Abstract:
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.
