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.
