| [目的] 建立不同产地元宝草中12个成分含量同步检测方法，并采用化学计量学和熵权逼近理想解排序(entropy weight-technique for order preference by similarity to an ideal solution，EW-TOPSIS)法对其质量进行评价。[方法] 采用Agilent 5 TC-C18色谱柱，以0.5%磷酸-乙腈为流动相，流速1.0 mL·min-1，检测波长254 nm和210 nm，以芒果苷为内参物，建立其与芦丁、金丝桃苷、槲皮素、山柰酚、Ⅰ3，Ⅱ8-双芹菜苷元、1，7-二羟基呫吨酮、1，3-二羟基-5-甲氧基呫吨酮、1，3，6，7-四羟基呫吨酮、大黄素、大黄素甲醚、贯叶金丝桃素的相对校正因子，并计算含量，同时以外标法测定18批元宝草中12个成分的含量；采用化学识别模式和EW-TOPSIS法建立元宝草质量优劣评价模型，对其整体质量进行综合评价。[结果] 外标法方法学考察结果均符合《中国药典》要求；一测多评(quantitative analysis of multi-components by single marker，QAMS)法与外标法所得含量结果无明显差异。主成分分析(principal component analysis，PCA)结果显示18批样品聚为3类；正交偏最小二乘法-判别分析(orthogonal partial least squares-discriminant analysis，OPLS-DA)将18批样品显著分类，筛选出导致不同产地元宝草质量差异的5个差异标志物；EW-TOPSIS法分析结果显示四川、贵州和广西产地元宝草整体质量较好。[结论] 元宝草中12种成分含量测定的QAMS法，操作便捷，结果准确；化学模式识别及EW-TOPSIS法客观全面，可用于元宝草的整体质量评价。 |

| [Objective] To establish a method for simultaneous determination of 12 components of Hypericum sampsonii from different producing areas， and evaluate its quality by chemometrics and entropy weight-technique for order preference by similarity to an ideal solution(EW-TOPSIS). [Methods] The analysis was performed on a Agilent 5 TC-C18 column with mobile phase consisting of 0.5% phosphoric acid-acetonitrile solution(gradient elution)at a flow rate of 1.0 mL·min-1. The detection wavelength was set at 254 nm and 210 nm. Relative correction factor(RCF) for rutoside， hyperoside， quercetin， kaempferol，3，8’-biapigenin， euxanthone，1，3-dihydroxy-5-methoxy-xanthone， norathyriol， emodin， physcion， hyperforin and mangiferin was established with mangiferin as internal reference， and the contents were calculated， and 12 components were determined by external standard method(ESM) method. Chemical mode identification and EW-TOPSIS method were used to establish the quality evaluation model of Hypericum sampsonii， and the overall quality was evaluated comprehensively. [Results] The methodological examination results of the external standard method all met the requirements of Chinese Pharmacopoeia. There was no significant difference in the content results between the QAMS method and the ESM. The principal component analysis(PCA) results showed that 18 batches of samples were clustered into 3 categories; the orthogonal partial least squares-discriminant analysis(OPLS-DA) analysis results showed that 18 batches of samples were significantly classified， and 5 differential biomarkers that caused differences in the quality of Hypericum sampsonii from different regions were screened out; EW-TOPSIS analysis results showed that the overall quality of Hypericum sampsonii from Sichuan， Guizhou and Guangxi provinces were better. [Conclusion] The established HPLC-QAMS method for simultaneous determination of 12 components in Hypericum sampsonii are convenient and accurate. Chemical mode identification and EW-TOPSIS method are objective and comprehensive， which can be used for the overall quality evaluation of Hypericum sampsonii. |
