目的:建立高效液相色谱结合一测多评法(HPLC-QAMS)同时测定葱莲花中4种化学成分(芦丁、异槲皮苷、烟花苷和紫云英苷)含量的方法。方法:采用HPLC-QAMS法,色谱柱为:Lubex Kromasil C18(250 mm×4.6 mm,5 µm),流动相:乙腈-0.1%磷酸水溶液梯度洗脱,测定波长:350 nm,流速:1.0 mL·min-1,柱温:30 ℃,进样量:10 µL。以芦丁为内参物,分别采用斜率校正、多点校正和单点校正法计算异槲皮苷、烟花苷、紫云英苷相对于芦丁的校正因子。采用相对保留时间定位色谱峰。以相对误差(RE)考察一测多评和外标法结果之间的差异,并评估一测多评的准确性和可行性。结果:芦丁、异槲皮苷、烟花苷、紫云英苷的线性范围分别为0.279~5.580 µg、0.013~0.260 µg、0.208~4.160 µg、0.019~0.372 µg(r≥0.999 9);精密度、稳定性、重复性试验RSD均小于2%(n=6);平均加样回收率范围为97.12%~98.47%(RSD<2%,n=9)。采用斜率校正和多点校正的QAMS法与外标法结果无显著差异,采用单点校正的QAMS法与外标法结果完全一致。结论:所建含量测定方法简便快捷、准确可靠,可用于同时测定葱莲花中4种活性成分的含量。

HPLC-QAMS法同时测定葱莲花中4种化学成分的含量
Objective: To establish a method for simultaneously determining the contents of four chemical components (rutin, isoquercitrin, nicotiflorin and astragalin) in Zephyranthes candida flowers by high performance liquid chromatography combined with the quantitative analysis of multi-components by single marker(HPLC-QAMS).Methods: The HPLC-QAMS method was adopted. The chromatographic column was Lubex Kromasil C18 (250 mm × 4.6 mm, 5 µm). The mobile phase was a gradient elution of acetonitrile-0.1% phosphoric acid aqueous solution. The detection wavelength was 350 nm. The flow rate was 1.0 mL·min-1. The column temperature was 30 ℃. The injection volume was 10 µL. Using rutin as the internal reference substance, the relative correction factors of isoquercitrin, nicotiflorin and astragalin relative to rutin were calculated by using the slope correction, multi-point correction and single-point correction methods respectively. The chromatographic peaks were located by the relative retention time. The difference between the results of the QAMS and the external standard method was investigated by the relative error (RE), and the accuracy and feasibility of the quantitative analysis of multi-components by single marker were evaluated.Results: The linear ranges were 0.279-5.580 µg for rutin, 0.013-0.260 µg for isoquercitrin, 0.208-4.160 µg for nicotiflorin, and 0.019-0.372 µg for astragalin(r ≥ 0.999 9). The RSDs of the precision, stability and repeatability tests were all less than 2%(n = 6). The range of the average sample addition recoveries was 97.12% - 98.47% (RSD < 2%, n = 9). There was no significant difference between the results of the QAMS method using slope correction and multi-point correction and those of the external standard method, and the results of the QAMS method using single-point correction were completely consistent with those of the external standard method.Conclusion: The established content determination method is simple, rapid, accurate and reliable, and can be used to simultaneously determine the contents of the 4 active components in Zephyranthes candida flowers.
