To investigate the chemical constituents of effective part of Oroxylum indicum which related to lowering LDLC action. The compounds were isolated with chromatography methods such as silica gel,polyamide and Sephadex LH-20. The structures were identified by physiochemical properties and spectral analysis. 14 compounds were isolated from 95% alcohol extract and elucidated as β-sitosterol( 1), hexadecanoic acid( 2), oroxin A( 3), oroxin B( 4), chrysin( 5), quercetin( 6),quercetin-3-Orutinoside( 7),5,4’-dihydroxy-3,6,7-trimethoxyflavone( 8), diosmetin( 9), geniposide( 10),isoorientin( 11), quercitroside( 12), apigenin( 13) and gallicacid( 14). Compounds 2,7 ~ 12 and 14 are reported from this plants for the first time.
