Flavonoids from Teucrium fruticans L.

From aerial parts of <em>Teucrium fncticans</em> 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.
