Abstract
A steroidal saponin, named tuberoside, together with seven known compounds, were isolated from the seeds of Allium tuberosum Rottl. ex Spreng. Its str ucture was established by spectroscopic data, hydrolysis, and comparison wi th spectral data of known compounds to be (2 alpha, 3 beta, 5 alpha, 25S)-2 ,3,27-trihydroxyspirostane 3-O-alpha -L-rhamnopyranoyl-(1-->2)-O-[alpha -L- rhamnopyranoyl-(1-->4)](beta -D-glucopyranoside.
