ФЛАВОНОИДЫ SCUTELLARIA ADENOSTEGIA BRIQ.

The article is devoted to the phytochemical study of flavonoids of roots and above-ground part of Scutellaria adenostegia Briq. families of Lamiaceae. From the overgrown part of Scutellaria adenostegia Briq. the known flavonoids norvogonin, oroxylin А, quercetin, hispidulin, and from the roots – vogonin, chrysin-7-O-methylglucuronide, oroxyloside, vogonoside, (±)-5,21-dihydroxi-6,6′,7-trimethoxiflavanone, (-)-5,21-dihydroxi-6,6′,7,8-tetramethoxyflavanone are first abstracted. Foregoing flavonoids are identified on the basis of results of chemical transformations (acid and alkaline hydrolysis), data of IR, UV, 1Н-NMR and mass spectra, comparing of physical and chemical constants to literary information, and also direct comparing to the standards of flavonoids, abstracted from other types of Scutellaria L. It is set that in composition the flavonoids of Scutellaria adenostegia Briq. connections prevail with unsubstituted for the ring of В.
