ResumoTrês alcalóides benzilisoquinolínicos, reticulina, coclaurina e N-acetilnorjuzifina foram isolados das cascas de caule de Ocotea duckei; do cálice foi isolado laureliptina, um alcalóide do tipo aporfínico. Essas substâncias foram isoladas por métodos cromatográficos e identificadas por espectroscopia de 1 H e 13 C NMR com o auxílio de técnicas 2-D como as de COSY, NOESY, HMQC e HMBC. Comparações com os dados de literatura foram também realizadas. AbstractThree 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 1 H and 13 C NMR spectroscopy with the aid of 2-D techniques such as COSY, NOESY, HMQC and HMBC. Comparison with literature data was also helpful.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
