were isolated from the ethylacetate fraction of plant. Investigation of 
their spectral data (UV, IR and NMR spectroscopy) and comparison them with the 
literature as well as direct comparison with authentic samples the structures of the 
isolated compounds were established as: 
salicylic acid (1), 
caffeic acid (

3-O-methylquercetin (

and 
patuletin (5). 
All isolated secondary metabolites were isolated first time from the 
A. porrecta.

Delphinium semibarbatum
Bien. ex Boiss. - perennial herbaceous plant of the 
Ranunculaceae family, growing on the loess slopes of the foothills in the middle belt of 
mountains in the Tashkent, Namangan, Andijan, Fergana, Samarkand, Kashkadarya, 
Bukhara and Surkhandarya regions. 
The purpose of our research was to study the chemical composition of flowers of 
D. 
semibarbatum
, collected during the flowering period in the mountainous areas of the 
Akhangaran district of the Tashkent region. 
We have studied the component compositions of the ethyl acetate and n-butanol 
fractions of the alcoholic extract of 
D. semibarbatum
flowers. The ethyl acetate fraction 
was separated on a column with KSK silica gel, eluting with chloroform and a gradient 
mixture of chloroform-methanol with increasing methanol content. Eight individual 
compounds were isolated by subsequent rechromatography of the obtained subfractions 
on Sephadex LH-20 and elution with an ethanol-water mixture (8:2): 
D
-mannitol (1), 
undulatoside A (
