Abstract
At present, there is no modern annotated checklist of rare medicinal plant species of the North Kazakhstan Region (NKR). This study presents extended data profiles of these representatives of the flora, compiled based on the analysis of scientific publications, field research materials, and herbarium collections of university researchers. According to the compiled list, eleven species of rare medicinal plants of the North Kazakhstan Region are identified. Among them, four species belong to the family Ranunculaceae, while one species each belongs to the families Poaceae, Liliaceae, Lythraceae, Droseraceae, and Menyanthaceae; two species belong to the family Orchidaceae. The taxonomic position, morphology, and ecological characteristics of each species are examined. Particular emphasis is placed on their pharmacological properties, confirming their value as sources of biologically active compounds. Special attention is given to the rarity status of the plants and their distribution within the North Kazakhstan Region, reflecting the uniqueness of the forest-steppe and steppe ecosystems of the region. The results of the study highlight the importance of such research as a tool for inventory and legal regulation of plant protection, as well as the need for further investigation of the pharmacological potential of rare species.
