ABSTRACT
The qualitative analysis of flavonoids in Coreopsis tinctoria was carried out by a combination of 2 D-TLC and HPLC-IT-TOF-MS. The separation was conducted on 2 D-TLC and a Phenomenex Kinetex Evo C_(18) column(2.1 mm×100 mm, 2.6 μm) with methanol-0.05% aqueous formic acid by gradient elution. Electrospray ionization-(ESI) source was applied and operated in both positive and negative ionization modes. Eighteen flavonoids including three flavonoids, one flavonol, nine flavonones, one flavanonol and four chalcones, were putatively identified from the flavone-enriched fraction of C. tinctoria. 2 D-TLC could separate the flavonoids from C. tinctoria. HPLC-IT-TOF-MS was able to quickly and accurately analyze the flavonoids in C. tinctoria. The results would provide experimental information for the efficacy material basis clarification of C. tinctoria.
