RESUMO

A chemical investigation of Anaxagorea dolichocarpa Sprague & Sandwith, a member of Annonaceae family, was carried out. The ethanolic extract from the roots of this plant led, by chromatography tecniches, to isolation of the new azaphenanthrene alkaloids dolichocarpine (1) and 9-methoxyeupolauramine (2), besides the known alkaloids eupolauramine (3), 3-methoxyeupolauridine (4), eupolauramine (5) and 4-methylsampangine (6). The structures of isolated compounds were established by 1D and 2D NMR, HRESIMS, tandem MSn and IR data. The cytotoxicity of compounds 1 - 5 was evaluated against HCT-116 (human colorectal carcinoma) and L929 (murine fibroblast) cell lines.
