The aim of our study was to explore variation peculiarities of qualitative and quantitative composition of phenolic compounds in leaf samples of rowan (Sorbus aucuparia L.) plants growing in natural habitats of Lithuania during their growth season using the HPLC method. In rowan leaf samples, collected during different phenological stages, qualitative and quantitative estimation of neochlorogenic acid, chlorogenic acid, caffeic acid, hyperoside, isoquercitrin, rutin, astragalin, (−)-epicatechin, procyanidin B1 and procyanidin B2 was performed. Analysis of the qualitative and quantitative composition of phenolic compounds in ethanol extracts of leaf samples of S. aucuparia growing in natural habitats of Lithuania revealed a close relationship between the content of phenolic compounds in S. aucuparia raw plant material and different growth stages.
