摘 要 ：目的:对刺异叶花椒Zanthoxylum dimorphophyllum var.spinifolum根的化学成分进行研究。方法:采用现代色谱分离技术进行化学成分的分离,运用波谱方法确定结构。结果:从中分离得到5个化合物,分别鉴定为5-甲氧基-7-羟基-6-(3′-甲基-2′,3′-二羟基丁基)-香豆素(Ⅰ),6-(3′-甲基-2′,3′-二羟基丁基)-7-甲氧基-8-(3″-甲基-丁-2″-烯基)-香豆素(Ⅱ),6-(3′-甲基-2′,3′-二羟基丁基)-7-羟基-8-(3″-甲基-丁-2″-烯基)-香豆素(Ⅲ),6-(3′-甲基-2′,3′-环氧丁基)-7-甲氧基-8-(3″-甲基-丁-2″-烯基)-香豆素(Ⅳ),7-甲氧基-8-(3′-甲基-丁-2′-烯基)-香豆素(Ⅴ)。结论:以上化合物均为首次从该植物中分得。

Abstract:Objective: To study the chemical components from dried roots of Zanthoxylum dimorphophyllum var.spinifolium. Method: The chemical components were isolated by low pressure column chromatography and their structures were identified by spectroscopic methods. Result: Five compounds were isolated and identified as 6-(2′ ,3′-dihydroxy-3′-methyl-butyl)-7-hydroxy-5-methoxy-2H-1-benzopy-ran-2-one (Ⅰ), 6-(2′, 3′-dihydroxy-3′-methyl-butyl)-7-methoxy-8-(3′-methyl-but-2′-enyl)-2H-1-benzopyran-2-one (Ⅱ), 6-(2′, 3′-dihy-droxy-3′-methyl-butyl)-7-hydroxy-2H-1-benzopyran-2-one (Ⅲ), 6-(2′, 3′-oxiranyl-3′-methyl-butyl)-7-methoxy-8-(3-methyl-but-2-enyl)-2H-1-benzopyran-2-one (Ⅳ) ,7-methoxy-8-(3′-methyl-but-2′-enyl)-2H-1-benzopyran-2-one (Ⅴ). Conclusion: These compounds were isolated from the plant for the first time.
