a the analytes are listed in the order of their elution; b the m/z values were derived from the acquired spectra; c the m/z values were calculated based on the predicted elemental composition (EC); d the elemental compositions were predicted with mass tolerance of 10 ppm; e MS/MS fragmentation patterns are provided as m/z values of the fragment ions (their relative intensities); f literature references providing information on the elemental compositions and MS/MS fragmentation patterns of the annotated compounds; EA- compounds were found in the ethyl acetate extract of water avens; A—compounds were found in the aqueous extract of water avens; HHDP—hexahydroxydiphenoyl group.
