Abstract
New geometric and stereoisomeric triterpene dimers, 7,8-dihydroisoxuxu arine E alpha (2), xuxuarines F beta (3), G alpha (4) and G beta (5), along with a known compound, scutidin alpha A (1), were isolated from the South American medicinal plant ''xuxua'' (Maytenus chuchuhuasca RA YMOND-HAMET et COLAS). Their structures were determined on the basis o f spectroscopic evidence including CD spectral studies.
