GLAUCAFILIN, AN ACETOGENIN FROM ANNONA-GLAUCA

The seeds of Annona glauca yielded seven acetogenins. One of them, gla ucafilin, whose chemical structure was deduced by spectral and chemica l methods, is a new compound. Glaucafilin shares four hydroxyl groups, two of which are vicinal, with the rare erythro configuration. The si x known acetogenins identified were gigantetrocin A, goniothalamicin, annonacin A, annonacin, gigantecin and squamocin. Copyright (C) 1997 E lsevier Science Ltd.
