OBJECTIVE:

To study the chemical constituents of Zanthoxyli Cortex.

METHODS:

The chemical constituents were isolated and purified by silica gel and HP-20, MCI gel, Sephadex LH -20 column chromatography, RP-18 and PTLC. Their structures were elucidated by the analysis of spectral data and chemical properties.

RESULTS:

Ten compounds were isolated from EtOAc extract and their structures were identified as: asarinin (I), fargesin (II), eudesmin (III), (1R, 2R, 5R, 6S)-2-(3,4-dimethoxyphenyl)-6-(3,4-dihydroxyphenyl)-3,7-dioxabicyclo[3.3.0]-octane(IV), dimethoxysamin(V), rel-(1R,5R,6S)-6-(3,4-dimethoxyphen-yl)-3,7-dioxabicyclo-[3.3.0]-octan-2-one(VI), Magnone A(VII), beta-sitoste-rol( VIII), beta-armyrin(IX), beta-amyrone(X).

CONCLUSION:

These compounds isolated from Zanthoxyli Cortex's Ethyl acetate extract are all known compounds. Fargesin(II) and beta-amyrone(X) are isolated from Zanthoxyli Cortex for the first time.
