New aporphine alkaloids of Ocotea minarum.
Fourteen aporphine alkaloids were isolated from the leaves of a Brazilian Lauracea, Ocotea minarum Nees (Mez). The known alkaloids were identified through their physico-chemical properties as: leucoxylonine (VII), dicentrine (IV), ocoteine (V), leucoxine (VI), ocopodine (VIII), predicentrine (IX), dicentrinone (XIV) and thalicminine (XV). Six new aporphine alkaloids were also isolated: ocotominarine (I), ocominarine (III), nor-leucoxylonine (XI), iso-oconovine (xii), 4-hydroxydicentrine (XIII) and ocominarone (XVI). Their structures were determined using spectroscopic methods and chemical correlations.
