The is concerned with the study of phenolic compound composition and its content in leaves of white poplar Populus alba L., aspen P. tremula L. and grey poplar P. × canescens (Ait.) Sm. by high-performance liquid chromatography (HPLC) method. 24 compounds of phenolic group were found, with 7 of them identified: coffee acid, quercetin glycosides – hyperoside, isoquercitrin, rutin and kaempferol glycoside – astragalin, aglycone – quercetin and galangin. The study showed that white poplar and aspen species are easily identified by HPLC by comparing the composition and content of phenolic compounds. It is found that aspen spectrum of phenolic compounds is poorer in comparison with white and grey poplar samples occupying an intermediate position between white poplar and aspen according to the composition and content of phenolic compounds, but the majority of hybrid samples deviate towards white poplar. According to cluster analysis, the studied samples are divided into 2 groups according to the compound composition and content of phenolic compounds: only 4 hybrids are related to aspen, the rest are grouped with white poplar, while the «pure» copies of white poplar do not form an independent subgroup. The relation of objects grouping with their geographical origin isn’t revealed. The obtained results indicate that in the analyzed material there are not only the F1 hybrids but also backcrosses which are closer to white poplar both according to phenolic compounds content and morphological features. These forms are most likely the result of grey and white poplars return crossings.
