Abstract
The research work is devoted to the study of the biodiversity of medicinal plants in the Kyzylzhar district of the North Kazakhstan region. Compiled a list of medicinal species and taxonomic composition distribution. Based on our research, 162 species from 131 genera and 40 families were identified. A large family containing 12 species (18.75%) of medicinal plants used in official medicine is Rosaceae. In second place is the aster family (Asteraceae), which includes 10 plants from 9 genera. The legume family (Fabaceae) contains 8 plants from 4 genera, the buckwheat family (Polygonaceae) includes 6 medicinal plants from 3 genera. Of these, 22 families are represented by only one species and one genus, for example, these are such families as: Iridaceae, Asparagaceae, Utricaceae, Lamiaceae and others. A large family containing 12 species (12.24%) of medicinal plants used in traditional medicine is the Asteraceae family. 7 species of medicinal plants contain families: ranunculaceae (Ranunculaceae), legumes (Fabaceae), umbellate (Apiaceae). The family Rosaceae (Rosaceae) consists of 6 species of medicinal plants. The Rosaceae family, which is a large family in terms of the number of species of medicinal plants used by official medicine, is considered in more detail. The useful properties of some medicinal plants belonging to traditional and alternative medicine are described.
