目的 建立参贝止咳颗粒中重楼皂苷VII、VI、I及白花前胡甲素、白花前胡乙素、白花前胡素E、法卡林二醇、人参炔醇、柚皮芸香苷、橙皮苷、川陈皮素、橘红素的高效液相色谱（HPLC）一测多评（quantitative analysis of multi-components by single-marker，QAMS）方法，并结合聚类分析和主成分分析对参贝止咳颗粒进行综合质量评价。方法 采用Venusil XBP C₁₈色谱柱；乙腈-0.1%磷酸水溶液为流动相，梯度洗脱；检测波长分别为203 nm（检测重楼皂苷VII、VI、I）、321 nm（检测白花前胡甲素、白花前胡乙素和白花前胡素E）、254 nm（检测法卡林二醇和人参炔醇）和283 nm（检测柚皮芸香苷、橙皮苷、川陈皮素和橘红素）；以白花前胡甲素为内参物，建立重楼皂苷VII、VI、I及白花前胡乙素、白花前胡素E、法卡林二醇、人参炔醇、柚皮芸香苷、橙皮苷、川陈皮素和橘红素的相对校正因子（relative correction factor，RCF），利用RCF计算各成分含量并与外标法实测值进行比较，验证所建立的HPLC QAMS法的准确性和可行性；并采用SPSS 26.0统计软件对12批参贝止咳颗粒中12种成分定量测定结果进行聚类分析和主成分分析。结果 参贝止咳颗粒中12种成分线性范围良好（0.999 1 ≤ r ≤ 0.999 7）；重楼皂苷VII、VI、I及白花前胡乙素、白花前胡素E、法卡林二醇、人参炔醇、柚皮芸香苷、橙皮苷、川陈皮素和橘红素的RCF耐用性良好；QAMS法与外标法含量测定结果无显著性差异；聚类分析和主成分分析结果一致，12批参贝止咳颗粒聚为2类，主成分1~4是影响参贝止咳颗粒质量评价的主要因子。结论 以白花前胡甲素为内参物，建立的HPLC QAMS法可用于参贝止咳颗粒中多指标成分定量控制和综合质量评价。

Objective To establish a high performance liquid chromatography (HPLC) quantitative analysis of multi-components by single-marker (QAMS) method for the simultaneous determination of polyphyllin VII, VI, I, praeruptorin A, B, E, falcarindiol, panaxynol, narirutin, hesperidin, nobiletin and tangeretin in Shenbei Zhike Granules (SZG, 参贝止咳颗粒), and combine cluster analysis and principal component analysis to comprehensive evaluate the quality of SZG. Methods The chromatographic column was Venusil XBP C₁₈ column. The mobile phase was composed of acetonitrile-0.1% phosphoric acid in gradient elution. The detection wavelength were set at 203 nm for polyphyllin VII, VI, and I, 321 nm for praeruptorin A, B and E, 254 nm for falcarindiol and panaxynol, and 283 nm for narirutin, hesperidin, nobiletin and tangeretin. The relative correction factors (RCF) of polyphyllin VII, VI, I, praeruptorin B, E, falcarindiol, panaxynol, narirutin, hesperidin, nobiletin and tangeretin were established by HPLC method with praeruptorin A as internal reference, which was used to calculate the content of various constituents. The external standard method (ESM) was used to determine the contents of twelve components. The results of the two methods were compared, and the accuracy and feasibility of the established HPLC QAMS method was verified. The cluster analysis and principal component analysis of twelve components in twelve batches of SZG were carried out by SPSS 26.0 statistical software. Results The results showed that the twelve components had good linear relationship (0.999 1 ≤ r ≤ 0.999 7). The RCF of polyphyllin VII, VI, I, praeruptorin B, E, falcarindiol, panaxynol, narirutin, hesperidin, nobiletin and tangeretin had good durability. There was no significant difference between QAMS and ESM. The results of cluster analysis and principal component analysis were consistent. Twelve batches of samples were clustered into two categories, and the principal components 1-4 were the main factor affecting the quality evaluation of SZG. Conclusion The established HPLC QAMS method can be used for quantitative control and comprehensive quality evaluation of multiple index components in SZG.
