[Studies on chemical constituents in stems of Zanthoxylum dissitum].

ABSTRACT

OBJECTIVE: To study the chemical constituents from the stems of Zanthoxylum dissitum. METHOD: Column chromatography on macroporous resin and silica gel, and spectral analysis were used to isolate and elucidate the constituents. RESULT: Seven compounds were isolated and identified as 5,8-dimethoxyethane-3,4-epoxy-furanocoumarin (1), isoimpinellin (2), beta-sitosterol (3), lupeol (4), neohesperidin (5), beta-daucosterol (6), ursolic acid (7). CONCLUSION: All above the compounds were isolated from the plant for the first time and the compound 1 is a new compound.
