A Contribution to the Phytochemistry of Zanthoxylum tessmannii1.

Root bark extracts of ZANTHOXYLUM TESSMANNII (Engl.) Ayafor COMB. NOV. (Syn. FAGARA TESSMANNII Engl.) yielded, besides chelerythrine, dihydrochelerythrine, fagaramide and lupeol previously reported from this taxon, ten other compounds viz:nitidine, dihydronitidine, 9-methoxychelerthrine, gamma-fagarine, skimmianine, arctigenin methylether, savinin and a mixture of campesterol, beta-sitosterol and stigmasterol. The implications of the present results for the taxonomic position of ZANTHOXYLUM TESSMANNII is discussed.
