ABSTRACT
Objective:
An UPLC-LTQ-Orbitrap-MS spectrometry method has been developed for the efficient separation and detection of C-glycosyl flavonoids in the extract of Scutellaria baicalensis differentiation of isomers.Methods:
Data were acquired by Orbitrap. MS2, MS3, and MS4 data were triggered by data-dependent acquisition mode. Isomers of C-glycosyl flavonoids were distinguished by a comparison study of mass distribution.Results:
A total of 19 compounds were identified as C-glycosyl flavonoids, and several isomers were successfully discriminated.Conclusion:
This method is proved to be powerful for the identification of C-glycosyl flavonoids and provides the important complementary information for other flavonoid analysis.
