To assess the potential of the raw material base of medicinal plants and search for new plant sources of biologically active substances, it is necessary to monitor and record the biological diversity of plants, their number and abundance in natural plant communities. Plants are counted by the transect method. In the course of field research in 2022, the biodiversity, abundance, and abundance of medicinal plants in three regions of Central Russia were assessed. In the Lipetsk Region (the lower reaches of the Chichera River, the valley of the Sukhaya Lubna River), the most notable species of the Ranunculaceae families were identified: Adonis vernalis L. (spring adonis); Rosaceae: Agrimonia eupatoria L. (common agrimony); Filipendula vulgaris Moench (six-petalled meadowsweet). In the Samara region (floodplain of the Sok River) - Rosaceae: Sanguisorba officinalis L. (burnet officinalis); Filipendula vulgaris Moench; Ranunculaceae: Adonis vernalis L. In the Moscow, Ryazan region (Meshchera) species of families - Rosaceae: Potentilla argentea L. (silver cinquefoil) (Rosaceae), Fragaria vesca L. (wild strawberry), Potentilla erecta L. (upright cinquefoil), Comarum palustre L. (marsh cinquefoil); Onagraceae: Chamaenerion angustifolium (L.) Scop. (fireweed narrow-leaved); Asteraceae: Helichrysum arenarium (L.) Moench.; Caprifoliaceae: Valeriana officinalis L. (valerian officinalis); Hypericaceae: Hypericum maculatum L. (St. John’s wort); Equisetaceae: Equisetum arvense L. (horsetail); Lamiaceae: Stachys palustris L. (marsh weed); Primulaceae: Lysimachia vulgaris L. (common loosestrife). A total of 65 species of medicinal plants have been identified. Species with a noticeable abundance are characterized as a source of a certain group of chemical compounds. To assess the potential of the raw material base of medicinal plants and to search for new plant sources of biologically active substances, it is necessary to monitor and account for the biological diversity of plants, their size and abundance in natural plant communities. Accounting of plants is carried out by the transect method. In the course of field research 2022 year, the biodiversity, size and abundance of medicinal plants in three regions of Central Russia were evaluated. In the Lipetsk region (the lower reaches of the Chicher River, the valley of the Sukhaya Lubna River), the most notable species were identified - Ranunculaceae: Adonis vernalis L.; Rosaceae: Agrimonia eupatoria L.; Filipendula vulgaris Moench. In the Samara region (floodplain of the Sok river) - Rosaceae: Sanguisorba officinalis L.; Filipendula vulgaris Moench; Ranunculaceae: Adonis vernalis L. In the Moscow, Ryazan regions (Meschera) - Rosaceae: Potentilla argentea L., Fragaria vesca L., Potentilla erecta L., Comarum palustre L.; Onagraceae: Chamaenerion angustifolium (L.) Scop.; Asteraceae: Helichrysum arenarium (L.) Moench.; Caprifoliaceae: Valeriana officinalis L.; Hypericaceae: Hypericum maculatum L.; Equisetaceae: Equisetum arvense L.; Lamiaceae: Stachys palustris L.; Primulaceae: Lysimachia vulgaris L. A total of 65 species of medicinal plants have been identified. Species with a noticeable number are characterized as a source of a certain group of chemical compounds.
