Three benzylisoquinoline alkaloids, reticuline, coclaurine, and N-acetyl norjuziphine, where isolated from the stem bark of Ocotea duckei, the calix yielded laurelliptine, an aporphine alkaloid. These substances were isolated by chromatographic methods and identified by 1H and 13C NMR spectroscopy with the aid of 2-D techniques such as COSY, NOESY, HMQC and HMBC. Comparison with literature data was also helpful.
