The structural elucidation of seven related oxypregnane-oligoglycosides stephanosides K (1), L (2), M (3), N(4), O (5), P (6), and Q (7) from the fresh stem of Stephanotis lutchuensis var. japonica (Asclepiadaceae) was achieved through on a detailed study of their high-field ¹H- and ¹³C-NMR spectra. The results show that all the sugars are β (1→4)-linked. The aglycones of stephanosides K, M, and O, and stephanosides L, N, and P were identified as 12-O-cinnamoyl-20-O-(E)-2-methyl-2-butenoyl, and 12-O-cinnamoyl-20-O-nicotinoyl derivatives of(20S)-pregn-6-ene-3β, 5α, 8β, 12β, 14β, 17β, 20-heptaol, respectively. The aglycone of stephanoside Q was 12-O-cinnamoyldeacetylmetaplexigenin (kidjoranin).
