OBJECTIVE: To study the chemical constituents of the dried roots of Zanthoxylum dimorphophyllumr. spinifolium and to find out the active constituents of the plant. METHOD: Modern chromatography was used to purify chemical constituents, and their structures were identified by various spectral methods. RESULT: Four compounds were isolated and identified as isopimpinellin (I), xanthoxyletin (II), 6-(2', 3'-dihydroxy-3'-methyl-butyl)-7-hydroxy-2H-1-benzopyran-2-one (III), 6-(2'-O-beta-D-glucopyranosyloxy, 3'-dihydroxy-3'-methybutyl)-7-hydroxy-2H-1-benzopyran-2-one (IV). CONCLUSION: All of the above compounds were isolated from the above mentioned plant for the first time.
