Bioactive constituents from seeds of Persoon (Annonaceae).

Column chromatography led to the isolation and full characterization of -cerotoyltryptamine () previously described in a mixture of 5 compounds, asimicin () and -19-Carbomethoxykauran-17-oic acid () isolated from this species for first time alongside stigmasterol glycoside () and lacceroic acid (). The structures of the compounds were established by extensive EIMS, HRESIMS, 1 D and 2 D NMR studies. Compound and the extract AS were more potent inhibitors of ROS with IC values of 2.
