Two New Steroidal Glycosides from Solanum surattense

Two new steroidal alkaloid glycosides, solanoside A (1) and solanoside B (2), were isolated from the whole plant of Solanum surattense. Their structures were elucidated on the basis of spectroscopic techniques (1D and 2D NMR, HR-EI-MS, HR-FAB-MS, IR), physical data, and chemical analysis.
