title: One new flavonoid from Oroxylum indicum.
abstract: One new flavonoid, 5,6,7-trimethoxyflavone-8-O-β-D-glucopyranoside (1), along with six known compounds 2-7, was isolated from Oroxylum indicum. Their structures were determined on the basis of spectral data. The antibacterial activities of compounds 1-4 were studied. Compounds 1 and 3 showed medium antibacterial activity against Staphylococcus aureus with MIC/MBC at 32-128 μg/ml.
