摘要
目的 研究辛夷(Magnolia biondii Pamp.)的化学成分.方法 利用Diaion HP-20,Toyopearl HW-40,硅胶柱及半制备液相等多种色谱技术进行分离纯化,根据化合物的理化性质和光谱数据鉴定结构.结果 分离并鉴定了14个化合物的结构,分别为香草酸-4-O-β-D-葡萄糖苷(1),3-甲氧基-4-羟基苯-1-O-β-D-葡萄糖苷(2),香草酸甲酯(3),咖啡酸(4),3,4,5-三甲氧基苯-1-O-β-D-葡萄糖苷(5),苄基-O-β-D-葡萄糖苷(6),苄基-O-β-D-半乳糖苷(7),紫丁香苷(8),香草酸葡萄糖酯(9),香草酸(10),1'-(3,4-二羟基肉桂酰)环戊烷-2',3'-二醇(11),东莨菪苷(12),7-甲氧基香豆素-6-O-β-D-葡萄糖苷(13)和莨菪亭(14).结论 化合物1～9,11 ～13为首次从该植物中分离得到.
Abstract
OBJECTIVE To study the chemical constituents of Magnolia biondii.Pamp.METHODS The compounds were isolated and purified by Diaion HP-20, Toyopearl HW-40, silica gel column chromatography and semi-preparative HPLC and so on.The structures were elucidated on the basis of spectral data and physiochemical properties.RESULTS Fourteen compounds were isolated and identified as 4-O-β-D-glucopyranosylvanillic acid (1), tachinoside (2), methyl 4-hydroxy-3-methoxybenzoate (3), caffeic acid(4), 3 , 4 ,5-trimethoxyphenyl-β-D-glucopyranoside (5) , benzyl-O-β-D-glucopyranoside (6) , benzyl-O-β-D-galactopyranoside (7) ,syringin (8), vanillic acid glucosyl ester (9), vanillic acid (10), 1 '-(3,4-dihydroxycinnamoyl) cyclopentane-2', 3 '-diol (11), scopolin (12) ,7-methoxycoumarin-6-O-β-D-glucopyranoside(13), and scopoletin(14).CONCLUSION Compounds 1-9 and 11-13 areisolated from this plant for the first time.
