摘要：

The structures of three new steroidal alkaloid glycosides named solaverines I, II and III were isolated from the aerial parts of Solanum toxicarium and S. verbascifolium and their structures, including the new sapogenols solaverols A and B, were elucidated as (22R, 25R)-3β, 23α-dihydroxyspirosol-5-ene 3-O-α-L-rhamnopyranosyl-(1→2)-[α-L-rhamnopyranosyl-(1→4)]-β-D-glucopyranoside, (22R, 25R)-3β, 23α-dihydroxyspirosol-5-ene 3-O-α-L-rhamnopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→3)]-β-D-galactopyranoside and (22R, 25R)-3β, 23α, 27-trihydroxyspirosol-5-ene 3-O-α-L-rhamnopyranosyl-(1→2)-[α-L-rhamnopyranosyl-(1→4)]-β-D-glucopyranoside, respectively. © 1990, The Pharmaceutical Society of Japan.
