ABSTRACT
Oroxylum indicum was a traditional Chinese medicine. In order to study the chemical constituents from the seed of O. indicum, the chemical constituents of 80% methanol extract of seeds of O. indicum were subjected to chromatography on silica gel, Sephadex LH-20, and preparative HPLC, leading to the isolation of eleven compounds. The structures were identified by various spectroscopic data including ESI-MS, 1H-NMR and 13C-NMR data as oroxin B (1), chrysin (2), baicalein (3), neglectein (4), quercetin-3-O-β-D-galactopy ranoside (5), quercetin-7-O-β-D-glucopyranoside (6), 2α,3β-dihydroxylluPeol (7), lupeol (8), rengyol (9), β-sitostero (10), and stigmasterol (11). Among them, compound 5 were firstly obtained from O. indicum.
