Abstract

 This article for the first time presents the results of the study of qualitative and quantitative elemental and amino acid composition of the aboveground part of the plant Nepeta olgae Regel (L.) taken in the territory of Chust and Kosonsai districts (from the slopes of Gova and Kosonsai mountains) of Namangan region during the period before and during flowering (May-June, 2021-2022).
 The use of instrumental analysis of high-throughput energy dispersive X-ray fluorescence spectrometry, allowed to establish 20 mineral elements in the plant Nepeta olgae Regel (L.), among which to vital 9 elements and 3 to conditionally necessary.
 The amino acid composition of the plant Nepeta olgae Regel (L.) was studied by high performance liquid chromatography (HPLC) and 17 compounds were identified. Of these, 8 were substitutable and 9 essential amino acids.
