| 中文摘要:建立了同时测定洋常春藤中绿原酸、隐绿原酸、芦丁、烟花苷、常春藤皂苷C、常春藤皂苷D、常春藤皂苷B和α 常春藤皂苷8种成分的超高效液相色谱法(UHPLC)。以80%甲醇为溶剂，将药材粉末于85 ℃、料液比1∶100条件下水浴回流1 h，制备供试品溶液；采用Agilent ZORBAX Eclipse Plus-C18(2.1 mm×100 mm，1.8 μm)色谱柱，以乙腈-0.05%磷酸溶液为流动相进行梯度洗脱。结果表明，上述8种成分均获得良好的分离度；仪器精密度、方法重复性的相对标准偏差(RSD)均小于3.0%；样品溶液在室温条件下24 h内稳定；8种成分在对应质量浓度范围内线性关系良好(r≥0.999 5)，检出限为0.40~10.58 μg·mL-1，定量下限为1.31~34.61 μg·mL-1，平均回收率为97.3%~108%，RSD(n=6)为0.51%~3.2%。该方法适用于洋常春藤中上述8种化学成分的定量分析。 |

| Abstract:A method of ultra high performance liquid chromatography(UHPLC) was developed for the simultaneous determination of eight components,ie.chlorogenic acid,cryptochlorogenic acid,rutin,nicotifiorin,hederacoside C,hederacoside D,hederasaponin B and α hederin in Hedera helix L..The dry leaves passed through 40 mesh sieve were put in 80% methanol with solid-liquid ratio of 1∶100.The solution then was refluxed by water bath for 1 h at 85 ℃ to prepare the test solution.The chromatographic separation was performed on an Agilent ZORBAX Eclipse Plus-C18(2.1 mm×100 mm,1.8 μm) column by gradient elution with acetonitrile and 0.05%phosphoric acid as mobile phases.Results indicated that the eight components in Hedera helix L.were well separated,and the relative standard deviations(RSD) of the method for precision and reproducibility were less than 3.0%.The eight components were found to be stable for 24 h in room temperature,and there existed good linear relationships for the analytes in corresponding mass concentration ranges with their correlation coefficients(r) not less than 0.999 5.The limits of detection and the limits of quantitation were in the ranges of 0.40-10.58 μg·mL-1 and 1.31-34.61 μg·mL-1,respectively.Average recoveries for the 8 components were between 97.3%and 108%with RSD(n=6) of 0.51%-3.2%.Therefore,this method could be applied in the quantitative analysis of the 8 components in Hedera helix L.. |
