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.
