Notes:
A new alkaloid, 4-hydroxy-5-methoxycanthin-6-one (1), has been isolated from Picrasma quassioides (Simaroubaceae), and its structure has been determined by high-field 1H- and 13C-NMR, 13C,1H-HETCOR, 1H,1H-2D-COSY, and NOE-difference spectra. Previous data, interpreted by other workers as being from this compound, is instead tentatively reassigned to another new alkaloid structure, 4-hydroxy-3-methylcanthine-5,6-dione (2).
