Abstract
The phytochemical study of Zanthoxylum rhoifolium apolar and medium polarity stem bark and leaf extracts afforded 29 compounds, including three new sesquiterpenes (1 - 3: ) and one new α-ionone glycoside (4: ). All compounds were characterized by means of 1D and 2D NMR and HRESIMS data. Furthermore, a precise structural analysis was performed, employing a combined density functional theory (DFT)/NMR approach to elucidate the compounds configurations. The crude extracts were then tested against a panel of gram-positive and gram-negative bacteria by broth dilution methods to determine their minimal inhibitory concentration. In these experimental conditions, no interesting antimicrobial activity was observed.
