        摘   要   目的 建立不同产地茶芎的指纹图谱,筛选差异性成分并测定其含量。方法 以Z-藁本内酯为参照,采用《中药色谱指纹图
        谱相似度评价系统(2012版)》建立12批茶芎药材的高效液相色谱(HPLC)指纹图谱,指认共有峰并进行相似度评价;进行聚类分
        析(CA)、主成分分析(PCA)和正交偏最小二乘-判别分析(OPLS-DA),以变量重要性投影(VIP)>1为标准筛选影响药材质量的
        差异性成分;采用同一 HPLC 法测定上述差异性成分的含量。结果 12 批茶芎药材指纹图谱共有 17 个共有峰,相似度为 0.989~
        1.000;共指认了7个共有峰,分别为绿原酸(1号峰)、阿魏酸(2号峰)、洋川芎内酯Ⅰ(7号峰)、阿魏酸松柏酯(9号峰)、E-藁本内酯
        (13号峰)、洋川芎内酯A(14号峰)、Z-藁本内酯(17号峰)。CA结果显示,12批茶芎药材可分为3类,S1~S5(武宁茶芎)聚为一类,
        S6~S8(瑞昌茶芎)聚为一类,S9~S12(德安茶芎)聚为一类;2、13、14、17号峰(分别对应阿魏酸、E-藁本内酯、洋川芎内酯A、Z-藁
        本内酯)的VIP均大于1。S1~S5、S6~S8、S9~S12样品中,阿魏酸的含量分别为0.488~0.533、0.603~0.658、0.415~0.433 mg/g,洋
        川芎内酯 A 分别为 1.184~1.295、1.450~1.588、1.307~1.377 mg/g,E-藁本内酯分别为 0.118~0.125、0.130~0.135、0.223~0.229
        mg/g,Z-藁本内酯分别为7.200~7.681、8.076~8.643、4.508~4.996 mg/g,两两比较差异均有统计学意义(P<0.05)。结论 所建指
        纹图谱操作简便、准确,结合多元统计分析可用于评价不同产地茶芎的整体质量。阿魏酸、洋川芎内酯A、Z-藁本内酯、E-藁本内
        酯可能是影响不同产地茶芎药材质量的差异性成分,且前3种成分含量均以瑞昌茶芎最高,E-藁本内酯含量以德安茶芎最高。

        ABSTRACT     OBJECTIVE To establish the fingerprints of Ligusticum sinense from different habitats, screen differential
        components and determine their contents. METHODS Using Z-ligustilide as reference,HPLC fingerprints of 12 batches of L.
        sinense were established by using Similarity Evaluation System of Chromatographic Fingerprints of TCM(2012 edition);common
        peaks were identified and their similarities were evaluated. Cluster analysis (CA),principal component analysis (PCA) and
        orthogonal partial least squares-discriminant analysis(OPLS-DA)were performed to screen differential components with variable
        importance in the projection(VIP)>1 as standard;meanwhile,the contents of above differential components were determined by
        the same HPLC method. RESULTS There were 17 common peaks in the fingerprints of 12 batches of L. sinense,and their
        similarities ranged 0.989-1.000. A total of 9 common peaks were identified,i.e. chlorogenic acid(peak 1),ferulic acid(peak 2),
        senkyunolide Ⅰ(peak 7),coniferyl ferulate(peak 9),E-ligustilide(peak 13),senkyunolide A(peak 14),Z-ligustilide(peak
        17). CA results showed that 12 batches of L. sinense were divided into 3 categories,S1-S5(Wuning)were clustered into one
        category,S6-S8(Ruichang)were clustered into one category,S9-S12(De’an)were clustered into one category;the VIP values
        of peaks 2,13,14 and 17(corresponding to ferulic acid,E-ligustilide,senkyunolide A,and Z-ligustilide respectively)were all
        greater than 1,respectively. In S1-S5,S6-S8 and S9-S12 samples,the contents of ferulic acid were 0.488-0.533,0.603-0.658 and
        0.415-0.433 mg/g,respectively;senkyunolide A were 1.184-1.295,1.450-1.588 and 1.307-1.377 mg/g,respectively;E-ligustilide
        were 0.118-0.125,0.130-0.135 and 0.223-0.229 mg/g,respectively;Z-ligustilide were 7.200-7.681,8.076-8.643 and 4.508-4.996 mg/g,
                                                            respectively;the differences between two groups were statisti-
