          摘   要  目的  分析浮小麦和小麦的成分差异,为二者的鉴定及质量控制提供参考。方法  收集20批浮小麦和3批小麦药材,采用
          高效液相色谱法,利用《中药色谱指纹图谱相似度评价系统》(2012版)绘制指纹图谱并进行相似度评价,应用聚类分析(CA)、主成
          分分析(PCA)和正交偏最小二乘判别分析(OPLS-DA)对不同产地浮小麦及小麦样品进行差异分析,筛选差异成分,并测定浮小
          麦和小麦中6个指认成分的含量。结果  浮小麦指纹图谱的相似度为0.928~0.996,小麦与浮小麦的相似度为0.761~0.773;在浮
          小麦和小麦中共标定19个共有峰,指认出了6个成分,分别为亚麻酸、亚油酸、5-十七烷基间苯二酚、5-十九烷基间苯二酚、5-二十
          一烷基间苯二酚和5-二十三烷基间苯二酚。CA、PCA结果显示,浮小麦和小麦能明显区分;产地为安徽的浮小麦的分布较为集
          中。OPLS-DA结果显示,亚麻酸、亚油酸及其他6个未知化合物为浮小麦和小麦的差异成分。浮小麦中上述6个指认成分的平均
          含量分别为0.100 9、1.094 0、0.005 1、0.030 9、0.098 2、0.024 8 mg/g,且浮小麦中亚麻酸、亚油酸的含量均显著高于小麦(P<0.05)。
          结论  所建定性、定量测定方法操作简单、结果可靠,可用于浮小麦和小麦的鉴别及质量评价。亚麻酸、亚油酸等差异成分可为浮

          ABSTRACT    OBJECTIVE To analyze the compositional differences between Fructus Tritici Levis and Triticum aestivum, and to
          provide  reference  for  identification  and  quality  control  of  both.  METHODS  Twenty  batches  of  Fructus  Tritici  Levis  and  three
          batches  of  T.  aestivum  were  collected,  and  their  fingerprints  were  acquired  by  high-performance  liquid  chromatography  and  the
          similarities were evaluated by the Evaluation System of Similarity of Chromatographic Fingerprints of Traditional Chinese Medicine
         (2012  version).  Cluster  analysis (CA),  principal  component  analysis (PCA)  and  orthogonal  partial  least  squares-discriminant
          analysis (OPLS-DA) were performed to analyze the difference of Fructus Tritici Levis and T. aestivum from different regions, and
          the  differential  components  were  screened.  The  contents  of  the  six  identified  components  in  Fructus  Tritici  Levis  and  T.  aestivum
          were  determined.  RESULTS  The  similarities  of  the  fingerprints  of  Fructus  Tritici  Levis  ranged  from  0.928  to  0.996,  and  the
          relative  similarities  of  T.  aestivum  with  Fructus  Tritici  Levis  ranged  from  0.761  to  0.773.  A  total  of  19  common  peaks  were
          calibrated,  and  six  components  including  linolenic  acid,  linoleic  acid,  5-heptadecylresorcinol,  5-nonadodecylresorcinol,  5-
          heneicosylresorcinol,  and  5-tricosylresorcinol  were  identified. The  results  of  CA  and  PCA  showed  that  Fructus Tritici  Levis  and T.
          aestivum  could  be  clearly  distinguished;  the  distribution  of  Fructus  Tritici  Levis  from Anhui  province  was  relatively  concentrated.
                                                              The  results  of  OPLS-DA  showed  that  linolenic  acid,  linoleic
