The histochemical analysis of medicinal plants and raw materials makes it possible to establish the presence of certain groups of active and related substances or products of their metabolism, as well as to study their localization in tissues. The article presents the results of histochemical analysis of leaves, flowers, petioles and stems of Filipendula vulgaris and Filipendula ulmaria. These types of plant are used in traditional medicine as an anti-inflammatory, antipyretic and bactericidal agent. Our research objective - to determine the peculiarities of the localization features of individual groups of secondary metabolites in the aerial part of meadowsweet and meadowsweet growing in the territory of Central Kazakhstan at the microscopic level. Materials and Methods. Transverse sections of petioles, stem and whole flower; transverse and superficial sections of leaves of Filipendula vulgaris and Filipendula ulmaria were fixed in Strauss-Fleming solution, after which histochemical reactions were carried out to locate and identify essential oils, phenolic acids, flavonoids, sesquiterpene lactones, polysaccharides and alkaloids. The study of microscopic signs, as well as histochemical tests were carried out according to the methods of the State Pharmacopoeia of the Republic of Kazakhstan using a light microscope Biomed-4. Results and Discussion. The localization of biologically active substances in the studied types of plant raw materials was determined by histochemical methods using light microscopy. The presence of phenolic compounds, flavonoids, traces of essential oil, alkaloids and sesquiterpene lactones was established. The absence of polysaccharides in the investigated micropreparations was established. Conclusions. For the first time, the localization of secondary metabolites in the tissues of Filipendula vulgaris and Filipendula ulmaria was studied by histochemical tests. The results of histochemical studies can be used to confirm the authenticity, identification and standardization of the aerial parts of Filipendula vulgaris and Filipendula ulmaria.
