The relevance of this study is due to the insufficient knowledge of the biological characteristics of hydrangeas. The aim of this research was to identify the anatomical and diagnostic features, as well as the chemical composition, of the arborescent hydrangea (Hydrangea arborescens L.) from the collection of the Southern Ural Botanical Garden-Institute, Ural Federal Research Center, Russian Academy of Sciences. As a result of this research, it was found that the diagnostically significant features of the leaf of this type of hydrangea are the structure of the cells of the epidermis of the upper and lower sides of the leaf, the presence of an anomocytic stomatal apparatus on the lower side of the leaf, crystalline inclusions of calcium oxalate in the form of raphides on the upper and lower sides of the leaf, and simple hairs with a coarse warty surface, multicellular base, and simple sinuous hairs on the underside of the leaf. Phytochemical analysis of the leaves, stems, and roots confirmed the presence of coumarins, ascorbic acid, and tannins in them, as well as of flavonoids in leaves. It has been established that the highest content of ascorbic acid (0.28 ± 0.014%) and tannins (7.13 ± 0.639%) is observed in the leaves of Hydrangea arborescens; coumarins in terms of umbelliferone are in the roots (0.41 ± 0.007%); and the content of flavonoids in the leaves was 1.14 ± 0.048%. © 2023, Pleiades Publishing, Inc.
