The plant 
Halimodendron halodendron
(Pall.) Voss, silver chingil is the only 
representative of the genus 
Halimodendron
of family Fabacea (Leguminosae). 
H. halodendron
grows in saline soil, is photophilous, drought-resistant has a 
powerful and branched root system, and gives abundant root shoots. 
H. halodendron
is used as an ornamental plant for landscaping, thorn hedges, and 
protective afforestation. A yellow dye is obtained from the roots for wool. these are 
used only in late autumn as feed for livestock. 
The purpose of this work is to study the chemical constituents of the essential oil and 
carbohydrates from the aerial part of 
H. halodendron
. The raw material was harvested 
in 2022 in the flowering phase in the Taslak village of the Republic of Karakalpakstan. 
By hydro distillation of a fresh sample of the aerial parts of the plant (leaves and 
flowers), the essential oil was obtained and compounds have been identified that make 
up 89.69% of the volatile components. 
The essential oil contains the following major compounds: 
cis
-3-hexene-1-ol 
(2.44%), 1-octen-3-ol (3.20%), benzenemethanol, α,α-dimethyl-(1.22% ), 
l
-cysteine, 
S
-
propyl- (2.42%), methyl-d3 2-methyl-2-propenyl ether (24.14%), ethanethioic acid 
(20.47%), maltol (4.35%), 2-methoxy-4-vinylphenol (5.28%), benzofuran, 2,3-dihydro- 
(3.93%), indole (1.23%), palmitic acid (1.39%). 
Thus, the qualitative and quantitative constituents of compounds of essential oil from 
the aerial part of the 
H. halodendron
plant growing in the Republic of Karakalpakstan 
was revealed. The carbohydrate composition of the plant was studied, and 
polysaccharides (7.7%), pectin substances (2.1%), and hemicellulose (10.2%) were 
isolated and characterized, the monosaccharide of which is represented by acidic and 
neutral monomers.
