Three new homoerythrina alkaloids were isolated from the leaves of Phelline brachyphylla: homoerythratine (3), phellinine (6) and O-méthyl phellinine (7). Their structures were established by spectral analysis, especially by pmr at 400 MHz and confirmed through a chemical correlation, in the case of homoerythratine. © 1982, American Chemical Society.
