Five new steroidal alkaloid glycosides, 1 – 5 , along with the known analog 6 , have been isolated from the aerial parts of Solanum tuberosum. The structures of the new compounds were elucidated by spectroscopic methods, including 1D‐ and 2D‐NMR and HR‐ESI‐MS techniques, as well as by comparison of the spectral data with those of related compounds. Only compound 6 showed significant cytotoxicity.
