Morphological and anatomical structure of Rubus saxatilis leaf

Abstract

Introduction to the practical use of local raw materials of medicinal plants has an important practical significance
for pharmacy and cosmetic industry. Interest in raw materials of Rubus saxatilis is due to the biological
activity of compounds, use in folk medicine, as well as significant amounts of raw materials growing in
Central Kazakhstan. To introduce the raw material into practical application, the task of analyzing the
anatomo-morphological structure and identifying diagnostic features of the raw material was set. The results
showed that at the macroscopic level as diagnostic features of Rubus saxatilis raw material can be indicated
the difference in the structure of the upper and lower side of leaves, type of veining, the presence of soft
prickles, the structure of triple-complex leaves, almost complete absence of pubescence. At the microscopic
level, the diagnostic features of this species are the shape of transverse sections, the shape of leaf epidermis
cells and leaf petiole, the localization of receptacles in the mesophyll, the presence of rare simple unicellular
trichomes and essential oil glands raised above the surface of the epidermis. The results obtained can serve as
additional taxonomic characters in determining the species and authentication of raw materials of Rubus
saxatilis.
