金钗石斛中的酚性成分(英文)

Phenolic components from Dendrobium nobile

目的对金钗石斛茎的化学成分进行研究.方法运用多种色谱学技术对金钗石斛的化学成分进行分离,并根据光谱数据鉴定化合物的结构.结果从该植物中分离得到12个酚性化合物,其结构分别为二氢松柏醇二氢对羟基桂皮酸酯（Ⅰ）,香草醛（Ⅱ）,罗布麻宁（Ⅲ）,对羟基苯甲醛（Ⅳ）,丁香醛（Ⅴ）,丁香酸（Ⅵ）,丁香乙酮（Ⅶ）,α-羟基丁香丙酮（Ⅶ）,松柏醛（Ⅸ）,二氢松柏醇（Ⅹ）,2-羟基苯丙醇（Ⅺ）和3-羟基-4-甲氧基苯乙醇（Ⅻ）.结论上述化合物均为首次报道从金钗石斛中分离得到,化合物Ⅰ,Ⅲ～Ⅻ为首次报道从石斛属植物中分离得到.

Objective To study the chemical constituents from the stems of Dendrobium nobile. Methods Compounds were isolated through various chromatographic techniques and identified by spectral data. Results Twelve phenolic compounds were obtained. Their structures were characterized as dihydroconiferyl dihydro-p-coumarate （Ⅰ）, vanillin （Ⅱ）, apocynin （Ⅲ）, p-hydroxybenzaldehyde （Ⅳ）, syringaldehyde （Ⅴ）, syringic acid （Ⅵ）, syringylethanone （Ⅶ）, α-hydroxypropiosyringone （Ⅷ）, coniferyl aldehyde （Ⅸ）, dihydroconiferyl alcohol （Ⅹ）, 2-hydroxyphenylpropanol （Ⅺ）, and 3-hydroxy-4-methoxyphenylethanol （Ⅻ）, respectively. Conclusion All above compounds are reported from this plant for the first time. Compounds Ⅰ and Ⅲ -Ⅻ are reported for the first time from the plants of Dendrobium Sw.
