Glaucanetin and 10-Hydroxy-Glaucanetin, Two New Acetogenins fromAnnona Glauca

Abstract
The seeds of Annona glauca have yielded six Annonaceous acetogenins. Two of them, glaucanetin (1) and 10-hydroxy-glaucanetin (2), whose chemical structures were deduced by NMR and mass spectroscopic methods, are new compounds. Molvizarin (3), parviflorin (4), annoglaucin (5) and 10-hydroxy-asimicin (6) were also isolated.
