This study is devoted to investigating the biochemical composition, nutritional value, and pharmaceutical potential of Stevia (Stevia rebaudiana Bertoni). During the research, the steviol glycosides, phenolic compounds, and amino acid complexes of the plant leaves were analyzed using modern analytical methods.
The results revealed that stevia raw material is dominated by stevioside (60-70%), rebaudioside A (20-30%), and flavonoids, which determine its high therapeutic efficacy as a natural non-caloric sweetener. Additionally, a total of 10.48% amino acids were identified in the leaf composition, with 4.65% consisting of essential types. The study demonstrates the hypoglycemic, hypotensive, antimicrobial, and antioxidant properties of stevia extract, as well as its potential to regulate metabolic processes and support weight management.
The obtained data indicate that the cultivation of Stevia rebaudiana Bertoni under the Republic's climatic conditions is of great importance in creating a strategic raw material base for the pharmaceutical, dietetic, and food industries as an import-substituting product.
