ANALYSIS OF THE CHEMICAL COMPOUNDS OF THE PLANT LAGOTIS KOROLKOWII (PLANTAGINACEAE)
Abstract
This study is the first to analyze the flavonoids, amino acids, and vitamins present in the Lagotis korolkowii plant distributed in the territory of Uzbekistan. Twenty amino acids were identified in the samples, of which eight were non-essential, eight were essential, and four were conditionally essential. The total amino acid content of the roots was 9.35 mg/g, whereas that of the aerial parts was 68.35 mg/g. According to the comparative analysis, the aerial parts of Lagotis korolkowii were quantitatively richer in amino acids than the roots. Flavonoids in various parts of Lagotis korolkowii were analyzed for the first time. The results showed that the aerial parts of the plant contained kaempferol, rutin, hypolaetin, hyperoside, and apigenin. Additionally, it was found for the first time that Lagotis korolkowii contains large amounts of vitamins B and C and PP. The obtained data allowed us to consider Lagotis korolkowii as a source of flavonoids, valuable amino acids with a wide spectrum of pharmacological activity, and rich in vitamins, which can be used for the development of new food supplements and pharmaceutical substances.
