Alhagi persarum
Boiss. &Buhse (Persian camel's thorn, Fabaceae) is a perennial 
herbaceous semi-shrub widespread in the south of European Russia, Western Siberia 
and Central Asia. In Uzbekistan it occurs in saline wet areas of Kyzylkum, Nizhne-
Zarafshan and Karshi-Karnabchul districts. 
The plant is widely used in Iraq and Afghanistan as a food and medicinal plant. In 
folk medicine, the aerial part of A. persarum, and less often fruits and roots, is used as a 
diuretic and diaphoretic. Infusions, decoctions or fresh juice are used for gastrointestinal 
diseases. Extracts from the aerial part of 
A. persarum
have antimicrobial properties.
We first studied the lipids of mature seeds of 
A. persarum
collected in the saline 
lands of Jizzakh region in 2022. Neutral lipids (NL) from the crushed seeds of 
A. 
persarum
were extracted in the Soxhlet apparatus in benzene (b.p. 72-800C) with the 
yield of 5.27%. Polar lipids (PL) were isolated from the meal by triple extraction with a 
mixture of chloroform and methanol (2:1, v/v) - 0,75%. Hydrocarbons, carotenoids, 
triacylglycerides (basic) esters of LC with aliphatic and cyclic alcohols, free fatty acids, 
triterpenols, and phytosterols were found in NL. 
Lipophilic substances (4.0%) and fatty acids were isolated from NL by alkaline 
hydrolysis. According to TLC on Silufol in the solvent system hexane: ether 4:1, the 
main component of lipophilic substances were phytosterols. Fatty acids were converted 
to methyl esters by diazomethane treatment, which were analyzed by GC on an Agilent 
GG 8860 chromatograph. The results of the FAME analysis are given in the table.

It was found that the lipids contain 16 fatty acids from 12:0 to 26:0, in the sum of the 
unsaturated acid 18:2n6 (or ω6, 68.57%) prevails. Thus, 
A. persarum
seeds are a 
promising source of biologically active linoleic acid.
