Plants of the genus 
Astragalus
are sources of flavonoids, alkaloids, saponins, 
coumarins, and triterpenoids with antioxidant activity, which significantly increases the 
value of medicinal raw materials [1]. 
It is known that macro-microelements are concentrated in astragalus, each of which, 
in turn, affects the synthesis of biologically active compounds with various 
physiological activities [2]. 
One of the main directions of expanding the resource base of useful plants and 
identifying new opportunities for their use is the cultivation of plants. 
The research aimed to study the composition of the elemental composition in the 
aerial and root parts of the plant 
Astragalus xanthomeloides
. 
A. xanthomeloides
seeds were sown on February 25, 2022. Plant seeds were satisfied 
with concentrated sulfuric acid for 10 minutes, after which they were planted in open 
ground at the vegetation site of the Institute of Chemistry of Plant Substances of the 
Academy of Sciences of the Republic of Uzbekistan. 
For the first time in 
A. xanthomeloides 
plants grown in the conditions of the city of 
Tashkent, 44 elements were identified, of which the predominant macro-K, Ca, Mg, Na, 
P, and microelements - Al, Si, and Fe. Toxic elements, Cd, Hg, Bi, and Sb, were not 
found in the aerial part and the roots of 
A. xanthomeloides
. 
According to the results of the analysis, it was revealed that in the vegetative shoots 
of 
A. xanthomeloides
, the content of macro elements was: K - 26390.77; Ca, - 10936.63; 
Mg - 1627.886; P - 23.978 and was more than in the roots, in which this indicator was: 
K - 563.776; Ca - 1590.387; Mg - 563.776; P - 19.227.62 mg/kg. The quantitative 
content of Na was found to be higher in the roots of the plant - 1580.917 mg/kg than in 
the aerial part. -342.392 mg/kg. 
The content of Se in the above-ground part of the plant was 0.272 mg/kg, and in the 
roots - 0.022 mg/kg.
