Abstract The structure of diodantunezone has been revised from 8- to 5-hydroxynaphtho[2,3- b ]furan-4,9-quinone. Both it and the 8-hydroxy isomer, isodiodantunezone, are present in Lantana achyrantifolia and L. camara . The latter also contains 6- and 7-methoxydiodantunezone, 6-and 7-methoxyisodiodantunezone, and 6- and 7-methoxynaphtho[2,3- b ]furan-4,9-quinones.
