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