          摘   要  目的  探寻不同基原大黄饮片滋味、气味和挥发性有机物的差异,对大黄饮片进行基原辨识。方法  采用电子舌、电子鼻
          和气相-离子迁移谱(GC-IMS)技术,对不同基原大黄饮片间的滋味、气味和挥发性有机物进行对比分析,运用主成分分析(PCA)、
          偏最小二乘法判别分析(PLS-DA)、正交偏最小二乘法判别分析(OPLS-DA)、Fisher判别等方法对大黄饮片基原进行辨识研究并
          建立基原判别标准。结果  3种基原大黄饮片的滋味差异主要表现在苦味、涩味以及苦和涩的回味,气味的差异主要表现在无机
          硫化物、芳香成分有机硫化物、甲烷等短链烷烃、醇醚醛酮类化合物以及氮氧化合物,差异性挥发性有机物主要为醇醛酮酸类成
          分,并且8批样品均能很好地聚集为3类。根据差异性挥发物质之间的峰强度比值可有效辨识3种大黄饮片,如当2-乙酰基呋喃
          峰强度是异丁酸[二聚体]峰强度的3~19倍时为药用大黄。结论  本研究建立的判别模型以及特征挥发性物质峰强度判别标准可
          用于大黄饮片基原的鉴别。

          ABSTRACT    OBJECTIVE  To  investigate  the  variations  in  taste,  aroma  and  volatile  organic  compounds  of  Rhei  Radix  et
          Rhizoma  decoction  pieces  derived  from  different  sources,  and  to  identify  their  origins.  METHODS  The  flavor,  odor  and  volatile
          organic  compounds  of  Rhei  Radix  et  Rhizoma  decoction  pieces  from  different  sources  were  compared  and  analyzed  by  using
          electronic  tongue,  electronic  nose,  and  gas  chromatography-ion  mobility  spectrometry (GC-IMS).  Principal  component  analysis
         (PCA),  partial  least  squares-discriminant  analysis (PLS-DA),  orthogonal  partial  least  squares  discriminant  analysis (OPLS-DA)
          and Fisher discriminant analysis were employed to identify the origins of Rhei Radix et Rhizoma decoction pieces and establish the
          basis  discrimination  criteria.  RESULTS  The  differences  in  taste  of  Rhei  Radix  et  Rhizoma  decoction  pieces  from  3  origins  were
          primarily  characterized  by  bitterness,  astringency,  and  bitter-astringent  aftertaste.  In  terms  of  smell,  variations  were  mainly
          observed in inorganic sulfides, organic sulfides containing aromatic components, methane and other short-chain alkanes, alcohols,
          ethers,  aldehydes  and  ketones,  as  well  as  nitrogen  oxides.  Differentially  volatile  organic  compounds  mainly  consisted  of  alcohols,
          aldehydes  and  ketones.  Furthermore,  the  samples  from  8  batches  could  be  effectively  classified  into  3  categories.Three  types  of
          Rhei  Radix  et  Rhizoma  decoction  pieces  can  be  effectivily  identified  based  on  the  peak  intensity  ratio  between  volatile  substances.
          For example, when the peak intensity of 2-acetylfuran was 3-19 times that of isobutyric acid [dimer], it was considered as Rheum
                                                              officinale  Baill.  CONCLUSIONS  The  discriminant  models
