    摘 要 目的:建立同时测定野菊花中新绿原酸、绿原酸、隐绿原酸、咖啡酸、异绿原酸C、木犀草苷、蒙花苷、芹菜素8种活性成分含量的方法。方法:采用超高效液相色谱法。色谱柱为Waters ACQUITY UPLC BEH C18,流动相为0.1%磷酸溶液-乙腈(梯度洗脱),流速为0.3 mL/min,检测波长为335 nm,柱温为35 ℃,进样量为1 μL,样品室温为8 ℃。结果:新绿原酸、绿原酸、隐绿原酸、咖啡酸、异绿原酸C、木犀草苷、蒙花苷和芹菜素进样量检测线性范围分别为0.140~1.680、2.211~26.532、0.178~2.136、0.056~0.672、0.460~5.520、1.260~15.120、2.725~32.700、0.120~0.144 ng(r>0.999 6);检测限分别为0.02、0.02、0.02、0.01、0.01、0.01、0.04、0.01 ng,定量限分别为0.06、0.07、0.07、0.03、0.04、0.04、0.13、0.02 ng;精密度、稳定性(10 h)、重复性试验的RSD均0.999 6), respectively. The limits of detection were 0.02, 0.02, 0.02, 0.01, 0.01, 0.01, 0.04, 0.01 ng, and the limits of quantitation were 0.06, 0.07, 0.07, 0.03, 0.04, 0.04, 0.13, 0.02 ng, respectively. RSDs of precision, stability (10 h) and reproducibility tests were all lower than 2% (n=6). Average recoveries were 97.05%-102.04%(RSD=1.03%-1.65%, n=9). CONCLUSIONS: The established method has high analysis speed, high sensitivity, high resolution, good repeatability and accurate results. It can be used for simultaneous determination of 8 active components in D. indicum.
