It is necessary to set up a protocol for the determination of the most abundant FOG in tea. As long as no mass spectral work is necessary and for routine work the polyamide clean-up is not essential as a separation on HPLC in combination with the detection wavelength of 354 nm is selective enough to ensure good data. The UHPLC method could serve as a basis for a relatively fast standard method for the determination of flavonol glycosides in tea.
