摘要
目的建立空心莲子草中穆坪马兜铃酰胺的含量测定方法。方法采用HPLC法定量分析空心莲子草中穆坪马兜铃酰胺的含量,色谱柱为Alltima C18(250mm×4.6mm,5μm),以乙腈-水(25:75)为流动相,检测波长220nm,流速1.0ml·min^-1,柱温30℃。结果穆坪马兜铃酰胺进样量在0.0541~1.0802μg范围内线性关系良好,线性回归方程为Y=6965.4X-2148.5,r=0.9997;平均回收率为101.9%,RSD=2.67%。结论该方法简便易行,准确可靠。
Objective To establish a determination method of the content of N - trans - feruloyl tyramine in Ahernanthera philoxerodes. Methods The content of N - trans - feruloyl tyramine in Ahernanthera philoxerodes was determined by HPLC and Alhima C18 column (250 mm ×4.6 mm,5μm) was used . The mobile phase was a mixture of acetonitrile - water (25:75 ) , column temperature was 30℃, the flow rate was 1 ml·min^-1 and the detection wavelength was 220 nm . Results The calibration curve of N - trans - feruloyl tyramine was linear over the range of 0. 054 1 - 1. 0802 μg , and the equation of linear regression was Y = 696 5.4X - 2 148.5 ( r = 0. 999 7). The average recovery rate was 101.9% ( RSD = 2.67% ). Conclusion The methed is simple and the result is accurate.
