The species 
C. junceum
L. is distributed in deserts and sandy steppes of North 
Africa, Western Siberia, Anterior and Central Asia. Tannins, phenol-carboxylic acids, 
alkaloids, leucoanthocyanidins, flavonoids were found in the chemical composition of 
the plant. The alkaloid kalligonin with hypotensive activity has been isolated from the 
herb 
C. junceum
, phenolic carboxylic acids of the plant have a choleretic effect, 
leucoanthocyanidins and a number of flavonoids exhibit antitumor activity.
For the first time, we studied the lipids of air-dry leaves of 
C. junceum
collected in 
2021 on the drained bottom of the Aral Sea. The yield of total lipids (TL) was 1.86% (of 
leaf weight). TL was divided by the CC method on silicagel into neutral lipids (NL, 
0.34%), glycolipids (GL, 1.27%) and phospholipids (PhL, 0.25%). According to TLC 
data, sterylglycosides and esters of sterylglycosides predominated in GL, they were 
accompanied by cerebrosides, di- and monohalactosyldiglycerides, chlorophyll 
derivatives. Squalene, carotenoids, fatty acid esters (FA) with triterpenols and 
phytosterols, cyclic alcohol acetates, triacylglycerides, free FA, triterpenols and 
phytosterols were found in the NL. phosphatidylethanolamines, phosphatidylcholines 
(the main component), phosphatidic acid and phosphtidylinosites were found in the 
composition of PhL. The composition of FA lipids was determined by GC on an Agilent 
GC 8860 chromatograph. (table).

The results show that saturated fatty acids predominate in all lipid groups (mainly 
16:0), the amount of unsaturated FA ranges from 22.6 to 33.44%, with most of the 
amount being 18:1 acid.
