title: Aspidosperma-type Alkaloids from Melodinus suaveolens.
abstract: Three new aspidosperma-type alkaloids, 3-oxo-11-hydroxytabersonine (2), 1 1-hydroxytabersonine N-oxide (3) and 11-methoxytabersonine N-oxide (4), along with three known ones were isolated from the twigs and leaves of Melodinus suaveolens. The structures of the new compounds were elucidated by using spectroscopic methods, and circular dichroism experiments. The known compounds were identified by comparing their spectroscopic data with those reported in the literature.
