Bufadienolides from Drimia robusta and Urginea epigea (Hyacinthaceae).
Two bufadienolides, 6beta-acetoxy-3beta,8beta,14beta-trihydroxy-12-oxobufa-4,20,22-trienolide and 14beta-hydroxybufa-3,5,20,22-tetraenolide were isolated from the dichloromethane extract of the bulbs of Drimia robusta and the methanol extract of the bulbs of Urginea epigea, respectively. The bulbs of Drimia robusta also yielded several known compounds, 6beta-acetoxy-3beta,8beta,12beta,14beta-tetrahydroxybufa-4,20,22-trienolide (12beta-hydroxyscillirosidin) from the dichloromethane extract and three common aromatic acids, 4-hydroxy-3-methoxybenzoic acid, 3,4-dihydroxybenzoic acid, and trans-3-(4'-hydroxyphenyl)-2-propenoic acid from the ethyl acetate extract.
