Abstract
Morphological and anatomical study of medicinal plant raw materials plays an important role in the development of new drugs based on local natural raw materials. This work presents the results of macroscopic and microscopic analysis of the aerial and underground organs of the plant Patrinia intermedia (Hornem.) Roem. et Schult. from the Valerianaceae family, growing in Central Kazakhstan. The plant was collected during the mass flowering period in August 2024 in the Karaganda region, in the vicinity of the village of Karkaralinsk. Patrinia intermedia (Hornem.) Roem. et Schult. is characterized by a rich chemical composition, including essential oils, triterpene saponins, flavonoids, phenolic compounds, alkaloids, vitamins, polysaccharides, which determines its pronounced pharmacological effect. During the study, the following macroscopic features were studied: leaf shape, structure and color of stems, structure and appearance of flowers and roots. Microscopic examination allowed to describe in detail the anatomical features of plant tissues, to identify features inherent to the leaf, stem and root. The obtained results can be used for identification and standardization of plant raw materials of Patrinia intermedia (Hornem.) Roem. et Schult. in pharmaceutical practice. The results can also serve as a basis for the development of regulatory documents and quality standards in the production of drugs, which significantly expands the possibilities of using this plant in medical practice.
