The Amaryllidaceae alkaloids are well-known chemotaxonomic marker possessing a diverse array of biological activities including antitumoral, antiviral, antiparasitic, psychopharmacological and interaction with the cholinesterase enzymes. The indigenous Brazilian species Worsleya procera is the only representative of the Worsleya genus and might be found around the Province of Rio de Janeiro, in Brazil. In this work, the bulbs of W. procera have been submitted to alcoholic maceration and classical acid-base alkaloid extraction. The alkaloid-enriched fractions were purified by means of chromatography techniques and seven compounds were obtained which were analyzed particularly by GC-MS, HRESIMS and NMR tecniques. The analysis of spectroscopic data allowed to identify two new dinitrogenous alkaloids obliquine N-oxide (1) and 3-epi-obliquine N-oxide (2) along with the known compounds 3-methoxy-8,9-methylenedioxy-3,4-dihydrophenanthridine (3), obliquine (4), plicane (5), albomaculine (6) and 3-epi-macronine (7) (Figure 1). The absolute stereochemistry of the compounds 1, 2 and 3 were elucidated by 2D-NMR spectroscopy. The complete NMR data for 1, 2 and 3 are also reported herein. The identification of others components as well as the biological evaluation of the isolated compounds are still in process.
