Abstract
Two novel stereoisomeric triterpene dimers, xuxuarines A alpha (1) and A beta (2), were isolated from a South American medicinal plant, ''xu xua'' (Maytenus chuchuhuasca Raymond-Hamet et Colas), and their struct ures and conformations were elucidated by spectroscopic, chemical evid ence and MD calculations.
