迭香酸含量的方法。方法:采用高效液相色谱法。色谱柱为Inertsil ODS-SP C18,流动相为乙腈-0.4%磷酸(梯度洗脱),流速为1.0 ml/min,检测波长为327 nm,柱温为25 ℃,进样量为10 μl。结果:迷迭香酸的检测质量浓度线性范围为5.039~100.776 μg/ml(r=0.999 6);精密度、稳定性、重复性试验的RSD<3%;迷迭香酸的加样回收率为99.53%~104.86%(RSD=2.06%,n=9)。结论:该方法操作简单、重复性好、准确度高,可用于测定溪黄草药材中迷迭香酸的含量。 |
ABSTRACT: | OBJECTIVE: To establish a method for rosmarinic acid in Herba Rabdosiae Serrae. METHODS: HPLC method was performed on the column of Inertsil ODS-SP C18 with mobile phase of acetonitrile-0.4% phosphoric acid (gradient elution) at a flow rate of 1.0 ml/min, the detection wavelength was 327 nm, column temperature was 25 ℃, and injection volume 10 μl. RESULTS:The linear range of rosmarinic acid was 5.039-100.776 μg/ml(r=0.999 6),RSDs of precision, stability and reproducibility tests were lower than 3%; recovery was 99.53-104.38%(RSD=2.06%,n=9). CONCLUSIONS: The method is simple with good reproducibility and high accuracy, and can be used for the content determination of rosmarinic acid in Herba Rabdosiae Serrae. |
