木蝴蝶化学成分研究

Study on Chemical Constituents from Oroxylum indicum(L.)Vent.

本文对木蝴蝶Oroxylum indicum(L.)Vent.种子的化学成分进行了研究,以85%乙醇加热回流提取木蝴蝶成熟种子,提取物经柱层析和重结晶手段分离,最终得到10个化合物,根据波谱学手段和理化性质,鉴定其结构分别为木蝴蝶苷B(1),木蝴蝶苷A(2),白杨黄素(3),白杨黄素-7-O-双葡萄糖苷(4),白杨黄素-7-O-β-吡喃半乳糖醛酸苷(5),芹菜素(6),羽扇豆醇(7),2α,3β-二羟基羽扇豆醇(8),豆甾醇(9),油酸(10),其中,化合物6～9为首次从木蝴蝶属植物中分得。

The chemical constituents in the seeds of Oroxylum indicum（L.）Vent.was studied in this paper.The compounds were separated and purified by column chromatography and recrystallization,whose structures were established by spectroscopic methods.Ten compounds were isolated from Oroxylum indicum（L.）Vent.at last,and their structures were identified as Oroxin B（1）,Oroxin A（2）,Chrysin（3）,Chrysin-7-O-β-diglucoside（4）,Chrysin-7-O-galactopyranuronoside（5）,Apigenin（6）,Lupeol（7）,2α,3β-dihydroxyllupeol（8）,Stigmasterol（9）,Oleic acid（10）.Among them,compounds 6,7,8 and 9 were isolated from the plants in this genus for the first time.
