        摘   要   目的:建立金钱草药材的超高效液相色谱(UPLC)特征指纹图谱,同时测定其中3种有效成分的含量,并综合评价不同产
        地金钱草的整体质量。方法:采用UPLC法建立10批金钱草全草、茎及叶的特征指纹图谱并测定山柰酚-3-O-芸香糖苷、槲皮素、
        山柰素的含量。色谱柱为 Waters CORTECS UPLC T3,流动相为乙腈-0.2%磷酸水溶液(梯度洗脱),检测波长为 364 nm,柱温为
        30 ℃,流速为0.2 mL/min,进样量为1 µL。采用《中药色谱特征图谱相似度评价系统(2012版)》进行相似度评价,确定共有峰;以
        山柰酚-3-O-芸香糖苷、槲皮素、山柰素、总灰分、酸不溶性灰分、二氧化硫残留量及醇溶性浸出物为指标,采用熵权优劣解距离法
        (TOPSIS)对金钱草药材的整体质量进行综合评价。结果:10批金钱草全草、茎及叶共有7个共有峰,指认了其中3个峰分别为山
        柰酚-3-O-芸香糖苷、槲皮素、山柰素。同一部位不同批次金钱草全草的相似度均不低于0.830;同一批次金钱草茎与叶的相似度为
        0.504~0.859,全草与茎的相似度为0.593~0.904,全草与叶的相似度为0.885~0.995。山柰酚-3-O-芸香糖苷、槲皮素、山柰素检测质
        量浓度的线性范围分别为0.392 0~39.197 0、0.397 0~39.703 4、0.380 9~38.093 0 μg/mL(r均大于0.999 0);精密度、稳定性、重复
        性试验的 RSD 均小于 2%;加样回收率分别为 96.43%(RSD=0.63%,n=9)、100.32%(RSD=0.46%,n=9)、101.80%(RSD=
        0.32%,n=9)。金钱草中上述 3 种成分的含量分别为 0.006 3%~0.041 1%、0.002 9%~0.008 6%、0.004 4%~0.017 5%(茎),
        0.024 8%~0.290 5%、0.000 9%~0.009 0%、0.001 3%~0.012 4%(叶),0.007 9%~0.118 0%、0.001 5%~0.008 8%、0.002 8%~
        0.012 5%(全草)。不同产地样品间3种成分含量比较,差异均无统计学意义(P>0.05);金钱草不同部位中山柰酚-3-O-芸香糖的
        含量大小顺序依次为叶>全草>茎,槲皮素与山柰素的含量大多以茎中含量较高。熵权TOPSIS法结果显示,四川省中江县、双流
        县以及重庆市石柱县产金钱草的最优解欧氏贴近度均值分别为0.446、0.512、0.287。结论:所建特征指纹图谱和含量测定方法稳
        定、可行,结合熵权TOPSIS法所建的多指标评价模型可用于金钱草药材质量的综合评价;四川省产金钱草药材质量较优。

        ABSTRACT    OBJECTIVE:To establish UPLC characteristics fingerprints of Lysimachia christinae,and to simultaneously
        determine 3 effective components and to comprehensively evaluate the quality of L. christinae from different production areas.
        METHODS:UPLC method was adopted to establish characteristics fingerprint of the whole plant,stem and leaves of 10 batches of
        L. christinae,and determine the contents of kaemperfol-3-O-rutinoside,quercetin,kaemperfol. The determination was performed
        on Waters CORTECS UPLC T3 column with mobile phase consisted of acetonitrile-0.2% phosphoric acid aqueous solution
        (gradient elution)at the flow rate of 0.2 mL/min. The detection wavelength was set at 364 nm,and column temperature was 30 ℃.
        The sample size was 1 µL. Similarity Evaluation System for TCM Chromatographic Fingerprint(2012 edition) was adopted to
        evaluate its similarity, and common peaks were confirmed. Using the contents of kaemperfol-3-O-rutinoside, quercetin,
        kaemperfol,total ash,acid-insoluble ash and sulfur dioxide residue,the ethanol-soluble extract as index,entropy weight TOPSIS
        was used to evaluate the overall quality of L. christinae comprehensively. RESULTS:There were 7 common peaks in the whole
        plant,stem and leaves of 10 batches of L. christinae,among which 3 peaks were identified as kaemperfol-3-O-rutinoside,
                                                            quercetin and kaemperfol. The similarity of same part in the
