Flavonoids from Teucrium fruticans L.

Abstract

From aerial parts of Teucrium fruticans L. three flavonoids were isolated and identified as 5-hydroxy-6, 7, 3′, 4′-tetramethoxyflavone, 5, 4′-dihydroxy-6, 7, 3′-trimethoxyflavone (cirsilineol) and 5, 4′-dihydroxy-6, 7-dimethoxyflavone (cirsimaritin). The former compound was found to be a predominant flavone aglycone constituent of the plant material. This is the first report on the isolation of flavonoids from the plant.
