Сomposition and content of phenolic compounds in the leaves and flowers of three varieties of Pentaphylloides fruticosa were studied. Each of the variety was found to have its own phenolic profile. Main glycosides of flavonol types identified were as follows. Quercetin glycosides were characteristic for the varieties of P. fruticosa “Kobold” and “Tangerine”. The variety of P. fruticosa “White moon” with white flowers was characterized by kaempferol glycosides in flowers and rhamnetin glycosides in leaves. Specificity of the varieties was found regarding to the contents of quercitrin, astragalin, quercetin and rhamnetin.Key words: Rosaceae, Pentaphylloides fruticosa, variety, phenolic compounds, Amur Region.
