Introduction. Synthetic medicinal products play a significant role in modern medicine; however, herbal preparations are also widely used due to their good tolerability and low incidence of side effects. In recent years, particular attention has been paid to plant polysaccharides as promising biologically active compounds with diverse pharmacological properties. Therefore, the search for new medicinal plants containing primary metabolites remains a relevant task. The Aim of the Study. To determine the qualitative composition and quantitative content of carbohydrates in the herb of garden tradescantia and Chinese miscanthus. Materials and Methods. The study material consisted of dried and powdered herb of garden tradescantia and Chinese miscanthus, cultivated and harvested in July–August 2025 in the Ternopil region. The qualitative composition and quantitative content of carbohydrates were analyzed by GC/MS. Results and Discussion. Free carbohydrates in Chinese miscanthus herb included D-glucose, D-galactose, inositol, D-fructose, and D-sucrose, whereas garden tradescantia herb contained D-glucose, inositol, and D-fructose. D-sucrose predominated in Chinese miscanthus (11.54 mg/g), while D-glucose was the dominant free sugar in garden tradescantia (2.75 mg/g). After hydrolysis, D-xylose (56.78 mg/g) and D-glucose (27.57 mg/g) were the major monosaccharides in Chinese miscanthus. In garden tradescantia, their contents were 27.26 mg/g and 40.64 mg/g, respectively. Conclusions. The carbohydrate composition of garden tradescantia and Chinese miscanthus herb was investigated using GC/MS. It was established that D-sucrose predominates among free sugars and D-xylose after hydrolysis in Chinese miscanthus. In garden tradescantia, D-glucose was the dominant compound both among free monosaccharides and after hydrolysis. The obtained results indicate that both plants may be considered promising sources of biologically active compounds of primary metabolism.
