          摘  要  目的  研究半夏地上部分(非药用的茎和叶部分)的活性成分和镇咳作用,并与半夏地下部分(药用的地下块茎部分)进行
          对比,为半夏综合利用和产品开发提供科学依据。方法  采用薄层色谱(TLC)法、气相色谱(GC)法、高效液相色谱(HPLC)法和超
          高效液相色谱串联质谱(UPLC-MS/MS)法对半夏地上和地下部分的氨基酸类、挥发油类、总黄酮类、有机酸类成分进行定性和定
          量分析;通过浓氨水引咳实验,对半夏地上和地下部分的镇咳作用进行对比研究。结果  TLC结果显示,在与半夏对照药材以及精
          氨酸、丙氨酸、缬氨酸、亮氨酸、芦丁对照品色谱图相应的位置上,半夏地上和地下部分均显相同颜色的斑点;GC分析结果显示,半
          夏地上和地下部分挥发油特征图谱的相似度为0.767;HPLC和UPLC-MS/MS分析结果显示,与半夏地下部分相比,地上部分中琥
          珀酸、槲皮素、山柰酚和异鼠李素的含量分别高了0.15%、0.15%、0.09%、0.03%,天门冬氨酸含量低了2.5 mg/g。药效结果显示,与
          模型对照组比较,各给药组大鼠的咳嗽潜伏期均显著延长(P<0.05),3 min内咳嗽次数均显著减少(P<0.05),且各给药组大鼠3
          min内咳嗽次数差异无统计学意义(P>0.05)。结论  半夏地上部分的氨基酸类、挥发油类、总黄酮类化合物组成与半夏地下部分
          相似,琥珀酸、槲皮素、山柰酚、异鼠李素含量高于半夏地下部分,天门冬氨酸含量低于地下部分;半夏地上部分可延长大鼠咳嗽潜
          伏期,减少咳嗽次数,具有一定的镇咳效果,但作用比地下部分稍弱。

          ABSTRACT   OBJECTIVE  To  study  active  components  and  antitussive  effect  of  aboveground  part  of  Pinellia  ternata (non-
          medicinal stems and leaves), and compare them with the underground part of P. ternata (medicinal underground tubers), providing
          scientific basis for the comprehensive utilization and product development of P. ternata. METHODS TLC, GC, HPLC and UPLC-
          MS/MS were used for qualitative and quantitative analysis of amino acids, volatile oil, total flavonoids and succinic acid from the
          aboveground  and  underground  parts  of  P.  ternata.  The  antitussive  effects  of  the  aboveground  and  underground  parts  of  P.  ternata
          were  compared  and  studied  through  cough  inducing  experiment  with  concentrated  ammonia  water.  RESULTS  Results  of  TLC
          showed  that  at  the  corresponding  positions  on  the  chromatograms  of  the  reference  substances  of  P.  ternata,  and  arginine,  alanine,
          valine, leucine and rutin control, the aboveground and underground parts of P. ternata showed  spots  of the same color. Results of
          GC  showed  that  the  similarity  among  characteristic  chromatograms  of  volatile  oil  from  aboveground  and  underground  parts  of  P.
                                                             ternata was 0.767; results of HPLC and UPLC-MS/MS showed
