Bufadienolides from Drimia robusta and Urginea altissima (Hyacinthaceae).
The bufadienolides, 6beta-acetoxy-3beta,8beta,12beta,14beta-tetrahydroxybufa-4,20,22-trienolide (12beta-hydroxyscillirosidin) (1) and 14beta-hydroxybufa-4,20,22-trienolide 3beta-O-[alpha-L-rhamnopyranosyl-[(1-->4)-beta-D-glucopyranosyl]-(1-->3)-alpha-L-rhamnopyranoside] (urginin) (2) were isolated from Drimia robusta and Urginea altissima, respectively.
