M. Kuroda et al., STRUCTURE OF A NOVEL 22-HOMO-23-NORCHOLESTANE TRISACCHARIDE FROM ORNITHOGALUM-SAUNDERSIAE, Tetrahedron letters, 34(38), 1993, pp. 6073-6076
A novel 22-homo-23-norcholestane trisaccharide, which showed an unique
inhibitory pattern on cyclic AMP phosphodiesterase, was isolated from
the bulbs of Ornithogalum saundersiae. The structure was determined b
y extensive 2D NMR analysis and hydrolysis.
