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 (
