Abstract
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 H-1- and C-13-NMR, C-13,H-1-HETCOR, H-1,H-1-2D-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).
