Abstract

Seven known Benzylisoquinoline alkaloids, Papraline 1, (+)-norcinnamolaurine 2, (+)-codamine 3, (+)-6-methoxy-1-(3'-methoxybenzyl)-N-methyl-7-isoquinolinol 4, (+)-reticuline N-oxide 5, (+)-reticuline 6 and (-)-N-methylisococlaurine 7 were isolated from bark of Cryptocarya rugulosa. A combination of 1D-NMR (1H, 13C, DEPT, NOE), 2D-NMR (COSY, NOESY, HMQC, HMBC), MS (HRESI+, FAB+ and EI) spectroscopy used to elucidate the structure.

Abstract

Isolation, identification and characterization of the compounds isolated from the bark of Cryptocarya ferrea yielded three known aphorpine alkaloids. They are (-)-O-methylisopiline 1, (+)-norlirioferine 2 and (+)-lirioferine 3. Structural elucidation was established through several spectroscopic methods, such as 1D-NMR (1H, 13C, DEPT, NOE), 2D-NMR (COSY, NOESY, HMQC, HMBC), UV, IR, and MS and comparison with the published data.
