        摘   要   目的 建立条芩与枯芩的指纹图谱,考察两者的抗炎活性差异。方法 采用高效液相色谱法建立5批条芩和5批枯芩的指
        纹图谱;采用 SIMCA 14.1 软件,以变量重要性投影(VIP)值>1 为标准筛选影响条芩和枯芩质量的差异标志物;以其对脂多糖
        (LPS)诱导的小鼠单核巨噬细胞(RAW264.7细胞)上清液中一氧化氮(NO)、白细胞介素6(IL-6)、IL-1β的抑制率为指标,评价条芩
        和枯芩的抗炎活性并计算其抑制 NO 的半数有效浓度(EC50 );采用灰色关联分析谱效关系;以 50 μg/mL 质量浓度下各组细胞的
        NO、IL-1β、IL-6 抑制率为指标,采用 SPSS 26.0 软件进行聚类分析。结果 5 批条芩和 5 批枯芩共有 15 个共有峰,相似度均大于
        0.990。共有8个峰的VIP值>1,依次为峰14、12、15、6、10、13、11、4。在50 μg/mL质量浓度下,枯芩提取物对NO、IL-6、IL-1β的抑
        制率及平均 EC50 分别为 62.14%~71.13%、3.32%~18.38%、93.12%~95.47%、25.35 μg/mL,条芩提取物分别为 39.52%~
        50.19%、6.21%~22.55%、94.10%~96.44%、58.63 μg/mL;枯芩提取物的平均NO抑制率显著高于条芩提取物,平均EC50、IL-6抑
        制率均显著低于条芩提取物(P<0.05);两者平均IL-1β抑制率比较差异无统计学意义(P>0.05)。峰2~3、5~8、10~11与NO抑
        制率的关联度均大于0.8,峰2、5、8~9与IL-1β抑制率的关联度均大于0.9,15个共有峰与IL-6抑制率的关联度均小于0.8。10批样
        品可聚为2类,K1~K5为一类,T12~T16为一类。结论 在50 µg/mL质量浓度下,枯芩提取物对NO的抑制作用强于条芩提取物,
        对IL-6的抑制作用弱于条芩提取物,对IL-1β的抑制作用与条芩提取物相当;初步确定峰6、10~11对应成分为条芩与枯芩抗炎活
        性差异的主要化学成分。

        ABSTRACT    OBJECTIVE To establish the fingerprints of pith-nodecayed and pith-decayed Scutellaria baicalensis,and to
        investigate the difference of their anti-inflammatory activities. METHODS HPLC method was adopted to establish the fingerprints
        of 5 batches of pith-nodecayed S. baicalensis and 5 batches of pith-decayed S. baicalensis. SIMCA 14.1 software was adopted to
        screen the markers of weight difference between pith-decayed S. baicalensis and pith-nodecayed S. baicalensis,using variable
        importance in projection (VIP) >1 as standard. Using the inhibitory rates of NO,IL-6 and IL-1 β in supernatant of lipopo-
        lysaccharide(LPS)-induced monocyte macrophages(RAW264.7 cells)as indexes,the anti-inflammatory activities of pith-decayed
        and pith-nodecayed S. baicalensis were evaluated and median effective concentration (EC50 ) of NO were calculated. The gray
        correlation method was used for spectrum-effect relationship analysis;SPSS 26.0 software was used for cluster analysis using the
        inhibitory rates of NO,IL-6 and IL-1β in cells at the concentration of 50 μg/mL. RESULTS There were 15 common peaks in 5
                                                            batches of pith-nodecayed S. baicalensis and 5 batches of
