Flavonoids of Scutellaria ocellata and S.nepetoides

摘要

The known flavonoids oroxylin A, wogonin, apigenin, 3,7,4'-trihydroxyflavone, cinaroside, baicalin, and wognoside were isolated from the aerial part of Scutellaria ocellata Juz.; apigenin-7-O-beta-D-glucuronide, norwogonosid,e scutellarin, and the new flavoneglycoside nepetoside A, 5,8-dihydroxy-7-O-beta-D-galacturonidopyranosylflavone, from the roots of Scutellaria nepetoides M. Pop. The structure of the last is established using chemical transformations and spectral data.
