【摘要】 为研究贡山八角枝叶的化学成分,我们利用色谱法对贡山八角(Illicium wardii A.C.Smith)枝叶95%乙醇提取物中的化学成分进行分离。利用核磁共振、质谱、红外等方法对分离得到的单体化合物进行结构鉴定,从贡山八角枝叶中分离得到了15个化合物,分别是β-谷甾醇(1)、二十六烷(2)、红花八角醇(3)、三十四烷醇(4)、异鼠李素-3-O-β-D-芸香糖苷(5)、acernikol(6)、subamone(7)、苔色酸甲酯(8)、扁柏脂内酯(9)、厚朴酚(10)、原儿茶酸(11)、异红花八角醇(12)、vitrifol A(13)、右旋二氢去氢双松柏醇(14)、左旋马尾松树脂醇(15)。其中化合物2~15首次从该植物中分离得到,化合物7和15为首次从该科植物中分离得到。更多还原

【Abstract】 To investigate chemical constituents of the branches and leaves of Illicium wardii A. C. Smith. Chemical constituents were isolated using column chromatography from 95% ethanol extracts of the branches and leaves of I. wardii.Their structures were elucidated by NMR,IR and MS techniques. Fifteen compounds were obtained and identified as β-sitosterol(1),hexacosane(2),dunnianol(3),tetratriacontanol(4),isorhamnetin-3-O-β-D-rutinoside(5),acernikol(6),subamone(7),methyl-β-orsellinate(8),hinokinin(9),magnolol(10),protocatechuic acid(11),isodunnianol(12),vitrifol A(13),(+)-dihydrodehydrodiconiferyl alcohol(14) and(-)-massoniresinol(15). Compounds 2-15 were obtained from this plant firstly,and compounds 7 and 15 were found from Illiciaceae family firstly.更多还原
