野八角化学成分的研究

摘要

de-4'-O-methylyangambin (1),fargesin (2),3'-O-demethylepipinoresionl (3),lariciresinol dimethyl ether (4),dehydrodieoniferyl alcohol (5),myricetin-3-O-α-L-rhamnoside (6),kaempferol (7),quercetin (8),kaempferol-3-O-α-L-rhamnopyranoside (9),quercetin-3-O-oα-L-rhamnopyranosyl (1→6)-β-D-glucopyranoside (10) were isolated from the 95％ ethanol extract of Illicium simonsii.The structures of 1 10 were elucidated by spectroscopic methods including 1H-NMR,13C-NMR and ESIMS.In addition,compounds 1-3 were isolated from Illicium for the first time.%综合运用各种色谱分离技术对野八角果实的95％乙醇提取物进行化学成分研究,利用各种波谱技术确定化合物的结构.该研究从野八角果实中分离得到10单体成分,分别鉴定为:de-4'-O-methylyangambin (1)、辛夷脂素(2) 3'-O-demethylepipinoresionl (3)、lariciresinol dimethyl ether (4)、去氢双松柏醇(5)、杨梅树皮素-3-O-cα-L-鼠李糖苷(6)、山柰酚(7)、槲皮素(8)、山柰素3-O-α-L-鼠李糖苷(9)、槲皮素-3-O-α-L-吡喃鼠李糖基(1→6)-B-D-吡喃葡萄糖苷(10).其中,化合物1-3为首次从八角属中分离得到.
