          摘  要  目的  综合评价青黛的质量,为青黛质量控制提供参考。方法  采用超高效液相色谱-三重四极杆串联质谱(UPLC-MS/
          MS)法同时测定不同产地青黛中6个吲哚生物碱(靛蓝、靛玉红、靛红、色胺酮、吲哚、吲哚-3-甲醛)的含量,采用聚类分析、主成分
          分析、偏最小二乘法-判别分析(PLS-DA)对不同产地的青黛质量进行评价。结果  不同产地青黛中靛蓝、靛玉红、靛红、色胺酮、吲
          哚、吲哚-3-甲醛含量的范围分别为 20 320.83~26 585.01、1 327.69~3 102.25、141.69~894.50、2.17~5.27、2.14~5.93、1.69~4.34
          μg/g。聚类分析将不同产地的青黛聚为 2 类,S1、S2、S4、S6、S7、S9、S10 号样品聚为Ⅰ类,S3、S5、S8、S11、S12 号样品聚为Ⅱ类。
          用3个主成分对不同产地青黛进行评价,结果显示,Ⅰ类样品得分较高,质量较优,Ⅱ类样品得分较低,质量较差。PLS-DA结果显
          示,靛蓝、靛玉红、色胺酮、靛红是体现青黛质量差异的主要物质。结论  不同产地的青黛质量差异较大,且同一产地不同批次的青
          黛质量不稳定。本文所建立的青黛质量评价方法稳定可靠,可为青黛的质量控制提供依据。

          ABSTRACT   OBJECTIVE To evaluate the quality of Indigo Naturalis, and to provide reference for the quality control of Indigo
          Naturalis.  METHODS  UPLC-MS/MS  method  was  used  to  determine  the  contents  of  6  indole  alkaloids (indigo,  indirubin,  isatin,
          tryptanthrin,  indole  and  indole-3-carboxaldehyde)  in  Indigo  Naturalis  from  different  origins.  Cluster  analysis,  principal  component
          analysis  and  partial  least  squares-discriminant  analysis (PLS-DA)  were  used  to  evaluate  the  quality  of  Indigo  Naturalis  from
          different  origins.  RESULTS  The  contents  of  indigo,  indirubin,  isatin,  tryptanthrin,  indole  and  indole-3-carboxaldehyde  in  Indigo
          Naturalis from different origins were 20 320.83-26 585.01, 1 327.69-3 102.25, 141.69-894.50, 2.17-5.27, 2.14-5.93 and 1.69-4.34
          μg/g,respectively. The Indigo Naturalis from different areas were clustered into two categories by cluster analysis. Samples S1, S2,

          S4, S6, S7, S9 and S10 were clustered into category Ⅰ, and samples S3, S5, S8, S11 and S12 were clustered into category Ⅱ.
          Indigo  Naturalis  from  different  origins  was  evaluated  with  3  principal  components.  The  results  showed  that  category  Ⅰ  sample
          scored  higher  and  had  better  quality,  while  category  Ⅱ  sample  scored  lower  and  had  worse  quality.  PLS-DA  showed  that  indigo,
          indirubin,  tryptanthrin  and  isatin  were  the  main  substances  that  reflected  the  quality  difference  of  Indigo  Naturalis.
          CONCLUSIONS The quality of Indigo Naturalis from different origins is different, and the quality of Indigo Naturalis of different
          batches  from  the  same  area  is  not  stable.  The  quality  evaluation  method  of  Indigo  Naturalis  established  in  this  paper  is  stable  and
          reliable, which can provide a basis for the quality control of Indigo Naturalis.
