β 1 ‐Solamargine and three new glycoalkaloids, robustine, N ‐hydroxyrobustine, and 25‐acetoxyrobustine, have been isolated from the roots of Solanum robustum , the structures of which have been elucidated as 3‐ O ‐{ O ‐α‐ L ‐arabinopyranosyl‐(1→3)‐ O ‐[α‐ L ‐rhamnopyranosyl‐(1→2)]‐ O ‐[α‐ L ‐rhamnopyranosyl‐(1→4)]‐(β‐ D ‐glucopyranosyl}solasodine ( 3 )), its N ‐hydroxy, and its 25‐acetoxy derivative. These compounds have characteristic structures in comparison with the hitherto known Solanum glycoalkaloids.
