Two Cangorosin A Type Triterpene Dimers from Maytenus chuchuhuasca

Two new cangorosin A type triterpene dimers, which composed of two triterpene units jointed by two ether linkages between the A and B rings, were isolated from the Brazilian medicinal plant “xuxuá” (Maytenus chuchuhuasca). Structures of new isolates, xuxuasins A (1) and B (2), were established based...

Zusammenfassung:Two new cangorosin A type triterpene dimers, which composed of two triterpene units jointed by two ether linkages between the A and B rings, were isolated from the Brazilian medicinal plant “xuxuá” (Maytenus chuchuhuasca). Structures of new isolates, xuxuasins A (1) and B (2), were established based on several spectroscopic evidences.
