STUDIES ON THE CHEMICAL CONSTITUENTS OF ZANTHOXYLUM DIMORPHOPHYLLUM HEMSL. VAR SPINIFOLIUM RHED. ET WILS

AIM To study the chemical components from the dried roots of Zanthoxylum dimorphophyllum Hemsl. var spinifolium Rhed. et Wils. METHODS Modern chromatography was used to isolate chemical components and the compounds isolated from Zanthoxylum dimorphophyllum Hemsl. var spinifolium Rhed. et Wils were identified by various spectral methods. RESULTS Five compounds were isolated and identified as 6-(2′,3′-dihydroxy-3′-methybutyl)-7-acetoxy-2H-1-benzopyran-2-one (I), 6-(2′,3′-ihydroxy-3′-methybutyl)-7-(β-D-glucopyranosyloxy)-2H-1-benzopyran-2-one (II), hexacosanoci acid (III), aurepten (IV), 6-6′-O-(-deoxy-α-L-mannopyranosyl)-β-D-benzopyran-4-one (V). CONCLUSION All of the above compounds were isolated from the plant for the first time, among them, I is a new compound.
