          摘   要  目的  为红花龙胆药材的质量控制提供参考依据。方法  以 52 批红花龙胆药材为研究对象,采用超高效液相色谱
         (UPLC)法,以《中药色谱指纹图谱相似度评价系统(2004A版)》对52批药材样品进行相似度评价,并测定药材中芒果苷含量,再
          进行化学计量学分析[聚类分析、主成分分析(PCA)和正交偏最小二乘法-判别分析(OPLS-DA)]。结果  建立了52批红花龙胆药
          材样品的 UPLC 指纹图谱,标定了 17 个共有峰,指认了其中 6 个,分别为马钱苷酸(1 号峰)、新芒果苷(3 号峰)、獐牙菜苦苷(5 号
          峰)、当药苷(6 号峰)、芒果苷(7 号峰)与异荭草苷(9 号峰)。52 批药材样品的相似度均大于 0.9;聚类分析结果显示,S1~S46、
          S48~S52聚为一类,S47单独为一类;PCA结果显示,前6个主成分的累计方差贡献率为82.928%;OPLS-DA结果显示,獐牙菜苦
          苷、芒果苷以及4、14、15、16号峰所代表的化学成分是影响红花龙胆药材质量差异的主要标志性成分。52批药材样品中芒果苷的
          含量在18.2~101.0 mg/g之间,大多符合2020年版《中国药典》规定。结论  所建立的UPLC指纹图谱和化学计量学分析方法结合
          芒果苷含量测定方法,能较为全面地评价红花龙胆药材的质量。

          ABSTRACT    OBJECTIVE To provide reference for quality control of Gentiana rhodantha. METHODS Taking 52 batches of G.
          rhodantha as subject, ultra-high performance liquid chromatography (UPLC) fingerprint was adopted. The similarity of 52 batches
          of  medicinal  materials  samples  was  evaluated  by  the  Similarity  Evaluation  System  for  Chromatographic  Fingerprints  of  Traditional
          Chinese  Medicine (2004A  edition);  the  content  of  mangiferin  was  determined;  chemometric  analyses  [cluster  analysis,  principal
          component  analysis (PCA)  and  orthogonal  partial  least  squares-discriminant  analysis (OPLS-DA)]  were  performed.  RESULTS
          UPLC  fingerprints  of  52  batches  of  G.  rhodantha  were  established,  17  common  peaks  were  identified,  and  6  of  them  were
          identified,  which  were  loganic  acid (peak  1),  neomangiferin (peak  3),  swertiamarin (peak  5),  dangyin (peak  6),  mangiferin
         (peak  7)  and  isoorientin (peak  9). The  similarities  of  52  batches  of  medicinal  materials  samples  were  all  greater  than  0.9;  cluster
          analysis  showed  that  S1-S46,  S48-S52  clustered  into  one  class,  and  S47  alone;  PCA  results  showed  that  the  cumulative  variance
          contribution rate of the first six principal components was 82.928%; OPLS-DA results showed that the corresponding components of
          swertiamarin, mangiferin and chemical composition represented by peak 4, 14, 15, 16 were the main iconic components affecting
          the quality differences of G. rhodantha medicinal materials. The contents of mangiferin in 52 batches of medicinal material samples
          ranged  from  18.2  to  101.0  mg/g,  mostly  in  accordance  with  2020  edition  of  Chinese  Pharmacopoeia.  CONCLUSIONS  The
          established  UPLC  fingerprint  and  chemometric  analysis  methods  combined  with  content  determination  method  of  mangiferin  can
          comprehensively evaluate the quality of G. rhodantha.
