          摘   要  目的  建立并应用同时测定不同基原藏黄堇中荷包牡丹碱、原阿片碱、黄连碱含量的方法,为该类药材的基原确定和质量
          控制提供参考依据。方法  采用超高效液相色谱-三重四极杆质谱联用(UPLC-MS/MS)法:色谱柱为Agilent EC-C18 (100 mm×2.1
          mm,2.7 μm),以乙腈-0.1% 甲酸水溶液为流动相梯度洗脱,流速为 0.2 mL/min,柱温为 35 ℃。采用电喷雾离子源正离子模式检
          测,多反应监测扫描。结果  荷包牡丹碱、原阿片碱、黄连碱的进样质量浓度分别在5.88~117.60、53.70~1 074.00、4.85~97.00 ng/
          mL之间与各自峰面积成良好的线性关系(r分别为0.998 2、0.991 9、0.999 6);定量限分别为2.35、1.07、1.46 ng/mL,检测限分别为
          1.17、0.54、0.49 ng/mL;精密度、稳定性(24 h)、重复性试验的 RSD 均未超过 2.0%;平均加样回收率分别为 97.41%、98.89%、
          105.44%(RSD均小于5.0%,n=6)。结论  所建立的方法选择性好、准确度高,适用紫堇属植物中荷包牡丹碱、原阿片碱和黄连碱
          的快速分析。3种生物碱总量在不同基原药材中的含量从高到低依次为金球黄堇、尖突黄堇、矮黄堇、尼泊尔黄堇和斑花黄堇,其
          中金球黄堇和尖突黄堇中的生物碱含量比较接近,但斑花黄堇和尼泊尔黄堇中未检测到荷包牡丹碱。

          ABSTRACT    OBJECTIVE  To  establish  and  apply  a  method  for  simultaneous  determination  of  the  contents  of  dicentrine,
          protopine  and  coptisine  in  Tibetan  Corydalis  pallida  of  different  origins,  and  to  provide  reference  for  origin  determination  and
          quality  control  of  the  kind  of  medicinal  materials.  METHODS  Ultra  performance  liquid  chromatography-tandem  quadrupole  mass
          spectrometry  method  was  used.  The  determination  was  performed  on  Agilent  EC-C18  column (100  mm×2.1  mm,  2.7  μm)  with
          mobile  phase  consisted  of  acetonitrile-0.1%  formic  acid  by  gradient  elution.  The  flow  rate  was  0.2  mL/min,  and  the  column
          temperature  was  set  at  35  ℃ .  MS  detection  was  carried  out  by  electrospray  ionization  in  positive  modes,  multiple  reaction
          monitoring  mode  was  used  for  quantitative  analysis.  RESULTS  The  injection  mass  concentrations  of  dicentrine,  protopine,
          coptisine  ranged  from  5.88  to  117.60,  53.70  to  1  074.00,  and  4.85  to  97.00  ng/mL,  respectively,  showing  a  good  linear
          relationship  with  their  respective  peak  areas (r=0.998  2,  0.991  9,  and  0.999  6,  respectively).  The  limits  of  quantitation  were
          2.35, 1.07 and 1.46 ng/mL; the limits of detection were 1.17, 0.54, 0.49 ng/mL, respectively. RSDs of precision, stability (24 h)
          and repeatability tests were all lower than 2.0%. The average recovery rates were 97.41%, 98.89% and 105.44% (all RSDs<5.0%,
          n=6).  CONCLUSIONS  The  established  method  has  good  selectivity  and  high  accuracy,  and  is  suitable  for  the  rapid  analysis  of
          dicentrine,  protopine  and  coptisine  in  Corydalis.  The  total  contents  of  three  alkaloids  in  different  original  medicinal  materials  are
          from high to low in order of C. chrysosphaera, C. mucronifera, C. pygmaea, C. hendersonii and C. conspersa. The alkaloid contents
          in C. chrysosphaera and C. mucronifera are relatively similar, but no dicentrine has been detected in C. conspersa and C. hendersonii.
