Two steroidal glycosides, SL-1 (1) and SL-0 (2), and an additional steroid-alkaloidal glycoside, SL-2, were isolated from the stem parts of Solanum lyratum THUNB. (Solanaceae). Among them, two steroidal glycosides, 1 (mp 245-249°, [α] D-45.1°) and 2 (mp 214-218°, [α] D-26.5°, Ehrlich reaction +, a bitter principle), were characterized as 3-O-(β-D-glc·pyr-^^(1→2)β-D-glc·pyr-^^(1→4)β-D-gal·pyr)-spirostanol derivative (a mixture of tigogenin, neotigogenin, diosgenin and yamogenin) (1) and the corresponding furostanol 26-O-β-D-glc·pyranoside (2).
