| description | The paper presents the results of studying biologically active substances (BAS) in the leaves of sea buckthorn and black currant growing in the Republic of Buryatia. The analysis of the content of vitamin C, tannins, flavonoids, and the total amount of antioxidants in water-alcohol extracts obtained using ethanol of various concentrations has been carried out. It has been established that specific extraction conditions, including the optimal alcohol concentration and duration of the process, are required for the maximum extraction of individual BAS. For example, the highest content of ascorbic acid in sea buckthorn leaves is achieved using 60 % ethanol and maceration for 120 hours, while for tannins, the optimal condition is a 70 % alcohol solution with boiling for 45 minutes. In black currant leaves, the maximum concentration of vitamin C is observed after 120 hours of maceration with 50 % ethanol, and the highest yield of flavonoids has been achieved by extraction with 70 % alcohol for 60 minutes. The highest content of antioxidants in sea buckthorn leaves has been achieved using 60 % alcohol, while in black currant leaves, it has been achieved with 50 % alcohol. The content of water-soluble vitamins has also been determined in the extracts. The extract from sea buckthorn leaves contains vitamin C – 0,805 mg/g, while the extract from black currant leaves – 0,105 mg/g. Additionally, the content of B-group vitamins has been determined in the extracts from sea buckthorn and black currant leaves. The obtained data confirm the potential of using plant raw materials from Buryatia and their extracts for the development of dietary supplements, pharmaceutical preparations, and functional ingredients for the food industry. The study emphasizes the importance of optimizing technological processes to preserve the biological activity of extracts and their further application in various fields. |
