Coumarins from root of Zanthoxylum dimorphophyllum var. spinifolium / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical components from dried roots of Zanthoxylum dimorphophyllum var. spinifoliun.</p><p><b>METHOD</b>The chemical components were isolated by low pressure column chromatography and their structures were identified by spectroscopic methods.</p><p><b>RESULT</b>Five compounds were isolated and identified as 6-(2', 3'-dihydroxy-3'-methyl-butyl)-7-hydroxy-5-methoxy-2H-1-benzopyran-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'-dihydroxy-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).</p><p><b>CONCLUSION</b>These compounds were isolated from the plant for the first time.</p>
