Flavonoids from the Stem-bark of Oroxylum indicum

Two new flavonoid compounds, 8,8'-bisbaicalein 1 and baicalein-7-O-caffeate 2 along with six known flavonoids, baicalein, chrysin, scutellarein, 6-hydroxyluteolin, 6-methoxyluteolin and baicalein-7-Oglucoside and have been isolated from the stem-bark of Oroxylum indicum (Bignoniaceae) and identified on the basis of spectroscopic and chemical studies. 6-Hydroxyluteolin and 6-methoxyluteolin are reported for the first time from this plant.
