The structures of 22-hydroxy furostanol bisglycosides, T-e (2), T-j (3) and T-h (4), which are recognized as real substances of "nolonin"and correspond to proto-type of pennogenin glycosides, have been substantiated by 13C nuclear magnetic resonance spectra. Moreover, two new sapogenols, G-I and G-II, have been isolated from the hydrolysate by using H2SO4 in 50% EtOH of the MeOH extractives of the underground parts of Trillium kamtschaticum PALL. and their structures could be deduced as the formulae 8 and 9, respectively.
