Secondary metabolites of plants of the genus Scutellaria of the flora of Uzbekistan S. phyllostachya and S. cordifrons: isolation, chemical structure and biological activity

The aim of research work is isolation of the flavonoids from plants Scutellaria phyllostachya Juz. and Scutellaria cordifrons Juz., determining their chemical structures and pharmacological properties.
The objects of the research work are species of the genus Scutellaria phyllostachya Juz. and Scutellaria cordifrons Juz.
Scientific novelty of the research work:
26 flavonoids: 14 glycosides and 12 aglycons from the plants Scutellaria phyllostachya Juz. and Scutellaria cordifrons Juz. have been isolated;
it has been determined that 26 substances from the isolated substances belong to the flavones, 2 of them to new flavanones;
it has been established, that chemical structures of two new flavanones are -(+)-5,2'-dihydroxy-6,6',7 trimethoxyflavanone and (+)-5,2'-dihydroxy-6,6',7,8-
tetramethoxyflavanone);
