        摘   要   目的:建立芩连润肺汤的指纹图谱,测定其中11种成分的含量,并进行聚类分析、正交偏最小二乘判别法(OPLS -DA)分
        析。方法:采用高效液相色谱法(HPLC)。色谱柱为ZORBAX Eclipse Plus C18,流动相为乙腈-0.05%磷酸溶液(梯度洗脱),检测波

        RSD 均小于 2%;平均加样回收率为 95.81%~100.29%(RSD 为 0.43%~1.73%,n=6);含量分别为 8.924 4~12.820 8、0.352 2~
        0.868 7、0.435 6~0.711 2、0.389 8~1.309 0、0.335 8~0.530 1、1.680 5~4.542 3、0.701 8~1.584 2、2.240 2~5.442 5、2.351 0~5.558 9、
        0.106 0~0.182 2、0.076 8~0.128 9 mg/g。聚类分析结果显示,当类间距为10时,10批样品可聚为两类,S1~S3聚为一类、S4~S10
        聚为一类;当类间距为5时,第2类又可聚为两类,S6、S7、S9聚为一类,S4、S5、S8、S10聚为一类。OPLS-DA分析结果显示,S6、S7、
        S9位于得分图的上方,S4、S5、S8、S10位于得分图的左下侧,S1~S3位于得分图的右下侧,与聚类分析结果一致;黄芩苷、鸢尾苷、
        连翘酯苷A、黄芩素、汉黄芩苷的变量重要性投影值均大于1。结论:所建指纹图谱、含量测定方法的精密度较高、稳定性较好,结
        合多元统计分析 可用于芩连润肺汤的质量控制。黄芩苷等5种成分为影响芩连润肺汤的质量标志物。

        ABSTRACT    OBJECTIVE:To establish the fingerprint of Qinlian runfei decoction,determine the contents of 11 components,
        and conduct cluster analysis and orthogonal partial least squares discriminant analysis(OPLS-DA). METHODS:HPLC method
        was used. The determination was performed on ZORBAX Eclipse Plus C18 column with mobile phase consisted of acetonitrile-
        0.05% phosphoric acid solution(gradient elution)at the flow rate of 1.0 mL/min. The detection wavelength was set at 260 nm,
        and column temperature was 30 ℃. The sample size was 10 μL. Using wogonoside as reference,HPLC fingerprints of 10 batches
        of Qinlian runfei decoction were drawn and the similarity evaluation was conducted with Similarity Evaluation System of TCM
        Chromatographic Fingerprint(2012 edition),the common peaks were also confirmed;the contents of 11 components in Qinlian
        runfei decoction were determined by the same method. SPSS 21.0 software was used for cluster analysis,and SIMCA 14.0 software
                                                            was used for OPLS-DA to screen marker components affecting
