Abstract
Twelve compounds were isolated from the ethyl acetate soluble portion of the 70% hydroalcoholic extract from the leaves of Zanthoxylum nitidum (Roxb.) DC. All of the compounds were determined on the basis of UV, IR, NMR and MS and comparison with literature. Among them, compounds 4, 7, 10 and 12 were first acquired from Rutaceae, compound 2 was isolated from the genus of Zanthoxylum for the first time and compounds 1, 3, 6, 9, 11 were isolated from Z. nitidum for the first time. Our present study exhibited the taxonomic relationships between Z. nitidum and other species in the same genus; those between Rutaceae and other families. Furthermore, we have summarized the chemotaxonomic significance of these compounds in Rutaceae and Zanthoxylum.
