The Biological Active Substances of and from the Siberian Federal District.

Currently, scientists are increasingly focusing on utilizing the natural flora of the planet to search for and isolate individual bioactive substances that prevent various diseases, contribute to increased life expectancy, and affect all major life-supporting systems in the human body. This study describes the examination of the composition of plant raw materials from the Siberian Federal District. The research focuses on plant specimens from the root parts of and , collected in the Kemerovo region.

Evaluation of the In Vivo Anti-Atherosclerotic Activity of Quercetin Isolated from the Hairy Roots of Ledeb.

This study aimed to investigate the anti-atherosclerotic properties of quercetin isolated from the extract of Ledeb hairy roots. During the study, the hormonal composition of the nutrient medium for cultivation of hairy root biomass was selected: Gamborg's medium enriched with the cytokine 6-benzylaminopurine (1.5 mg/1 dm).

Relevance of Bioassay of Biologically Active Substances (BAS) with Geroprotective Properties in the Model of the Nematode Caenorhabditis Elegans in In Vivo Experiments.

Aging is an inevitable process of nature. The age of living organisms contributes to the appearance of chronic diseases, which not only reduce the quality of life but also significantly damage it. Modern medicines can successfully fight multiple diseases and prolong life.

Evaluation of Biocompatibility and Antagonistic Properties of Microorganisms Isolated from Natural Sources for Obtaining Biofertilizers Using Microalgae Hydrolysate.

Determination of the biocompatibility of microorganisms isolated from natural sources (Kemerovo Oblast-Kuzbass) resulted in the creation of three microbial consortia based on the isolated strains: consortium I (, , and ), consortium II (, , and ), and consortium III (, ; ; and ). The nutrient media composition for the cultivation of each of the three studied microbial consortia, providing the maximum increase in biomass, was selected: consortium I, nutrient medium 11; consortium II, nutrient medium 13; for consortium III, nutrient medium 16. Consortia I and II microorganisms were cultured at 5-25 °C, and consortium III at 50-70 °C.
