This article presents the results of a study of the amino acid composition of the roots of Ferula lipskyi, a plant native to the Fergana Valley. Plants of the genus Ferula are a valuable source of natural biologically active substances and are widely used in folk and traditional medicine due to the presence of essential oils, resins, coumarins, flavonoids, terpenoids, amino acids, and mineral compounds. The aim of the study was to qualitatively and quantitatively determine the amino acid composition of Ferula lipskyi roots. The analysis was performed by high-performance liquid chromatography with a fluorescence detector on an Agilent 1260 II Infinity system using standard amino acid samples. Serine, glycine, threonine, arginine, alanine, lysine, valine, methionine, phenylalanine, isoleucine, and proline were identified in the sample. The highest content was found for threonine—0.98 mg/g, glycine—0.79 mg/g, and lysine—0.53 mg/g. Asparagine, glutamine, histidine, glutamate, and tryptophan were not detected in the test sample. The obtained data demonstrate the specificity of the amino acid profile of Ferula lipskyi and confirm the promise of further phytochemical and pharmacological study of this plant as a potential source of natural biologically active compounds for the pharmaceutical and food industries.
