Analysis and Identification of Chemical Constituents of Citri Sarcodactylis Fructus by UPLC-Q-Orbitrap HRMS
To analyze and identify the chemical constituents of Citri Sarcodactylis Fructus by an ultra-high performance liquid chromatography coupled with hybrid quadrupole-orbitrap high-resolution mass spectrometry (UPLC-Q-Orbirap HRMS) method.
Method:
2
Compounds were separated on Thermo Scientific Accucore™ C
18
column (3 mm×100 mm
2.6 μm). The mobile phase was 0.1% formic acid solution and 0.1% formic acetonitrile solution. The flow rate was 0.3 mL·min
-1
and the column temperature was set at 30 ℃. HRMS was performed using an electrospray ion source (ESI)
and scanned in a positive ion mode by means of full scan/data dependent secondary scan (Full MS/dd-MS
2
). Compound Discoverer 3.0 software that could be linked to mzCloud network database and local high-resolution mass spectrometry database of traditional Chinese medicine components was used to analyze the data
based on accurate molecular mass
retention behaviors and characteristic ion fragmentation of the compounds
as well as literature information and relevant reference materials.
Result:
2
Totally 54 chemical constituents in Citri Sarcodactylis Fructus were identified
including 16 flavonoids
17 coumarins
3 limonoids
6 nucleosides and nucleobases
2 organic acids
3 aromatic aldehydes
1 amino acid and 6 other components.
Conclusion:
2
The established UPLC-Q-Orbitrap HRMS method can be used to effectively and rapidly identify main chemical constituents of Citri Sarcodactylis Fructus. The findings provide a methodological reference and theoretical foundation for defining the pharmacodynamic material base and optimizing quality control index of Citri Sarcodactylis Fructus
which is of guiding significance for further development and utilization of the resources.
