Simultaneous Determination of Pyrrolidine Alkaloids and Their Nitrogen Oxides in Farfarae Flos by UPLC-MS/MS
To establish an ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) for the simultaneous determination of 15 pyrrolidine alkaloids (PAs) and their nitrogen oxides
and determine the content of the 15 PAs in the 15 batches of Farfarae Flos samples obtained from different sources
in order to understand the distribution status of these 15 PAs in Farfarae Flos from different sources
and provide relevant references for the safe and rational use of this medicinal materials.
Method:
2
The method was achieved by Agilent Eclipse Plus C
18
column (3.0 mm×150 mm
1.8 μm) using a mobile phase made up of 0.05%formic acid and 2.5 mmol·L
-1
ammonium formate in water (A)-0.05%formic acid and 2.5 mmol·L
-1
ammonium formate in methanol(B). The flow rate and the injection volume were 0.4 mL·min
-1
and 2 μL
respectively. The column temperature was 40 ℃. The instrument was Agilent 1290-6470 QQQ ultra high performance liquid chromatography-triple quaternary bar mass spectrometer. The components were detected in multiple reaction monitoring mode by mass spectrometry with ionizationmode of ESI
+
. The content of the components measured in the samples was calculated by using the external standard method
and the difference between samples was analyzed based on RSD of different components.
Result:
2
The established method had a high sensitivity and good separation degree. The results of methodological investigation met the requirements. The results showed that all of the 15 batches of Farfarae Flos contained PAs and their nitrogen oxides. These PAs had almost the same types of structure. There were significant differences in the content and distribution of PAs in Farfarae Flos obtained from different sources.
Conclusion:
2
In general
Farfarae Flos contains pyrrolidine alkaloids and their nitrogen oxides. Senkirkine with a significant hepatotoxicity is the main compound. The content determination of PAs will provide scientific fundaments for the safe and effective use of Farfarae Flos.
