The composition and content of phenolic compounds in plants of the polymorphic species Bassia prostrata (Chenopodiaceae) from geographically distant populations were studied by high-performance liquid chromatography. The material for the study was the aboveground part of the plant. The plants were collected in the flowering phase in Russia (Novosibirsk region, Republic of Tyva, Khakassia, Buryatia, Altai), Kazakhstan, Armenia. The phenolic compounds were extracted by double extraction with 70% ethanol. Component composition of the phenolic complex was investigated by Agilent 1200 chromatograph. Eleven phenolic compounds, including isoquercitrin, kaempferol-3-glycoside, isoramnetin-3-rutinoside, and luteolin were found in the composition. The quantitative content of each compound could vary from 0.1 to 10.8 mg/g in different populations. Chemotypes were determined for the qualitative and quantitative content of phenolic compounds
The study of species of the genus Salsola L. in the desert part of the Syrdarya river valley (Kyzylorda region) is of great importance for identifying the features of the structure of phytocenoses in this region, which will facilitate rational use of plant resources and make recommendations for the radical improvement and recultivation of pastures in this territory. Various phytocenoses are confined to this territory, including those with the participation (dominance) of species of the genus Salsola L. Classical botanical methods were used in the research process. Fundamental floral summaries were used to identify the collected material. Vegetation was studied applying traditional methods of field geobotanical research. According to the results of the expedition work in the desert part of the Syrdarya river valley, 24 plant communities were described with the participation and dominance of species of the genus Salsola L. The communities differed from each other in the composition of the species. This is due to the diversity of the combination of environmental factors: natural physical and geographical and anthropogenic. The 24 communities represented can be divided into two groups: 1) communities dominated by species of the genus Salsola; 2) communities containing species of the genus Salsola. As a result, it was found that the annual species of the genus Salsola: S. nitraria, S. paulsenii and S. tragus are well adapted to the habitat conditions in the study area and can be used in reclamation work in desert zones.
