Bonnet, Dieudonné Emmanuel PegnyembThe present study deals with the isolation and the characterization of the chemical constituents from the leaves of Anthonotha macrophylla (Leguminosae). Using various chromatographic techniques (TLC, CC, HPLC), the methanolic extract of the leaves of Anthonotha macrophylla yielded one new alkaloid (1) as well as six known compounds amongst which an alkane (2), isolated for the first time from a natural product, an ester of fatty acid (3), two isocoumarines (4–5), a sterol (6) and a disaccharide (7). Their structures were elucidated using spectroscopic technics including extensive 1-D and 2-D NMR, HR-SM experiments.
