Salt-resistant plant 
Salsola pestifer
A. Nelson fam. 
Amaranthaceae
is distributed in 
Tashkent, Fergana, Samarkand, Bukhara regions of Uzbekistan and in Karakalpakstan. 
It is a source of artisanal extraction of potash for making soap. The ash of the plant is 
used for handicraft dyeing of wool. Tetrahydroisoquinoline alkaloids with 
anticholinesterase and antioxidant activity have been isolated from the herb. The 
composition of phenolic compounds, amino acids was studied, acute toxicity and 
hepatoprotective effect of the 
S. pestifer
herb extract were established. We studied the 
lipids of mature seeds of 
S. pestifer
with an admixture of the aerial part, collected on 
saline lands of the Jizzakh region in 2022. It was found that the moisture content of raw 
materials is 4.9%, the content of neutral lipids (NL) is 5.22%, and polar lipids (glyco- 
and phospholipids) are 0.78%. In NL, triacylglycerides (the main class), hydrocarbons, 
esters of fatty acids (FA) with aliphatic alcohols, triterpenols and sterols, as well as free 
FAs, triterpenols and sterols were found. FAs were isolated from NL by alkaline 
hydrolysis by treatment with diazomethane, they were converted into methyl esters, 
which were analyzed by GC on an Agilent GG 8860 chromatograph. The results are 
shown in the table.

The results show that the seeds of 
S. pestifer
contain an insignificant amount of lipids 
with a complex composition of fatty acids (20 components), which have a high total 
unsaturation (90.38%) and an approximately equal ratio of the dominant oleic 18:1n9 
and linoleic 18:2n6 acids (1:1). The FA contains gamma-linolenic (γ-18:3n6, 4.59%), 
eicosatrienoic (20:3n3) and arachidonic (20:4n6) with high biological activity.
