Microdiagnostic characteristics of the herb Artemisia austriaca Jacq. (Artemisia austriaca Jacq.)

Introduction. Artemisia austriaca Jacq. is a perennial herbaceous plant of the Asteraceae family, popular in folk medicine due to its various biological activities, in particular: wound-healing, anticonvulsant, analgesic, antipyretic and others. In addition, this plant is in the same section as the pharmacopoeial species – wormwood bitter. In the dynamically developing pharmaceutical field, one of the aspects of expanding the base of medicinal plants as sources of phytopreparations is the study of wild plants close to officinal species. One of the initial stages on the way to the development of regulatory documentation for medicinal plant raw materials is the identification of their authenticity criteria that allow reliable identification. Objective: Study of anatomical-diagnostic features of Artemisia austriaca Jacq. of the Saratov region. Material and methods. The objects of the study were samples of Artemisia austriaca Jacq. herbs harvested in 2021 in the Saratov region. The study of the structure of A. austriaca herbs was performed according to the instructions of GPA.1.5.3.0003 "Microscopic and microchemical analysis of medicinal plant raw materials and drugs of plant origin" in the 15th edition of the Russian Federation’s State Pharmacopoeia. Results. The anatomical-histological study of stem, petiole, inflorescence of Artemisia austriaca growing on the territory of Saratov region has been carried out. As a result of the work the markers, luminescent characteristics of tissues, which help to authenticate the raw materials of this taxon, were revealed and clearly presented. Conclusion. The results obtained provide the possibility to identify the mentioned raw material, as an individual, and in addition, in a complex multicomponent phytocomposition.
