[Coumarins from root of Zanthoxylum dimorphophyllum var. spinifolium].
OBJECTIVE
To study the chemical components from dried roots of Zanthoxylum dimorphophyllum var. spinifoliun.


METHODS
The chemical components were isolated by low pressure column chromatography and their structures were identified by spectroscopic methods.


RESULTS
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).


CONCLUSIONS
These compounds were isolated from the plant for the first time.
