          摘  要  目的  以野黄芩苷、迷迭香酸为内参物,建立同时测定紫苏叶中 6 种黄酮类及 2 种酚酸类成分含量的一测多评(QAMS)
          法,并采用该法测定20批不同产地紫苏叶样品中8种成分的含量。方法  以野黄芩苷为内参物计算野黄芩素-7-O-二葡萄糖醛酸
          苷、木犀草素-7-O-二葡萄糖醛酸苷、芹菜素-7-O-二葡萄糖醛酸苷、木犀草素-7-O-β-D-葡萄糖醛酸苷、芹菜素-7-O-葡萄糖醛酸苷的
          相对校正因子,以迷迭香酸为内参物计算咖啡酸的相对校正因子,采用QAMS法测定样品中各成分的含量,并与外标法检测结果
          进行比较。结果  上述8种成分在各自质量浓度范围内线性关系良好(r≥0.999 0),平均加样回收率为95.60%~102.15%,RSD为
          0.72%~2.70%(n=6)。该方法的精密度、重复性、稳定性均良好(RSD<2.50%,n=6)。不同仪器和色谱柱、柱温、流速、甲酸体积
          分数对所得相对校正因子的影响较小(RSD<3%,n=3)。与外标法比较,除ZS12批次样品中的咖啡酸外,其余各批次样品中各
          成分的含量均无明显差异(RE绝对值<5%,n=2)。不同产地紫苏叶样品中6种黄酮类成分的含量存在一定差异,而上述黄酮类
          成分的总含量无明显差异;不同产地紫苏叶中2种酚酸类成分的含量及其总含量具有明显差异。结论  所建QAMS法可同时测定
          紫苏叶药材中6种黄酮类及2种酚酸类成分的含量,方法检测方便、准确度高且成本较低,可用于紫苏叶药材的质量控制。不同产
          地紫苏叶药材中黄酮类及酚酸类成分的含量存在一定差异,可为紫苏叶药材产地的优选提供参考依据。

          ABSTRACT   OBJECTIVE  To  establish  a  quantitative  analysis  of  multi-components  by  single-marker (QAMS)  method  for
          simultaneous  determination  of  six  flavonoids  and  two  phenolic  acids  in  Perilla  frutescens  leaves  using  scutellarin  and  rosmarinic
          acid  as  internal  reference  substances,  and  apply  this  method  to  determine  the  contents  of  eight  components  in  20  batches  of  P.
          frutescens  leaves  samples  from  different  regions.  METHODS  Scutellarin  served  as  the  internal  reference  to  calculate  relative
          correction  factors (RCFs)  for  scutellarin-7-O-diglucuronide,  luteolin-7-O-diglucuronide,  apigenin-7-O-diglucuronide,  luteolin-7-O-
          β-D-glucuronide  and  apigenin-7-O-glucuronide.  Rosmarinic  acid  was  employed  as  the  internal  reference  to  determine  the  RCF  for
          caffeic acid. The contents of the above flavonoids and phenolic acids were calculated with QAMS, and compared with the results of
          external standard method. RESULTS The eight analytes demonstrated excellent linearity within their respective concentration ranges
         (r≥0.999  0).  The  mean  recovery  rates  for  spiked  samples  ranged  from  95.60%  to  102.15%,  with  relative  standard  deviations
         (RSDs)  of  0.72%  to  2.70% (n=6).  The  method  exhibited  good  precision,  repeatability,  and  stability (RSD<2.50%,  n=6).
          Variations  in  instruments,  columns,  column  temperature,  flow  rate,  and  formic  acid  volume  fraction  had  minimal  impact  on  the
          RCFs (RSD<3%,  n=3).  Comparison  with  the  external  standard  method  showed  no  significant  differences  in  the  content  of  each
                                                             component  across  batches,  except  for  caffeic  acid  in  the  ZS12
