Abstract:
OBJECTIVETo study the chemical components from dried roots of Zanthoxylum dimorphophyllum var. spinifoliun.
METHODThe chemical components were isolated by low pressure column chromatography and their structures were identified by spectroscopic methods.
RESULTFive 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).
CONCLUSIONThese compounds were isolated from the plant for the first time.
