摘 要:目的:建立一种超高效液相色谱法(UPLC)检测不同产地、不同部位小叶黑柴胡中黄酮含量的方法。方法:Acquity UPLC BEHTMC18色谱柱(2.1 mm×50 mm,1.7μm),流动相为甲醇-0.1%H3PO4水梯度洗脱,流速0.4 mL.min-1,柱温30℃,检测波长为256 nm。结果:3个黄酮成分芦丁、槲皮素、异鼠李素分离良好,线性范围分别是0.1061.06μg,r=0.9998(n=6);0.004 870.048 7μg,r=0.999 7(n=6);0.022 00.220μg,r=0.999 8(n=6)。结论:该方法测定小叶黑柴胡中黄酮类成分的含量,具有简便准确。An ultra performance liquid chromatography method has been developed for determination of flavones in different origin and different parts from Bupleurum smithii var.parvifoliaum.The separation was performed at 30 ℃ on an Acquity UPLC BEHTM C18 column eluted with methanol and 0.1% phosphoric acid solution as mobile phases in gradient elution.The detection wavelength was set at 256 nm and the flow rate was 0.4 mL·min-1.There flavones of rutin,quercetin and isorhamnetin were separated well,the linear calibration curves were obtained over the ranges of 0.106-1.06 μg for rutin(r=0.999 8,n=6),0.004 87-0.048 7 μg for quercetin(r=0.999 7,n=6),0.022 0-0.220 μg for isorhamnetin(r=0.999 8,n=6).The mean recoveries of the three compounds were 99.3%,97.8%,98.9% with RSD of 2.4%,3.0%,3.2%.The result showed that the method is convenient and feasible for determination of the flavone content in B.smithii var.parvifoliaum.
