川西小黄菊HPLC指纹图谱建立及7种成分含量测定

Establishment of HPLC fingerprints and content determination of seven constituents for Tanacetum tatsienense

目的建立川西小黄菊HPLC指纹图谱,并测定绿原酸、槲皮素-3-O-葡萄糖苷、木犀草素-7-O-葡萄糖苷、木犀草素-7-O-葡萄糖醛酸苷、芹菜素-7-O-葡萄糖醛酸苷、木犀草素、芹菜素的含量。方法分析采用Agilent ZORBAX Extend C_(18)色谱柱(4.6 mm×250 mm,0.5μm);流动相0.5%磷酸-乙腈,梯度洗脱;体积流量1.0 mL/min;柱温35℃;检测波长350 nm。再进行主成分分析、偏最小二乘法判别分析和聚类分析。结果14批样品指纹图谱中有12个共有峰,相似度0.761~0.975。7种成分在各自范围内线性关系良好(R^(2)≥0.9991),平均加样回收率84.00%~105.11%,RSD 1.28%~2.86%。各批样品聚为3类,发现7种差异成分,包括峰4(木犀草素-7-O-葡萄糖苷)、12(芹菜素)、9(芹菜素-7-O-葡萄糖醛酸苷)、8、11(木犀草素)、5(木犀草素-7-O-葡萄糖醛酸苷)、2。结论该方法精密稳定,专属性强,重复性好,可用于川西小黄菊的质量控制。

AIM To establish the HPLC fingerprints for Tanacetum tatsienens e(Bureau&Franchet)K.Bremer&Humphries and to determine the contents of chlorogenic acid,quercetin-3-O-glucoside,luteolin-7-O-glucoside,luteolin-7-O-glucuronide,apigenin-7-O-glucuronide,luteolin and apigenin.METHODS The analysis was performed on a 35℃ thermostatic Agilent ZORBAX Extend C_(18) column(4.6 mm×250 mm,0.5μm),with the mobile phase comprising of 0.5% phosphoric acid-acetonitrile flowing at 1.0 mL/min,and the detection wavelength was set at 350 nm.Subsequently,principal component analysis,partial least squares discriminant analysis and cluster analysis were carried out.RESULTS There were twelve common peaks in the fingerprints for fourteen batches of samples with the similarities of 0.761-0.975.Seven constituents showed good linear relationships within their own ranges(R^(2)≥0.9991),whose average recoveries were 84.00%-105.11% with the RSDs of 1.28%-2.86%.Various batches of samples were clustered into three types,and seven differential constituents were observable,containing peaks 4(luteolin-7-O-glucoside),12(apigenin),9(apigenin-7-O-glucuronide),8,11(luteolin),5(luteolin-7-O-glucuronide)and 2.CONCLUSION This precise,stable,specific and reproducible method can be used for the quality control of T.tatsienens e.
