摘要
目的:研究紫葳科Bignoniaceae植物木蝴蝶Oroxylum indicum种子的化学成分.方法:采用硅胶柱色谱、Sephadex LH-20凝胶柱色谱等手段进行分离纯化,通过化合物的理化常数和波谱数据鉴定其结构.结果:从木蝴蝶种子的95％乙醇提取物中分离并鉴定了20个化合物,分别为木蝴蝶苷A(1)、木蝴蝶苷B(2)、白杨黄素(3)、黄芩苷元(4)、槲皮素(5)、芹菜素(6)、山柰酚(7)、槲皮素-3-O-阿拉伯吡喃糖苷(8)、羽扇豆醇(9)、2α,3β-二羟基羽扇豆醇(10)、赤松素(11)、二氢赤松素(12)、胆甾-5-烯-3,7-二醇(13)、连翘环己醇(14)、异连翘环己醇(15)、zarzissine(16)、(E)-银松素-3-O-β-D-吡喃葡萄糖苷(17)、腺苷(18)、β-谷甾醇(19) 、β-胡萝卜苷(20).结论:化合物11-13,15～18为首次从木蝴蝶植物中分离得到,其中除化合物18外,其余6个化合物均为首次从紫葳科植物中获得.
Abstract
Objective:To study the chemical constituents in the seeds of Oroxylum indicum.Method:Twenty compounds were isolated and purified by silica gel,and Sephadex LH-20 column chromatography,and their structures were determined by spectroscopic analysis including NMR and MS.Result:Twenty compounds were isolated and identified as oroxin A (1),oroxin B (2),chrysin (3),baicalein (4),quercetin (5),apigenin (6),kaempferol (7),quercetin-3-O-ara-binopyranoside (8),lupeol (9),lup-20 (29)-ene-2α,3β-diol (10),pinosylvin (11),dihydropinosylvin (12),cholest-5-ene-3,7-diol (13),rengyol (14),isorengyol (15),zarzissine (16),(E)-pinosylvin-3-O-β-D-glucopyranoside (17),adenosine (18),sitosterol (19) and daucosterol (20).Conclusion:Compounds 11-13 and 15-18 were obtained from the genus Oroxylum for the first time,and except compound 18,the remaining 6 compounds were obtained from the family Bignoniaceee for the first time.
