Abstract
Flavonoids are important and even the most active principles of plants and herbal preparations used in folk and scientific medicine as bile, anti-inflammatory, antispasmodic, antiallergic and vasodilating agents. The article is devoted to the study of flavonoids of the aboveground part of Russowia sogdiana (Bunge) B. Fedtsch. family Asteraceae. Russowia sogdiana is an annual herbaceous plant, found on the outcrops of variegated rocks in the lower belt of the Central Asian mountains. From the ethyl acetate fraction of the ethanol extract of the aerial part of the aboveground part of the plant, seven individual flavonoids were first isolated by column chromatography on silica gel and Sephadex LH-20. Based on the results of acid hydrolysis and oxidation with a solution of iron (III) chloride, IR, UV, 1H, and 13C NMR data and mass spectra and a comparison of physicochemical constants with literature data, the compounds obtained were identified with known flavonoids apigenin, quercetin, isorhamnin, quercetin-7-O-β-D-glucopyranoside, isorhamnetin-7-О-β-D-glucopyranoside, saponaretin and vitexin.
