          认共有峰并进行相似度评价,同时确认每个共有峰的饮片归属。运用化学模式识别方法中的层次聚类分析(HCA)、主成分分析
         (PCA)对13批样品(S1~S13)进行分类,并采用正交偏最小二乘-判别分析(OPLS-DA)来识别导致不同批次样品间差异的关键性
          成分。结果  所建UPLC方法精密度、重复性、稳定性的RSD均不大于4.4%。在13批精天颗粒指纹图谱中共标定出25个共有峰;
          通过与对照指纹图谱比对,指认了其中10个共有峰,分别为3号峰(5-羟甲基糠醛)、5号峰(红景天苷)、8号峰(绿原酸)、15号峰
         (肉桂酸)、19号峰(芦荟大黄素)、20号峰(甘草酸铵)、21号峰(大黄酸)、23号峰(大黄素)、24号峰(甘草次酸)、25号峰(大黄酚)。
          13批样品指纹图谱的相似度为0.955~0.996。HCA结果显示,13批样品可聚为3类,其中S1、S5、S7、S11~S13为一类,S4、S6为
          一类,S2、S3、S8~S10为一类。PCA结果显示,主成分1~7的累计方差贡献率为92.666%。OPLS-DA进一步确定了13个差异性
          成分,这些成分主要来源于酒黄精、红景天、熟大黄和炙甘草等。结论  所建立的精天颗粒UPLC指纹图谱方法简便、稳定、重复性
          良好,结合化学模式识别方法能有效揭示精天颗粒不同批次间的整体质量差异。方中酒黄精、红景天、熟大黄、穿山龙、猪苓、桂
          枝、炙甘草的质量是影响精天颗粒整体质量的关键。

          ABSTRACT    OBJECTIVE  To  establish  the  ultra-high  performance  liquid  chromatography (UPLC)  fingerprint  of  Jingtian
          granule,  and  to  evaluate  its  quality  by  chemical  pattern  recognition.  METHODS  Luna   Omega  Polar  C18  column (150  mm×2.1
                                                                             ®
          mm,  1.6  μm)  was  used  as  the  chromatographic  column,  and  acetonitrile-0.2%  phosphoric  acid  solution  was  used  as  the  mobile
          phase  for  gradient  elution. The  flow  rate  was  0.2  mL/min,  the  column  temperature  was  30  ℃,  and  the  detection  wavelength  was
          265 nm. With peak 16 as the reference peak, the UPLC fingerprint of Jingtian granule was established by the Similarity Evaluation
          System  of  Chromatographic  Fingerprint  of  Traditional  Chinese  Medicine (2012  edition).  The  common  peaks  were  identified,  the
          similarity evaluation was carried out, and the ownership of each common peak was confirmed. Hierarchical cluster analysis (HCA)
          and principal component analysis (PCA) in chemical pattern recognition methods were used to classify 13 batches of samples (S1-
          S13),  and  orthogonal  partial  least  squares-discriminant  analysis (OPLS-DA)  was  used  to  identify  the  key  components  of  the
          differences  between  different  batches  of  samples.  RESULTS  RSDs  of  precision,  repeatability  and  stability  of  the  UPLC  method
          were  not  more  than  4.4%. A  total  of  25  common  peaks  were  identified  in  the  fingerprints  of  13  batches  of  Jingtian  granules.  By
