Abstract:

A series of 2D NMR techniques, including COSY, HMQC and HMBC, were applied to the assignments of all their carbon and proton signals of lililancifoloside A  (diosgenin 3-O- {O-α-L-rhamnopyranosyl(1→2)-O-[α-L-arabinopyr anosyl(1→3)]-β-D- glucopyranoside})  and ophiopogonin D′. The NMR charact eristics of steroidal saponins for diosgenin type were summaried. Lililancifolos ide A is a new compounds isolated from the bulbs of Lilium lancifolium Thunb . by  authors. Ophiopogonin D′is a known compound isolated from the title plant and  its carbon and proton signals were assigned for the first time.

Key words: lililancifoloside A, ophiopogonin D′, steroidal saponins, NMR, assignment
