旋蒴苣苔的化学成分(英文)

目的:研究旋蒴苣苔全草(Boea hygrometrica(Bunge.)R.Br.)的化学成分。方法:利用Diaion HP-20,Toyopearl HW-40,硅胶等柱色谱技术进行分离纯化,根据化合物的光谱数据和理化性质鉴定结构。结果:分离并鉴定了7个化合物的结构,即5,7,3',4'-四羟基-6-甲氧基-8-C-β-D-木糖-(1→2)]-β-D-葡萄糖黄酮碳苷(1),对羟基苯乙醇(2),3,4-二羟基苯乙醇(3),罗布麻宁(4),阿魏酸(5),1′-O-β-D-(3,4-二羟基苯乙基)-6′-O-咖啡酰基-β-D-芹菜糖(1→3′)-葡萄糖苷(6),龙胆酸(7)。结论:化合物1为新化合物,化合物2-7为首次从该植物中分离得到。

Chemical Constituents of Boea hygrometrica

AIM：To study the chemical constituents of Boea hygrometrica （Bunge.） R.Br..METHODS：The compounds were isolated and purified by Diaion HP-20,Toyopearl HW-40,silica gel column chromatography and the structures were identified on the basis of spectral data and physiochemical properties.RESULTS：Seven compounds were obtained and identified as 5,7,3＇4＇-tetrahydroxy-6-methoxy-8-C-β-D-xylopyranosyl-（1→2）]-β-D-glucopyranosyl flavone （1）,p-hydroxy phenethylalcohol （2）,3,4-dihydroxy phenethylalcohol （3）,apocynin （4）,ferulic acid （5）,1＇-O-β-D-（3,4-dihydroxy）-ethyl-6＇-O-trans-caffeoyl-β-D-apiofuranosyl-（1→3＇）- glucopyranoside （6）,gentisic acid （7）.CONCLUSION：Compound 1 was a new c-glycoside flavonal and compounds 2-7 were isolated from this plant for the first time.
