中文摘要:目的:建立高效液相同时测定鹅不食草中5种倍半萜内酯成分:山金车内酯D、山金车内酯C、minimolide F、小堆心菊素C和短叶老鹳草素的含量测定方法。方法:采用AlltimaTM C18色谱柱(4.6 mm×250 mm,5 μm),水-乙腈为流动相,梯度洗脱,流速1.0 mL·min-1,检测波长223 nm,柱温35 ℃。结果:在线性范围内5个成分线性良好(r≥0.999 9),精密度RSD均小于2%;重现性RSD均小于3%;平均回收率94.09%~106.32%,RSD均小于2%。10批样品中5种成分含量范围为:423.3~1 437.2、144.1~498.0、29.8~159.2、66.8~188.8、1 290.1~3 476.4 μg·g-1。5种成分在不同批次的药材中的含量差异显著,短叶老鹳草素和山金车内酯D的含量较高,可作为鹅不食草质量控制指标性成分。结论:该方法操作简单、准确、灵敏度高、重复性好,对鹅不食草的质量评价与控制具有一定的参考意义。

Simultaneous Determination of Five Sesquiterpene Lactones in Centipeda minima by HPLC/UV Assay
Abstract:Objective:To develop an HPLC/UV method for simultaneous determination of 5 sesquiterpene lactones:arnicolide D,arnicolide C,minimolide F,microhelenin C and brevilin A,in Centipeda minima.Methods:The HPLC assay was carried out on an AlltimaTM C18 chromatographic column(4.6 mm × 250 mm,5 μm)by a gradient elution using water-acetonitrile.The detection wavelength was set at 223 nm,flow rate at 1.0 mL·min-1 and column temperature at 35 ℃.Results:The developed method had good linearities(r≥ 0.999 9),precision(RSDs ≤ 2%),repeatability(RSDs ≤ 3%)and accuracy due to all average recoveries ranged from 94.09% to 106.32%(RSDs ≤ 2%).The contents of 5 components in 10 samples ranged in 423.3~1 437.2,144.1~498.0,29.8~159.2,66.8~188.8,1 290.1~3 476.4 μg·g-1,respectively.The contents of 5 components in different batches of sample were significantly different,and the contents of brevilin A and arnicolide D were relatively higher,which could be used as the quality control index components for this herb.Conclusion:This method is simple,accurate,sensitive and reproducible,and has certain reference significance for the quality evaluation and control of C.minima.
