秋枫化学成分的研究

Chemical Constituents of Bischofia Javanica

利用各种色谱技术从秋枫(Bischofia javanica)的根中分离得到11个化合物。通过波谱学方法鉴定为3,4-二羟基苯乙醇(1),2-(3,4-dihydroxy)-phenylethyl-O-β-D-glucopyranoside(2),tachioside(3),isotachioside(4),儿茶素(5),表儿茶素(6),没食子儿茶素(7),4-羟基-2-甲氧基苯酚1-O-β-D-(6'-O-没食子酰基)葡萄糖苷(8),4-hydroxy-3-methoxyphenol-β-D-[6-O-(4-hydroxy-3,5-dimethoxylbenzoate)]glucopyranoside(9),maesopsin-6-O-glucopyranoside(10),β-香树脂醇乙酸酯(11)。所有化合物均为首次从该种植物中分离得到。

Eleven compounds were isolated from the roots of Bischofia javanica by various chromatographic techniques. By physical-chemical and spectral analysis, their structures were elucidated as 3,4-dihydroxypheny]ethyl alcohol （1） ,2- （3,4-dihydroxy） -phenylethyl-O-β-D-g]ucopyranoside （ 2 ）, tackioside （3）, isotachioside （4）, catechin （S7, epicatechin （6）, gallocatechin （ 7 ）, 4-hydroxy-2-methoxyphenol-l-O-β-D- （ 6＇-O-galloyl ） glucopyranoelde （ 8 ）, 4-hydroxy-3 -me- thoxypheno｜-β-D-C 6-0-（ 4-hydroxy-3,5-dimethoxylbenzoate ） ; glucopyranoside （ 9 ）, maesopsin-6-O-glucopyranoside （10） ,β-amyrin acetate （11）, respectively. All the compounds were isolated from this plant for the first time.
