          摘   要  目的  建立不同产地苦参药材的指纹图谱,筛选差异性成分,并进行含量测定。方法  采用《中药色谱指纹图谱相似度评
          价系统(2012 版)》建立 12 批苦参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;采用 SIMCA 14.1 和
          SPSS 23.0软件进行化学模式识别分析[聚类分析(CA)、主成分分析(PCA)、正交偏最小二乘法-判别分析(OPLS-DA)],并以变量
          重要性投影(VIP)值>1为标准筛选影响苦参药材质量的差异性成分;采用同一HPLC法测定4种差异性成分的含量。结果  12批
          苦参药材的指纹图谱中共有17个共有峰,相似度均大于0.96;共指认了6个共有峰,分别为氧化苦参碱(峰1)、氧化槐果碱(峰2)、
          苦参碱(峰10)、三叶豆紫檀苷(峰14)、苦参酮(峰16)、降苦参酮(峰17)。CA、PCA、OPLS-DA结果显示,12批苦参药材可按不同
          产地聚为3类:S1~S7(陕西商州区)聚为一类,S8~S10(河南伊川县)聚为一类,S11~S12(内蒙古赤峰市)聚为一类。苦参碱、降
          苦参酮、苦参酮、氧化槐果碱以及峰11、峰9所代表的化学成分的VIP值均大于1。12批苦参药材中苦参碱、降苦参酮、苦参酮、氧
          化槐果碱的含量分别为2.65~4.93、1.54~3.44、9.63~12.94、5.08~6.10 mg/g。结论  本研究成功建立了苦参药材的HPLC指纹图
          谱,并结合化学模式识别分析筛选出6种差异性成分,可为该药材的质量控制提供参考。

          ABSTRACT    OBJECTIVE  To  establish  the  fingerprint  of  Sophora  flavescens,  and  to  screen  differential  components  and
          determine  their  contents. METHODS  HPLC  fingerprints  of  12  batches  of  S.  flavescens  were  established  by  using  Similarity
          Evaluation  System  of  Chromatographic  Fingerprints  of  TCM (2012  edition);  common  peaks  were  identified  and  their  similarities
          were  evaluated.  Chemical  pattern  recognition  analysis  [cluster  analysis (CA),principal  component  analysis (PCA)  and  orthogonal
          partial least squares-discriminant analysis(OPLS-DA)] were performed with SIMCA 14.1 and SPSS 23.0 software, and differential
          components  which  influenced  the  quality  of  S.  flavescens  were  screen  with  variable  importance  in  the  projection(VIP)>1  as
          standard.  Meanwhile,  the  contents  of  4  kinds  of  differential  components  were  determined  by  the  same  HPLC  method. RESULTS
          There  were  17  common  peaks  in  the  fingerprints  of  12  batches  of  S.  flavescens,and  their  similarities  were  all  higher  than  0.96. A
          total  of  6  common  peaks  were  identified,  i.e.  oxymatrine (peak  1),  oxysophocarpine (peak  2),  matrine (peak  10),  trifolirhizin
         (peak 14), kurarinone (peak 16) and norkurarinone (peak 17). Results of CA, PCA and OPLS-DA showed that 12 batches of S.
          flavescens  were  divided  into  3  categories  according  to  producing  area,  i.e.  S1-S7 (Shangzhou  District  of  Shaanxi  Province)  were
          grouped  into  one  category,  S8-S10 (Yichuan  County  of  Henan  Province)  into  one  category  and  S11-S12 (Chifeng  City  of  Inner
          Mongolia)  into  one  category.  VIPs  of  matrine,  norkurarinone,  kurarinone  and  oxysophocarpine  and  the  chemical  components
          represented  by  peak  11  and  9  were  all  greater  than  1. The  contents  of  matrine,  norkurarinone,  kurarinone  and  oxysophocarpine  in
          12  batches  of  S.  flavescens  were  2.65-4.93,  1.54-3.44,  9.63-12.94  and  5.08-6.10  mg/g,  respectively.  CONCLUSIONS  HPLC
                                                              fingerprint  of  S.  flavescens  is  established  successfully  in  the
