摘要: | 目的:建立同时测定不同产地吴茱萸中绿原酸、吴茱萸碱、吴茱萸次碱含量的方法。方法 :采用超高效液相色谱法。色谱柱为ACQUITY UPLC BEH C18,流动相为乙腈-0.1%磷酸(梯度洗脱),流速为0.40 ml/min,检测波长为326、220 nm,柱温为30 ℃,进样量为2 μl。结果: 绿原酸、吴茱萸碱、吴茱萸次碱的检测质量浓度线性范围分别为7.67~76.67 μg/ml(r=0.999 2)、13.33~133.33 μg/ml(r=0.999 7)、13.33~133.33 μg/ml(r=0.999 8);定量限分别为0.11、0.05、0.05 ng,检测限分别为0.03、0.01、0.01 ng;精密度、稳定性、重复性试验的RSD<3%;加样回收率分别为96.19%~101.90%(RSD=2.19%,n=6)、95.35%~101.16%(RSD=2.27%,n=6)、95.92%~98.98%((RSD=1.33%,n=6)。结论: 该方法快速、准确,适用于同时测定不同产地吴茱萸中绿原酸、吴茱萸碱、吴茱萸次碱的含量。 |
ABSTRACT: | OBJECTIVE: To establish a method for the simultaneous determination of chlorogenic acid, evodiamine, rutecarpine in different places of Evodia rutaecarpa. METHODS: UPLC was performed on the column of ACQUITY UPLC BEH C18 with mobile phase of acetonitrile-0.1% Phosphoric acid aqueous solution (gradient elution) at a flow rate of 0.40 ml/min, the detection wavelength was 326 nm and 220 nm, column temperature was 30 ℃, and the volume injection was 2 μl. RESULTS: The linear range was 7.67-76.67 μg/ml for chlorogenic acid(r=0.999 2),13.33-133.33 μg/ml for evodiamine(r=0.999 7)and 13.33-133.33 μg/ml for rutecarpine(r=0.999 8); the limits of quantitation were 0.11 ng, 0.05 ng and 0.05 ng, the limits of detection were 0.03 ng, 0.01 ng and 0.01 ng,respectively; RSDs of precision, stability and reproducibility tests were lower than 3%; recoveries were 96.19%-101.90% (RSD=2.19%,n=6),95.35%-101.16%(RSD=2.27%,n=6) and 95.92%-98.98%(RSD=1.33%, n=6), respectively. CONCLUSIONS: The method is rapid and accurate, and suitable for the simultaneous determination of chlorogenic acid, evodiamine, rutecarpine in different places of E. rutaecarpa. |
