Two new rearranged lanosterol trisaccharides, peruvianosides A (1) and
B (2), were isolated from fresh bulbs of Scilla peruviana. Their stru
ctures were established mainly by extensive 2D NMR analysis. Peruviano
side A (1) showed an inhibitory activity on cyclic adenosine monophosp
hate (AMP) phosphodiesterase.
