(25S)-27-hydroxypenogenin-3β-O-α-L-rhamnopyranosyl-(1→4)-[O-α-L-rhamno-pyranosyl-(1→2)]-O-β-D-glucopyranoside (1) and polyphylloside III (2) were isolated from Trillium tschonoskii by column chromatography. One-dimensional and two-dimensional NMR techniques, including 1H NMR, 13C NMR, DEPT, HSQC, HMBC and 1H-1H COSY, were used to elucidate the structures of these compounds. 13C NMR and 1H NMR chemical shifts of the two compounds were completely assigned.
