Phytochemical investigation on the aerial parts of Melodinus hemsleyanus diels (Jahrb, Syst, 1995) led to the isolation and identification of 27 compounds, including fifteen aspidosperma-type alkaloids (1-15), four quinoline-type alkaloids (16-19), three quebrachamine-type alkaloids (20-22), and five eburna-type alkaloids (23-27). The structure of compound 1 was elucidated by means of spectroscopic analysis, including HRESIMS, and 1D and 2D NMR experiments. Compounds 1-2, 6, 10, 12, 13, 15, 16 and 20-27 are herein reported for the first time from the studied plant, while the compounds 1-2 and 21 have not previously been recorded in the genus Melodinus. The aspidosperma-type monoterpenoid indole alkaloids in M. hemsleyanus could serve as chemotaxonomic markers.
