Chemical examination of the aerial parts of Bocconia arborea (Papaveraceae), a plant used in traditional medicine, led to the characterization of (±)-6-acetonyldihydrosanguinarine (1), (±)-6acetonyldihydrochelerythrine (2), (±)-6-methoxydihydrochelerythrine (3), (±)-sanguidimerine (4), chelidimerine (5), and the novel constituents (±)-bocconarborine A ((6R,6’S + 6S ,6’R)-13-(6-hydrosanguinariny...

A novel isoquinolinone alkaloid, iseluxine (1), has been isolated from the epigeal parts of Iseia luxurians (MORIC.) O'DONELL (Convolvulaceae), a climber indigenous to the tropical Americas. Structural elucidation was achieved by HRMS, 1H NMR, 13C NMR, and HMBC spectroscopy. N- and/or O-methyl derivatives of 1 are already known from certain Magnoliidae families, e.g., the Fumariaceae, the Laura...

Sanguinaria canadensis L., commonly known as bloodroot, red puccoon, Indian paint, redroot, pauson, or tetterwort, is found throughout most of North America east of the Rocky Mountains (Reed 1999). This herbaceous perennial is a member of the Papaveraceae (poppy family) (Reed 1999).
