摘要
目的:建立木通药材中木通苯乙醇苷B的HPLC分析方法。方法:采用Phenomenex Luna C18(4.6mm×250mm,5μm)柱,以甲醇.水.磷酸(35:65:0.05)为流动相,流速1.0mL·min^-1,检测波长330nm,柱温35℃。结果:木通苯乙醇苷B在0.04~0.86μg呈良好的线性关系,r=0.9998,平均回收率97.2%。对3个基源(三叶木通、五叶木通、白木通)的木通药材及其他部位(根、叶、果实)共39个样品进行了含量测定,各样品含量在0.021%~0.745%。结论:方法简单,重复性好,适合用于木通药材的质量控制。
Objective: To establish a quantitative method for calceolarioside B in Caulis Akebiae. Method: The samples were separated at 35℃ on a Phenomenex Luna C18 column eluted with methanol-water-phosphoric acid (35: 65: 0. 05) as mobile phase. Flow rate was at 1.0 mL · min ^-1 and the detection wavelength was at 330 nm. Result: The calibration curve was linear over the range from 0. 04 to 0. 860 g (r = 0. 999 8) and the average recovery was 97. 2%. 39 Crude drug materials collected from different areas were determined and the contents of calceolarioside B in Caulis Akebiae were fluctuated from 0. 021% to 0. 745%. Conclusion: The method is simple and repeatable and could be used for the quality control of Caulis Akebiae.
