Two new flavonoids from the roots of Scutellaria baicalensis.

Abstract:

:One new flavone, 5,7-dihydroxy-8,2',3',6'-tetramethoxyflavone (1), and one new flavonol, 5,7,6'-trihydroxy-2'-methoxyflavonol (2), were isolated from the roots of Scutellaria baicalensis, and their structures were elucidated on the basis of extensive spectroscopic evidences, especially 1D and 2D NMR and HR-ESI-MS experiments. The structure features of these new compounds lie in the substitution at both C-2' and C-6' positions of B-ring by hydroxyl or methoxyl groups.
