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 Hems1. 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'-dihydroxy-3'-methybutyl)-7-(beta-D-glucopyranosyloxy)- 2H-1-benzopyran-2-one (II), hexacosanoci acid (III), aurepten (IV), 6-6'-O-(-deoxy-alpha-L-mannopyranosyl)-beta-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.
