Abstract
This paper presents the results of a detailed study on the anatomical structure of the leaves of the medicinal plant Arthrophytum longibracteatum Eug.Kor., which grows in the foothills of the Boguty Mountains. Arthrophytum longibracteatum is a halophytic plant and a perennial semi-shrub belonging to the family Chenopodiaceae Less. The species was first described by the Russian botanist M.E. Korovin in 1935. Arthrophytum longibracteatum plays an important role as a soil-stabilizing plant, reducing wind erosion. The study was carried out using macro- and microscopic methods, in accordance with the requirements of the Pharmacopoeia of the Republic of Kazakhstan. The assimilative tissue of the leaves is characterized by an isolateral-palisade type of structure. Palisade cells responsible for photosynthesis are arranged in a single layer. On both the upper and lower epidermis of the leaves, paracytic-type stomata were identified, ensuring gas exchange between the plant and the surrounding environment.
