Abstract: The fruits of four Sorbus subgenera ( Sorbus x arnoldiana ‘Copper Glow’, Sorbus ‘White Swan’, Sorbus intermedia and Sorbus ‘Alaja Krupnaja’) were identified and subjected to quantitative analysis of polyphenolic compounds using LC-ESI-QTOF-MS/MS and UPLC-PDA. In the studied Sorbus subgenera, 101 polyphenolic compounds were identified classified into four groups: flavan-3-ols (2), phenolic acids (21), flavonols (66) and anthocyanins (12). Of the 101 compounds identified, 59 were reported for the first time in Sorbus fruit. Flavonols (66 %), derivatives of quercetin and kaempferol, including diglycosides (55 %), monoglycosides (31 %), triglycosides (14 %), and acylated forms (27 %) were dominant in the tested fruits. The polyphenol content was highest in Sorbus x arnoldiana ‘Copper Glow’ (531.25 mg/g), followed by Sorbus ‘White Swan’ (210.67 mg/g), Sorbus intermedia (131.07 mg/g), and Sorbus ‘Alaja Krupnaja’ (81.43 mg/g). Sorbus x arnoldiana ‘Copper Glow’, with its characteristic orange fruit colour, was notable for its rich qualitative profile, in particular flavonols, and contained the highest levels of these compounds among the tested subgenera. • Sorbus subgenera subjected to polyphenols LC QTOF/ESI-MS and UPLC-PDA analysis • 101 polyphenols: flavan-3-ols (2), phenolic acids (21), flavonols (66) and anthocyanins (12) • Flavonols (66 %), derivatives of quercetin and kaempferol were dominant in Sorbus • 59 compounds were identified in the tested Sorbus fruit species for the first time
