摘要
目的 研究木蝴蝶种子的黄酮类化学成分。方法 采用硅胶、C18反相硅胶、Sephadex LH-20凝胶等色谱技术进行分离纯化，通过MS、1H-NMR、13C-NMR等波谱方法鉴定化合物的结构。结果 从中分离得到15个化合物，分别鉴定为白杨素(1，黄芩苷元(2，千层纸素A(3，4′-羟基黄芩素(4，白杨素7-O-β-D-葡萄糖苷(5，黄芩苷元 7-O-β-D-葡萄糖苷(6，白杨素7-O-β-D-葡萄糖醛酸苷(7，白杨素8-C-β-D-葡萄糖苷(8，异槲皮苷(9，山柰酚7-O-β-D-葡萄糖苷(10，白杨素 7-O-β-D-葡萄糖醛酸乙酯苷(11，刺槐素(12，去甲汉黄芩素(13，异鼠李素(14，高车前素(15。结论 化合物8～14为首次从该植物中分离得到。
Abstract
OBJECTIVE To study the flavanoids from the seeds of Oroxylum indicum(L.Vent. METHODS The constituents were isolated and purified by repeated column chromatography on silica gel，C18 reverse-phase silica gel and Sephadex LH-20. MS，1H-NMR，13C-NMR spectral techniques were used for structural elucidation. RESULTS Fifteen flavonoids were obtained from Oroxylum indicum(L.Vent and their structures were identified as chrysin(1，baicalein(2，oroxylin A(3，scutellarein(4，aequinoctin(5，oroxin A(6，chrysin 7-O-β-D -glucuronide(7，chrysin 8-C-β-D-glucopyranoside(8，isoquercetin(9，kaempferol 7-O-β-D- glucopyranoside(10，chrysin 7-O-β-D-glucuronide ethyl ester(11，acacetin(12，norwogonine(13，isorhamnetin(14and hispidulin(15，respectively. CONCLUSION Compound 8-14 were obtained from Oroxylum indicum(L.Vent for the first time.
