Abstract
Nine regioisomeric and stereoisomeric triterpene dimers, namely xuxuarine Falpha (1), isoxuxuarine Falpha (2; cangorosin B), 7,8-dihydroisoxuxuarine Falpha (3), isoxuxuarine Gbeta (4), 7,8-dihydroisoxuxuarine Galpha (5), isoxuxuarine Ebeta (6), 7alpha-hydroxyisoxuxuarine Ealpha (7), 7',8'-dihydroxuxuarine Aalpha (8), and 7',8'-dihydroxuxuarine Dbeta (9), were isolated from the Brazilian medicinal plant "xuxuá" (Maytenus chuchuhuasca). Their structures have been elucidated based on several spectroscopic analyses including 2D-NMR experiments, MS spectra and CD spectral studies.Entities:
