Phenolic Compounds of Plants Bidens tripartita (L.) and Bidens pilosa (L.) from Different Locations

Bidens tripartita L. and Bidens pilosa L. are potential sources of biologically active substances with antimicrobial, antidiabetic, anticancer, anti-inflammatory, antioxidant, and other activities. These types of strings are widely used in different countries in phytomedicine. It was established that the studied species are rich in a variety of phenolic compounds, and plants growing in temperate continental (Tatarstan) and tropical (Burundi) climates differ slightly in the content of phenolic compounds, which indicates a genetically determined narrow amplitude of variability in the metabolism of these species. Qualitative analysis of phenolic compounds showed that the studied plant species synthesize certain groups of compounds for adaptation to specific environmental conditions. Kirimiro in the Republic of Burundi and Spassky raion in the Republic of Tatarstan can be considered as promising areas for growing and collecting the plant species under study. Temperature, altitude, rainfall, and soil composition are key factors affecting phenolic content in B. pilosa and B. tripartita plants.
